A cation-conducting polymer has two or more repeating units of the following formula Owing to the cation-conducting polymer has good physicochemical properties, hydrolytic stability and conductivity, a film formed by coating the liquid cation-conducting polymer can be used as proton exchange membrane to apply in fuel cell system.

Cation-conducting polymer

A polymer of fluorine-containing sulfonated poly(arylene ether)s and a manufacturing method thereof are provided. The polymer is formed by processing a nucleophilic polycondensation between a fluorine-containing monomer having an electron-withdrawing group and a multi-phenyl monomer. A main structure of the polymer of fluorine-containing sulfonated poly(arylene ether)s has a first portion with fluoro or trifluoromethyl substituted phenyl groups, and a second portion with sulfonated phenyl groups.

Polymer of fluorine-containing sulfonated poly(arylene ether)s and method of manufacturing the same

A polymer of poly(arylene ether)s, a manufacturing method thereof, and a polymer light emitting diode with an organic light emitting layer made from the polymer are provided. The polymer is formed by processing a nucleophilic polycondensation between a fluoro-containing monomer having an electron-withdrawing group and a multi-phenyl monomer. The polymer has a host portion with fluoro- or trifluoromethyl substituents, and a customer portion with multi-phenyl groups.

Polymer of poly(arylene ether)s, manufacturing method thereof and polymer light emitting diode with organic light emitting layer made from the same

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.

Polymer of sulfonated poly(arlene ether)s and manufacturing method thereof

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.
