摘　　要：利用十八烷基三甲氧基硅烷(ODTMS)对二氧化钛(TiO_(2))晶须进行改性,并通过溶液共混法将其添加到涂层溶液中,制备了硅烷改性TiO_(2)/PVDF超疏水涂层,通过扫描电子显微镜(SEM)和红外光谱(FTIR)对涂层进行形貌和结构分析。结果表明,经过360 h的阻垢实验,硅烷改性TiO_(2)/PVDF超疏水涂层表面的CaCO_(3)结垢量仅为1.90 mg/cm^(2),相较于PVDF涂层和TiO_(2)/PVDF涂层分别减少了37.1%和16.7%。硅烷改性TiO_(2)晶须在涂层中的分散性优良,在涂层中形成空间限制,使得CaCO_(3)晶体的生长方向受到限制,从而抑制垢的形成。TiO_(2)Whisks were modified by octadecyl trimethoxysilane(ODTMS)and added to the coating solution by solution blending method.The silane modified TiO_(2)/PVDF/superhydrophobic coating was designed and prepared the morphology and structure of the coating were analyzed by scanning electron microscopy(SEM)and infrared spectroscopy(FTIR).The results showed that after a 360 h scaling experiment,the CaCO_(3)scaling amount on the surface of silane modified TiO_(2)/PVDF superhydrophobic coating is only 1.90 mg/cm 2,which was 37.1%and 16.7%less than PVDF coating and TiO_(2)/PVDF coating,respectively.The dispersion of silane-modified TiO_(2)whisker is excellent,and spatial limitations are formed in the coating,which limits the growth direction of CaCO_(3)crystals and inhibits the formation of scale.
