氮钒共掺杂纳米tio2的表面改性及其对涂料中甲醛的降解
Keywords: 氮钒共掺杂纳米tio2,kh570,表面改性,甲醛,亲油化度
Abstract:
？利用硅烷偶联剂（kh570）对氮钒共掺杂纳米tio2进行表面改性，考察了偶联剂用量、反应时间、反应温度及ph等改性条件的影响，从而确定最佳用量和最佳反应条件。利用元素分析、红外光谱、透射电子显微镜和热质等表征手段及亲油化度的测定，研究了表面改性的效果及分散状况。红外光谱表明，kh570以化学键合的方式结合在纳米tio2的表面，并形成了有机包覆层，经测量，氮钒共掺杂纳米tio2表面包覆的kh570的质量分数约为13.36%～14.99%。将改性后的氮钒共掺杂纳米tio2以一定的比例加入到成膜物质中制成一系列的涂料样品，然后测定其甲醛含量。结果表明，甲醛的降解率可达到82.2%。与普通涂料相比，加入改性后的氮钒共掺杂的纳米tio2的涂料具有优异的物理性能。
