摘要：

An anionic surfactant comprising a hydrophilic poly(ethylene glycol) (PEG) chain, hydrophobic alkyl chain, and polymerizable vinyl group was synthesized as a capping agent of nanoparticles. TiO(2) nanoparticles modified by this surfactant were completely dispersible in various organic solvents with a wide range of polarities, such as nitrites, alcohols, ketones, and acetates. Furthermore, these particles were found to be dispersible in various polymers with different properties, such as thermosetting epoxy resins and radical polymerized poly (methylmethacrylate) (PMMA). A polymer composite of surface-modified TiO(2) nanopartictes in epoxy resins prepared by using the developed surfactant also possessed temperature-induced shape memory properties.
