摘要：为了提高基体材料的防污能力，在基体表面制备了一种无氟超疏水复合涂层。首先，使用十六烷基三甲
氧基硅烷（HDTMS）对二氧化硅（SiO 2 ）微纳米颗粒进行疏水改性，其次，将改性后的 SiO 2 颗粒与有机硅烷
混合，利用硅烷的水解、聚合在基体材料的表面得到一层稳定的无氟超疏水复合涂层。采用 FTIR、TGA、SEM、
AFM 和接触角测量仪对涂层的化学组成、表面微观结构和疏水性能进行表征。结果表明：复合涂层表面具有微
纳米尺度的粗糙结构，并具有优异的自清洁性和耐磨损性；未磨损前接触角达 151°，磨损 100 周次后接触角进
一步提高至 161°。

Abstract: In order to improve the antifouling ability of the base material, fluorine-free superhydrophobic
composite coatings were prepared on the surface of the substrate. In this work, silica (SiO 2)
micro-nanoparticles were modified by hexadecyltrimethoxysilane (HDTMS). Subsequently, the modified
SiO 2 micro-nanoparticles were blended with organic silane. Finally, stable fluorine-free hydrophobic
composite coatings on the surface of the substrate were prepared via hydrolysis and polymerization of
organic silane on the modified SiO 2 micro-nanoparticles. The chemical compositions, morphology and
hydrophobic properties of the coatings were characterized by FTIR,TGA,SEM,AFM, and water contact
angle measurements. The results showed that the surface of the composite coating had a rough micro-nano
scale structure, with excellent self-cleaning properties and wear resistance. The contact angle of the coating
reached up to 161° after an abrasion treatment of 100 cycles, which was higher than that of the coating
without the abrasion treatment (151°).
