Linear poly(p-phenylene)s are modestly active UV photocatalysts for hydrogen production in the presence of a sacrificial electron donor. Introduction of planarized fluorene, carbazole, dibenzo[b,d]thiophene or dibenzo[b,d]thiophene sulfone units greatly enhances the H2 evolution rate. The most active dibenzo[b,d]thiophene sulfone co-polymer has a UV photocatalytic activity that rivals TiO2, but...
This paper presents a hierarchically designed polymer nanocomposite approach in which nanofillers at ultralow volume loading generate large dielectric enhancement blends of high temperature polymers with tailored nanostructures. We blend poly(1,4-phenylenen ether sulfone) (PES) polymers, such as polyetherimide (PEI), that possess more coiled chain conformations to tailor nano-morphologies. Maki...
