| 摘 要： | 提高耐磨性能是推动仿生超疏水表面走向实际应用的关键挑战之一。设计了二氧化铈微米粒子增强PMMA/PVDF超疏水复合涂层配方,获得了水珠接触角达152°、水珠滚动角为5°的超疏水复合涂层。该涂层经过落砂磨损试验后接触角下降为103°、滚动角增大为20°。采用碳纤维颗粒对CeO2/PMMA/PVDF超疏水复合涂层进行增强,优化配方的接触角达153°、滚动角达到5°。经过相同落砂磨损试验后,增强后的复合涂层水珠接触角能在一定程度磨损后达到140°左右。可见,CeO2/PMMA/PVDF复合涂层具有良好的超疏水性能,碳纤维颗粒增强是提高该涂层耐磨性能的有效方法。

| Abstract: | Wear-resistance property acts as a key point to bio-inspired superhydrophobic surface for real application environment. CeO2 micro particles filled PMMA/PVDF composite coating was prepared by surface coating method in this study. In addition, carbon fiber particles were used to reinforce CeO2/PMMA/PVDF composite coating. The results revealed that the best water contact angle(WCA) of CeO2/PMMA/PVDF was 152°, the slide angle(SA) was 5°, the best WCA and SA of carbon particles reinforced CeO2/PMMA/PVDF were 153° and 5° respectively. After abrasion test, the WCA of CeO2/PMMA/PVDF decreased to 103°, and the SA increased to 20°.While carbon particle reinforced CeO2/PMMA/PVDF coating was able to maintain 140° after same abrasion test. It indicates that adding carbon particles is an effective method to improve wear-resistance of CeO2/PMMA/PVDF superhydrophobic composite coating and has prosperous potentiality towards mechanical robust water repellent coating. |
