采用模板自组装技术以氧化亚铜为模板制备了聚苯胺/二氧化钛(PANI/TiO2)复合材料,通过傅里叶红外光谱仪、激光粒度分析仪、紫外可见分光光度计和热分析仪对不同比例复合的聚苯胺/二氧化钛材料进行了表征。研究结果表明:在反应时间、反应温度和催化剂用量等条件保持不变的情况下,苯胺(ANI)用量对复合材料的形貌和性能有着重要的影响。聚苯胺的复合使得聚苯胺/二氧化钛的粒径均比纯二氧化钛的有所增大,但随着苯胺用量的增大,粒径呈减小的趋势。可见光催化复合材料降解苯酚的研究表明,聚苯胺复合有利于光催化效率的提高;复合材料的光催化性能随着苯胺含量的增加呈现先升高后降低的趋势。
Polyaniline / titania (PANI / TiO2) composites were prepared by template self-assembly technique using cuprous oxide as a template. The PANI / TiO2 composites were characterized by Fourier transform infrared spectroscopy, laser particle size analyzer, UV-visible spectrophotometer and thermal analyzer Polyaniline / titania materials were characterized. The results show that the amount of aniline (ANI) has an important influence on the morphology and properties of the composites under the conditions of reaction time, reaction temperature and catalyst dosage. Polyaniline composite makes polyaniline / titanium dioxide particle size than pure titanium dioxide has increased, but with aniline dosage increases, the particle size tends to decrease. Visible photocatalytic degradation of phenol composite materials showed that the polyaniline composite is conducive to the improvement of photocatalytic efficiency; composite photocatalytic performance with the increase of aniline content showed the first increase and then decrease.
