抄録

Surface free energy of a nanofiller is an important factor to control the property of polymer nanohybrid materials. In this study, cyclopentyl substituted polyhedral oligomeric silsesquioxane (CpPOSS) was used as a nanofiller. CpPOSS model surface was prepared on a silicon substrate by immobilization of cyclopentyltrimethoxysilane on a silicon substrate, and the surface free energies of the POSS model surfaces were evaluated from static contact angle measurements. In addition, the dispersion structure of CpPOSS in polystyrene (PS) thin films is discussed. Neutron reflectivity measurement revealed that CpPOSS segregated to the film surface because CpPOSS has lower surface energy than PS. CpPOSS also segregated to the film-substrate interface. The dispersion state of CpPOSS in the films, which can change the morphology and enrgetics of the films, seems to contribute to the thermal stability of the films.
