| 摘 要： | 基于溶胶凝胶(sol-gel)工艺,采用两步法,以正硅酸乙酯(TEOS)、甲基三乙氧基硅烷(MTES)、己二酸、聚乙二醇400(PEG 400)为原料,制备了疏水型醇酸树脂/SiO2有机无机杂化材料。MTES的Si-CH3基团赋予材料的疏水性能,随着MTES含量的提高,接触角θ增大,当MTES(质量分数,下同)超过15%时,接触角θ增大不明显,并最终稳定在126°左右。红外图谱(FT-IR)和X射线光电子能谱(XPS)分析结果显示,硅溶胶与醇酸树脂间发生了的杂化反应,形成了Si-O-C键。DSC分析结果显示,随SiO2%的提高,杂化材料的耐热性能提高。

| Abstract: | Base on sol-gel method,tetraethoxysilane(TEOS),methylethoxysilane(MTES),adipic acid and polyethylene glycol 400(PEG400) were used to synthesize hydrophobic alkyd resin/SiO2 organic-inorganic hybrid material by two-step method.The Si-methyl groups of MTES contribute to hydrophobicity of the hybrid material.The contact angle θ on the surface of hybrid material is increased with the increase of the MTES mass fraction and keeps stable at about 126° for w(MTES)>15%.The transform infrared spectroscopy(FT-IR) and X-ray photoelectron spectroscopy(XPS) spectra show that alkyd resin can hybridize with silica sol and form Si-O-C bonds.Moreover,the differential scanning calorimetry(DSC) results show that the heat resistant property of the hydrophobic alkyd resin/SiO2 organic-inorganic hybrid material has being improved with the increase of the SiO2 mass fraction. |
