聚硅氧烷/钛溶胶光催化复合膜的光催化降解作用
DOI: 10.11777/j.issn1000-3304.2015.14148, PP. 1-7

Abstract:
以锐钛型的钛溶胶和粉体TiO2为光催化材料,以聚硅氧烷(PDMS)和聚丙烯酸酯(PA)为黏合剂,制得相应的光催化复合膜.通过X-射线衍射分析、粒度分析、电镜观察等手段比较2种TiO2颗粒的晶型及其在有机介质和复合膜中的分散状态,通过光学显微观察、载体降解失重评估、染液吸光度测定等方式考察TiO2对两类黏合剂和酸性品红6B染料分子的光催化降解作用.发现溶胶-凝胶法可制得结晶程度较高的锐钛型钛溶胶,且所制颗粒晶粒更小、与有机介质和黏合剂的相容性更好,在复合膜中分散更均匀,因而更易光催化降解接近复合膜的染料分子,但同时也更易老化降解以低键能C—C键为主链的常规碳链黏合剂.而聚硅氧烷以高键能的Si—O键为主链,其抵御光催化所产高能自由基的氧化-还原作用的能力更强,是一种理想的光催化有机载体.通过聚硅氧烷与钛溶胶的有效复合,可在保证复合膜稳定性的同时赋予其更强的光催化降解作用.
