Preparation 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 کاملsynthesis of poly(para-phenylene terephthalamide) and preparation of short fibers: effect of sodium sulphate on the fibers
kevlar is one of the fbers which is used in heavy industrial productions such as, shipping, military and weaving for reinforcement of composites. initial polymer of kevlar or poly(para-phenylene terephthalamide) is an oriented liquid crystal polymer. existence of aromatic group in the main chain leads to formation of rigid-rod molecules in the polymer, high strength and high modulus in it is fb...
متن کاملRetention 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 کاملon translation of phatic communion and socio-cultural relationships between the characters of the novels
phatic communion is a cultural concept which differs across cultures. according to hofstede (2001), the u.s. tends to have individualistic culture; however, asian countries tend to have collectivistic cultures. these cultures view phatic communion differently. in individualistic cultures like u.s., phatic communion reflects speakers’ socio-cultural relationships in conversations. to see whether...
15 صفحه اولA 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.
