METHOD OF PRODUCING CARBON MOLECULAR SIEVE MEMBRANES

A method of forming a carbon molecular sieve membrane includes dissolving a halogenated precursor polymer in a solvent, thereby forming a dissolved halogenated precursor polymer. Homogeneously dehydrohalogenating the dissolved halogenated precursor polymer with an organic amine base to form a partia...

Zusammenfassung:A method of forming a carbon molecular sieve membrane includes dissolving a halogenated precursor polymer in a solvent, thereby forming a dissolved halogenated precursor polymer. Homogeneously dehydrohalogenating the dissolved halogenated precursor polymer with an organic amine base to form a partially dehydrohalogenated polymer. Forming a thin film from the partially dehydrohalogenated polymer. Pyrolyzing the thin film to form the carbon molecular sieve membrane.
