Abstract

Nanophase-separated poly(2-hydroxyethyl methacrylate)-l-polyisobutylene (PHEMA-l-PIB) amphiphilic conetworks were obtained by crosslinking α,ω-bismethacrylate-terminated polyisobutylene (PIB) via copolymerization with silylated 2-hydroxyethyl methacylate, followed by the hydrolysis of the silyether groups. Morphology development of a sample containing 64% PIB was monitored by means of transmission electron microscopy (TEM), atomic force microscopy (AFM), and small-angle X-ray scattering. For comparison, the morphology of a sample containing 53% PIB was investigated by AFM. The dry conetworks exhibited hydrophilic and hydrophobic phases with average 8-10-nm domain sizes and were swellable in water as well as in heptane. Swelling amphiphilic conetworks with aqueous cadmium-chloride solution followed by exposure to H2S resulted in nanosized CdS clusters located in the amphiphilic conetworks, that is, for the first time, new inorganic-organic hybrid materials composed of CdS semiconducting nanocrystals and PHEMA-l-PIB amphiphilic conetworks were prepared.
