Abstract: A polymer of sulfonated poly(arylene ether)s (PAEs) and a manufacturing method thereof are provided. A main structure of the PAEs has a first side formed by multi-phenyl glycol monomer and a second side formed by multi-phenyl dihalo monomer with an electron-withdrawing group. The glycol monomer and the dihalo monomer are reacted with each other by a nucleophilic displacement reaction, so as to form the main structure of the PAEs. A film made of the PAEs has a better size stability under a high water uptake.

Abstract: A fuel cell catalyst layer having sulfonated poly(arylene ether)s and a manufacturing method therefor are provided. The manufacturing method includes steps of: providing at least one type of sulfonated poly(arylene ether)s; mixing the sulfonated poly(arylene ether)s with a catalyst composition to prepare a catalyst slurry; and coating the catalyst slurry to form a film which is dried to be an electrode catalyst layer, in which the weight ratio of the sulfonated poly(arylene ether)s is 5-50 wt %. The sulfonated poly(arylene ether)s in the electrode catalyst layer can provide good thermal stability, glass transition temperature, chemical resistance, mechanical properties, water impermeability, low proton transmission loss, and a relatively simple process to shorten the manufacturing time and lower the cost thereof.

Abstract: Thin films of substantially pure soluble polythiophenes and oligothiophenes undergo cross-linking and insolubilization upon irradiation with UV/visible light, without additives. Irradiation of thin polymer films through a photomask and subsequent development with solvent leaves a polymeric image of the mask. The resulting .pi.-conjugated polymeric pattern can be rendered electronically conducting by oxidation. The electronic conductivity of these films is high and is similar to that found for oxidized, non-irradiated films. Furthermore, the conductivity can be regulated over eight orders of magnitude by controlled oxidation. Thus, the fabrication of electronically conducting, organic "wires" or "channels" using conventional semiconductor photolithographic techniques can be achieved.
