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.

Our anniversary theme is "Giant Leaps," recalling Purdue alumnus Neil Armstrong's historic statement on the moon. The centerpiece of the Giant Leaps celebration is a yearlong Ideas Festival, already underway, focused on the most critical challenges and opportunities facing our world now and in the future. This is an 'uncommon conference' where participants will have an immersive experience in futuristic technology that should appear in 2030 to 2050. The primary objective is to organize a conference, as it would happen in the future. The conference will include a series of sessions designed to explore emerging technologies through the lens of critical issues such as privacy and community development. Other sessions include future of healthcare, factories, and art and theatre. A leading expert will introduce quantum technologies to general public as taught in 2050. We will also have a series of student competitions. In the conference room of the future at Honors Hall, designed in collaboration with Purdue's Department of Art and Design, facial expressions of participants will be analyzed. This will provide real-time feedback to the speakers and audience, helping evaluate how new ideas are received. Exhibitions include nanophotonics/laser art, semi-transparent flexible loudspeaker, artificial intelligence generated art, an interactive model to experience a fall and your heartbeat. Each participant will be given a wearable device (e.g. for monitoring sweat). The event will bring together preeminent thought leaders, practitioners, and stakeholders from across government, industry, and academia to address key questions and help us better understand and plan for the impacts of these new technologies.

Please consider attending the following: Please note the change of room EE 224 MATERIALS ENGINEERING SEMINAR "Application of Surface Severe Plastic Deformation to α+β and β Titanium Alloys for Microstructure Modification" By David A. Brice Purdue MSE Ph.D. Final Exam Advisor: Professor David F. Bahr ABSTRACT Gain refinement of metallic materials has become a popular topic for investigation because decreasing grain size improves mechanical properties; however, the production of large pieces/parts with refined grain structures is problematic. Early attempts to produce fine grained materials relied on gas condensation or milling processes that succeeded in producing nanocrystalline materials. These processes succeeded in producing small specimens that had nanocrystalline structures but exhibited decreased ductility. The use of severe plastic deformation processes, namely ECAP, have succeeded in producing ultra-fine-grained materials; however the uniform grain sizes still decrease overall ductility of the piece produced. Recently, surface deformation processes have produced localized refinement of the surface in metallic materials and reported an increase in strength along with ductility. This study focuses on the use of shot peening (SP) as a severe plastic deformation and its application to Ti based alloys, and has varied goals. Firstly, this project has used SP as a deformation process that coupled with a posthumous heat-treatment resulted in clear and consistent grain refinement in a variety of titanium alloys. The alloys used for this investigation were selected to represent classes of titanium alloys of interest to several industries, and more importantly to contrast the capabilities of lesser known alloys Ti-64. Application of SP produced clear grain refinement of surface layers that measured several microns from the surface. Significant hardening of the surface was measured as a result of the layers produced. Other effects from the processing such as precipitation of α-Ti in β-alloys was examined and shown to be influenced by elastic residual stresses. Also, the corrosion resistance of the layers was measured through Cyclic potentiodynamic polarization under conditions that mimic biological environment. Proof of concept for self-peening is reported in this study. Self-peening is the practice of performing SP with shot media composed of the same (or similar) material as the part that is being treated. Production of shot media was successfully performed through the exploitation of titanium oxidation. Evidence is provided that clearly shows decreased surface contamination when using the Ti-based shot media to shot peen Ti alloys. Additionally the surface hardening and residual stress imparted by the different shot media, while being used with identical shot peening conditions were compared.
