Surface derivatization of Kevlar, poly(p-phenylene terephthalamide), fiber has been studied along with the evaluation of the surface characteristics of the chemically-modified fiber as the stationary phase in packed-capillary gas chromatography (GC). Several experimental parameters in the derivatization reaction have been optimized, and the retention behavior of the surface-derivatized fibrous ...
There have been numerous studies on ion-track membranes of poly(ethylene terephthalate) (PET) and polycarbonate (PC), which are easily prepared by ion beam irradiation and subsequent alkaline etching. More importantly, the ion-track membranes of chemically and thermally stable polyimide (PI) and polyamide (PA), with controlled pore shape and size, may be required for the design of materials tha...
