Abstract

In this study, a novel composite for a soft-tissue-compatible material was developed. A surface of poly(ethylene terephthalate) (PET) fabric was modified with nano-sized hydroxyapatite (HAp) crystals through covalent bonding. In order to make covalent bonding between the HAp crystal and the PET surface, poly(γ-methacryloxypropyl triethoxysilane) poly(MPTS) was grafted on the PET surface treated by H2O2. The surface modification of PET with poly(MPTS) was confirmed by the weight gaining and X-ray photoelectron spectroscopy. The chemical reaction between OH groups on the HAp crystals and ethoxysilyl groups on the PET was conducted at 80°C for 2h in reduced pressure. It was confirmed that HAp/PET composite was not toxic by microscopic observation. The cell adhesion test of HAp/PET composite will be reported on the presentation.
