| 摘 要： | 利用硅烷偶联剂(KH-570)对纳米二氧化钛(TiO2)进行湿法改性处理.采用静态沉淀法、亲油化度、接触角、X射线光电子能谱( XPS)和傅立叶红外光谱(FT-IR)等手段对改性效果进行分析表征,探析湿法改性机理.研究表明KH-570以化学链形式结合于TiO2表面,改性后TiO2的表面性质由亲水变为亲油.

| Abstract: | The titanium dioxide(TiO) nano particles were wet modified with silane coupling agent KH-570.The TiO samples 2 2 before and after modification were analyzed and characterized by static precipitation,degree of oil-affinity,contact angle,X-ray photoelectron spectroscopy(XPS) and Fourier transformed infrared spectroscopy(FT-IR).Results showed that KH-570 was bonded on the surface of TiO,a firm chemical bonding of KH-570 to TiO film and an organic layer were formed.The modified TiO surface was 2 2 2 changed from hydrophilic to hydrophobic. |
