SYNTHESIS AND CHARACTERIZATION OF HIERARCHICAL STRUCTURE IN SUPERCRITICAL CO_2-FABRICATED COMPOSITES

摘要

This paper illustrates the fabrication of two unique nanocomposite materials. These composites are synthesized via a supercritical CO_2-assisted process similar to a rim and rtm technique. The use of SC CO_2 in the fabrication of fiber-reinforced composites allows for the templated deposition of resin into the fiber's crystal structure. Utilizing SC CO_2 in the synthesis of intercalated silicate nano-composites significantly lowers viscosity and allows for synthesis of nanocomposites containing saturated levels (>40%) of organically modified layered silicates (OMLS).
