Nanocomposite Gas Separation Membrane Materials, Prof. Benny D. Freeman




Dinner Lecture

"Nanocomposite Gas Separation Membrane Materials"

Prof. Benny D. Freeman
Matthew van Winkle Professor of Chemical Engineering
University of Texas at Austin

The utility of mixing fine (~ 1 micron), porous inorganic particles, such as highly
selective zeolites, with polymeric matrices to improve gas separation properties
has been widely explored. In contrast, incorporating nanoscale (~10-50 nm),
nonporous fumed silica particles in poly(4-methyl-2-pentyne) [PMP] and other
high free volume glassy polymers increases both gas permeability and organic
vapor/permanent gas selectivity. For example, addition of 30 wt% fumed silica
to PMP simultaneously doubles mixed-gas n-butane/methane selectivity and
increases n-butane permeability 3 times relative to that of pure PMP. This
surprising discovery is contrary to previous studies of filled polymer systems
where the presence of inert filler particles serves as an obstruction to gas transport
and decreases permeability. This presentation discusses the effect of filler loading
and filler size on gas solubility, diffusivity and permeability in PMP/nanoparticle
composites and other related systems.

Upcoming GGPF meetings:

March 16, 2004
GGPF Spring Symposium (all-day event)
"Polymers in Medicine" Symposium
Michael's at Shoreline Park, Mountain View
Our 2004 Spring Symposium features 8 outstanding speakers,
including three from academia and four from industry. A diverse
range of topics will be covered, from nanoscale work on the cell/
polymer interface and vesicle stabilization, to polymer membranes
and medical device technology, to novel custom medical polymers.
Talks tend to be technology and research oriented, and interactive
audience participation is encouraged. Each talk will allow for a
substantial question and answer period, and attendees will also
have the opportunity to meet with the speakers during four schedule
Speakers / general topic:
Prof. James Anderson, Case Western / Device Cell Adhesion
Prof. Marjorie Longo, UC Davis / Vesicles - Drug Delivery
