摘　　要：采用自由基聚合法合成丙烯酸树脂,之后与改性二氧化硅纳米粒子复合,制备出了新型超疏水材料,并获得了最佳涂层工艺条件。利用扫描电子显微镜(SEM)、傅里叶变换红外光谱仪、静态接触角测定仪对材料结构和性能进行了表征。结果表明,纳米二氧化硅的加入,能够极大地增加涂层表面的粗糙度,从而使材料的比表面积显著增加,根据Wenzel-Cassie模型原理,材料最终达到了超疏水结构。Acrylic resin was synthesised by radical polymerization, then composited with modified SiO2 nano-particles to give a new superhydrophobic material. The optimal coating conditions were also obtained. The material was characterized by scanning electron microscopy, Fourier transform infrared spectrometry and static contact angle measurement. The results show that： Compounding with nano-SiO2 increased the roughness of the surface of the coating, so that the specific surface areas was improved significantly. According to Wenzel-Cassie＇ s model, the materi- al had superhydrophobic structure.
