中文摘要：

将不同组成的氟硅与甲基丙烯酸甲酯两嵌段共聚物配制成溶液，经旋涂、退火处理后得到不同厚度的聚合物涂层。采用视频接触角张力仪（CAM）、原子力显微镜（AF、M）和X射线光电子能谱仪（XPS）研究嵌段共聚物涂层的疏水性能、表面形貌以及化学组成随涂层厚度的变化情况。结果表明：随着涂层厚度的增加，涂层表面对水、甲酰胺、二碘甲烷的接触角逐渐增大，并且聚合物涂层表面氟元素含量逐渐上升。

英文摘要：

The polymer coating with different thickness was obtained after spinning coating and annealing treatment of block copolymers of fluorosilicone and methyl methacrylate. The changes in hydrophobic properties, surface morphology and chemical composition of block copolymers with coating thickness were investigated by contact angle measurement instrument （CAM）, atomic force microscope （AFM） and X-ray photoelectron spectroscopy （XPS）. The results show that the contact angle of water, formamide and diiodomethane on the coating surface gradually increased with the increase of the coating thickness, and the fluorine content on surface also gradually increased with the increase ot7 the film thickness.
