Tunable composite membranes for gas separations. Quarterly report, July - September 1996
During this past quarter of project DE-FG22-94PC94222, continued significant progress was made in the synthesis and characterization of conducting polymer composite membranes for gas separations. Highlights from this funding period include: fabrication of poly(dodecylthiophene), PDDT (M{sub w}=250K), membranes and characterization by light microscopy (LM), scanning electron microscopy (SEM) and atomic force microscopy (AFM); permeability measurements for neutral and chemically oxidized PDDT membranes; extension of previous work on poly(octylthiophene)-zeolite (POT- NaY)composite membranes of different compositions; preparation of tin(IV) sulfides to be incorporated as microporous, {ital electrically conducting}, additives in the composite membranes; synthesis of poly(trioxynonylthiophene) and membrane fabrication and characterization; talks published in the Proceedings of Microscopy and Microanalysis, 1996, Minneapolis, MN, August 11-15, 1996, and presented at the 212th American Chemical Society National Meeting, Orlando, FL, Aug. 25-29, 1996 and at the 52nd American Chemical Society Southwest Regional Meeting, Houston, TX, October 17-19, 1996. 2 figs., 2 tabs.
