Abstract Details

2018, Master of Science, University of Akron, Polymer Engineering.
Aerogel is a synthetic nanoporous functional material with abundant unique properties, such as ultralow thermal conductivity and ultralow modulus. Many achievements were reported about silica aerogel, however, related researches on polymer aerogel are not deep enough, especially for d form syndiotactic polystyrene (sPS) aerogels. This research investigated at the modification of sulfonated syndiotactic polystyrene aerogels, through an ion-exchange reaction with semi-telechelic, quaternary phosphonium functionalized poly (tert-butyl styrene) (PtBS) synthesized by reversible addition fragmentation chain transfer (RAFT) agent. Synthesis and purification of ionic PtBS were key factors in this research, which also involves the synthesis of ion-containing RAFT agent. The end group functionality of PtBS was examined by thin layer chromatography (TLC) and purification was achieved by column chromatography. Syndiotactic polystyrene (sPS) was sulfonated with acetyl sulfate reagent and neutralized with methanolic sodium hydroxide. The H1 NMR and FT-IR were used for characterization, which verified the chemical structure of RAFT agent, PtBS, sulfonated syndiotactic styrene and SsPS-PtBS aerogels.
