The Use of Functionalized Polybenzoxazoles and Polybenzobisthiazoles in Polymer-Silica Hybrid Materials
Published online by Cambridge University Press: 10 February 2011
Abstract
Hybrid organic-inorganic composites were prepared by precipitating silica into hydroxypolybenzoxazole (HPBO) and sulfopolybenzobisthiazole (SPBT) polymers, with interfacial bonding between the phases improved by use of isocyanatopropyltriethoxy silane and N,N-diethylaminopropyltrimethoxy silane, respectively. The resulting materials were characterized with regard to their transparency, silica particle distribution, tensile modulus and tensile strength, thermal stability, and tendency to absorb water.
