Vapor Grown Carbon Fiber/Hybrid Organic-Inorganic Matrix Composites. Nanometer-sized Silsesquiozane Phase Chemically Bound in a Matrix.

摘要

The goals of our research under AFOSR Grant number F49620-99-0191 (continued under F49620-02-0260) were to explore the preparation, properties and applications of organic matrix resin nanocomposites. The dispersed nanophases selected for this work included: (1) Polyhedral oligomeric silsesquioxane chemicals (POSS macromers) of three types: those with no polymerizable group, those with one reactive function and those with eight reactive functions. At first this included only the T8-POSS family (R8Si8O12), but later we expanded the work to the T10-POSS (R10Si10O15) and T12-POSS (R12Si12O18) families. (2) Vapor grown carbon nanofibers produced by ASI Cederville, OH (60-250 nm diameters). (3) Nanodispersed montmiorillonite clays.
