Please consider attending the following: MATERIALS ENGINEERING SEMINAR "Orientation of Polymer Films for Improvement of Dielectric Properties in High-Energy Density Capacitor Applications" By Megan Forshey Purdue MSE Ph.D. Final Exam Advisor: Professor Mukerrem Cakmak ABSTRACT For over 20 years, biaxially oriented polypropylene (BOPP) has been used in capacitors as the dielectric material. BOPP has very high breakdown strength, low electric loss, and is relatively inexpensive however, it suffers from low dielectric constant and low usage temperature. The ever growing technology market requires more robust capacitors which can be used in high temperature and pulsed power applications, and the aim of this research is to meet or exceed dielectric properties of BOPP by combining specific polymer materials in layered structures, biaxially orienting the films, and heat setting the films to further improve thermal stability. Post-processing is done on custom built machines which track real-time true stress, true strain and birefringence values, allowing for a more complete picture of mechano-optical properties generated during the stretching process. This data, along with offline characterization techniques such as X-ray scattering and DSC was coupled with dielectric property testing to help form relationships between polymer processing, morphology, and dielectric properties. A 32 Layer film consisting of 50:50 vol ratio of poly(ethylene terephthalate) (PET) and poly(vinylidene fluoride) (PVDF) was provided by PolymerPlus, Inc. Since ideal processing temperatures for PET and PVDF do not match, an initial uniaxial stretching study was conducted over a wide range of stretching temperatures to determine effect of final morphology on starting state of each polymer. For this film, we have established ideal processing temperature to be a very narrow range between 145-155o C. Uniaxial stretching at several temperatures was conducted for further morphological time slice study. Characterization confirmed PVDF crystal form transformation from α to β when films were stretched at 95o C, and presence of γ PVDF due to annealing effect when stretched at 185o C (near equilibrium melting point of PVDF). Dielectric testing experiments at room temperature show that films stretched uniaxially at 95o C have higher dielectric constant but also significantly higher dielectric loss. Films stretched at 150o C have lower dielectric constant but also much lower loss, making them a better candidate for improved dielectric film in capacitor applications. Thermal annealing is used in industry to heat set oriented polymer films for further use at high temperature, such as BOPP in capacitors. 32L PET/PVDF microlayer films were oriented and further annealed to study effect on morphology. Only uniaxial mode and very small simultaneous stretch ratios were feasible. Annealing over a range of temperatures around PVDF melting peak caused transformation of PVDF polymorphs which were studied via DSC, WAXS and FTIR. Finally, morphology was correlated with dielectric constant and loss values in both constant (room) temperature and temperature ramping experiments. For the most part, samples containing γ and/or γ'-PVDF showed improved dielectric constant but also much higher loss values in temperature ramp dielectric testing.

MSE safety training requirements
by Erk, Kendra A 06 Sep '19

06 Sep '19

View current requirements as PDF: https://engineering.purdue.edu/Intranet/Groups/Schools/MSE/Facilities/Safet… Dear MSE Students, Faculty, and Staff, Copied below are the current safety training requirements for individuals affiliated with MSE. For students and technical personnel, the training modules and documentation records are now maintained through the MSE Lab Safety Blackboard course. Many of you have already been enrolled in this course (it should be listed on your Blackboard Dashboard). For those that have not, click here<https://mycourses.purdue.edu/webapps/blackboard/execute/viewCatalog?id=&typ…> to self-enroll or contact Jenni Fifer. Annual Requirements for Administrative Staff Each calendar year, administrative staff are required to complete the "awareness" HazCom training, which consists of an online, 15-minute module. Link to training<https://www.purdue.edu/ehps/rem/training/training.html#H> . To document your training in the MSE records, forward your completion confirmation email to mse-safety(a)purdue.edu<mailto:mse-safety@purdue.edu> . On-Boarding Requirements for Students and Technical Personnel Within 1 month of their appointment, all NEW faculty, technical staff, undergraduate students, graduate students, postdoctoral researchers, and other research-active personnel (including long-term visitors, summer REUs, lab course teaching assistants), are required to complete the following three training modules: 1. "Comprehensive" HazCom training 2. Chemical Hygiene Plan (CHP) training on "Lab Safety Fundamentals" 3. MSE-specific safety training (slides & quiz) Visit the MSE Lab Safety Blackboard Course<https://mycourses.purdue.edu/webapps/blackboard/execute/viewCatalog?id=&typ…> to complete these trainings. These training modules must be completed before requesting lab access and before working independently within an MSE-managed research or teaching lab space, including spaces in ARMS and MSEE as well as select labs in FLEX and Kepner. Annual Requirements for Students and Technical Personnel Each calendar year, all faculty, technical staff, undergraduate students, graduate students, postdoctoral researchers, and other research-active personnel are required to attend ONE in-person safety "refresher" training. Options for this refresher training include the following: * MSE 690 or MSE 390 safety seminar, led by MSE Safety Officer (next session is on Sept 13th, ARMS 1010 at 3:45 pm; all are welcome) * MSE 430 (Senior Design) safety seminar, led by MSE Safety Officer (typically 1 per year) * Research-specific safety meeting**, led by an MSE faculty member (recurring) Additionally, each calendar year, all undergraduate students, graduate students, and postdoctoral researchers are required to complete the MSE-specific safety training (slides & quiz) administered through the MSE Lab Safety Blackboard course. **Note that the research-specific safety meetings are required to address eight ppt slides provided by the MSE Safety Officer, which include guidance on how to document the training within MSE records. The meeting can then discuss policies and issues of relevance to the specific group of people. Interested faculty members should contact Prof. Erk for more details.

West Coast Swing Dance Callout - Tomorrow
by Jessica L Sargent 05 Sep '19

05 Sep '19

Hi guys! This is not particularly a GSA thing, but I wanted to see if anyone would be interested in getting an MSE group together for this. I'm really interested in attending the West Coast Swing Dance (Purdue Westies) club's callout tomorrow at 6 pm. West Coast swing is essentially a smoother variation on the traditional Lindy Hop style swing dancing you see in movies, etc. Swing dancing is primarily a partnered dance, but it's very social and typically encourages dancing with everyone in the room rather than sticking to a "date" or partner you come with, so it's a great chance to meet people. The callout is in Stewart Center, so I thought maybe we could get a group together to grab a bite to eat between seminar and the callout. If anyone is interested in joining, let me know! Jess Jessica Sargent Ph.D. Candidate, Materials Engineering Graduate Professional, Women in Engineering Program Purdue University

ARMS Office space
by Son, Rosemary E 03 Sep '19

03 Sep '19

Dear Students and Post Docs, I am going to take inventory of the office space in ARMS. If your office is not in ARMS, please do not respond. For those who are, including Post Docs, please put a sticky note on the space you are using in the office. If your name is not on the door, for graduate students, do not mark a space. If you do not put a sticky note to indicate your space, I will assume that you are not using the space and assign it to someone else. If you are out of town, please let me know. I will be checking offices on Friday, Sept. 6. For all incoming graduate students, if your advisor and lab is located outside ARMS, your office will be at that location. Your advisor will help you get to the right person to assign space and key or location and key fob. Please let me know. For those of you who are not in ARMS, but need to use a space in ARMS, please use the computer lab ARMS 2114 as hot desk space. School of Materials Engineering Purdue University Neil Armstrong Hall of Engineering 701 West Stadium Ave. Room 2200 West Lafayette, IN 47907 765-494-4105 [PU150]
