UV-curable Organic-inorganic Hybrid Films Based on Acrylated Polyester

摘要

An UV-curable organic/inorganic hybrid films based on Acrylated polyester (AP) was prepared using the in-si-tu method of tetraethylorthosiline (TEOS) oligomers. The TEOS oligomers were prepared in presence of water and etha-nol using hydrochloric acid as a catalyst. The TEOS oligomers were characterized using ~(29)Si NMR and the acrylated polyester (AP) were characterized by MALDI-TOF mass spectra. A radical photoinitiator was added to the TEOS/AP formulation and the films were crosslinked via UV-radiation. The effects of TEOS oligomers on hybrid film properties such as tensile strength and elongation and thermal stability were investigated.
