Retention behavior on aminoethyl-modified poly(p-phenylene terephthalamide) fiber stationary phases in gas chromatography.
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 ...
متن کاملPreparation of ion-track membranes of poly(p-phenylene terephthalamide)
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...
متن کاملA facile synthetic route to poly(p-phenylene terephthalamide) with dual functional groups.
Claisen rearrangement reaction was employed for the first time to obtain a novel PPTA bearing reactive allyl and hydroxyl groups which may act as a sizing agent of Kevlar fibers to improve the interface structure and interfacial adhesion of rubber or epoxy based composites.
متن کاملRetention Behavior of Fluorobenzenes on Fluoro-Derivatized Poly(p-phenylene terephthalamide) Fibrous Stationary Phases in Microcolumn Liquid Chromatography
High performance liquid chromatography (HPLC) is one of the most important technologies in separation science in fields including agricultural, pharmaceutical, and medical science [1]. In particular, a significant degree of the performance of LC systems is due to columns which can separate complex mixtures, and columns are constantly being improved to obtain optimal separations of an enormous v...
متن کاملPhotophysics of Poly(p-Phenylene Vinylene) Films
We report on time resolved photoluminescence (PLRT) measurements in poly(p-phenylene vinylene) (PPV) films irradiated by laser in the presence of air. We observe a PL intensity enhancement and a biexponential decay dynamics of PL signal for all irradiated films. These results can be understood in terms of a chain shortening process due to carbonyl incorporation and formation of an energy profil...
