摘要:
Hybrid semiconductor materials have an inorganic semiconductor incorporated into a hole-conductive fluorene copolymer film. Nanometer-sized particles of the inorganic semiconductor may be prepared by mixing inorganic semiconductor precursors with a steric-hindering coordinating solvent and heating the mixture with microwaves to a temperature below the boiling point of the solvent.

摘要:
Ion-exchange materials comprising a polymeric backbone and a plurality of pendent styrenic or fluoridated styrenic macromonomers covalently bonded thereto, wherein the plurality of pendent styrenic or fluorinated styrenic macromonomers comprise a uniform number of styrenic or fluoridated styrenic monomer repeat units, and wherein predominantly all of the styrenic or fluoridated styrenic monomer repeat units have at least one charged group. Processes for making such material, as well as products related thereto, are also disclosed. In a representative embodiment, the ion-exchange material is utilized as a proton-exchange membrane (PEM) for use in a PEM fuel cell.
