ABSTRACT
New
ultrafiltration
membranes
are
created
by
self-assembly of
block polymers
and
non-solvent
induced
phase
separation
techniques
(SNIPS).
Providing a
platform with
a hierarchical
and
well-
defined
porous
network, these
membranes
offer
high
selectivity and
permeability,
along with
good
mechanical
responses.
It has
been
proven
that SNIPS
membranes
could exhibit
superior
performance
than the
state-of-the-art
commercial
membranes.
However, a
major challenge
towards
the creation
of a
commercial
product is to
manufacture
SNIPS membranes
by
continuous
casting
techniques. Hence,
it is
necessary to
elucidate the
fundamental
physical
principles
of SNIPS
casting solutions to
start building a
mass production casting
process.
It is believed that the
SNIPS
solutions’ flow behavior
has a strong
correlation with
the final morphology
of membranes
fabricated
via roll-to-roll
casting
techniques. In
this proposal,
rheometry
is introduced
as a
powerful
tool to
characterize
the SNIPS
solutions’
flow behavior
and
to elucidate
the structure-
properties-performance interrelationships of SNIPS
solutions.
