P(EA-MAn-APTES)/二氧化硅有机无机杂化材料的合成和表征
Synthesis and characterization of hybrid organic-inorganic materials based on EA-Man-APTES and silica
摘要
Abstract
Poly (EA-Man-APTES)/silica hybrid materials were successfully prepared from Ethyl acrylate (EA),maleic anhydride (Man) and tetraethoxysilane (TEOS) in the presence of a coupling agent 3-aminopropyltriethoxysilane (APTES),by free-radical solution polymerization and in situ sol-gel process.The mass fraction of TEOS varied from 0 to 25%.The hybrid materials were characterized by the methods of FT-IR spectra,solvent extraction,scanning electron microscope (SEM),transmission electron microscope (TEM),differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA) measuring apparatus to get their structures,gel contents,morphologies,particle sizes and thermal performances.The results show that the covalent bonds are between organic and inorganic phases,gel contents in the hybrid materials are much higher,the SiO2 phase is well dispersed in the polymer matrix,silicon dioxide exist at nanoscale in the composites and have excellent thermal stability.关键词
