摘要

【目的】针对超疏水涂层在防腐阻垢过程中表面气膜易流失、长效稳定性差,导致防腐阻垢性能衰减、服役耐久性不足的问题。【方法】采用水热法合成花状结构纳米 ZnO粒子,经羟基氟硅油疏水改性后,以喷涂法制备超疏水聚偏氟乙烯(PVDF)/氟化 ZnO涂层,再通过浸渍羟基氟硅油,得到超滑涂层。通过扫描电子显微镜、接触角测量仪、电化学工作站等,系统分析涂层的润湿性、耐磨性、化学稳定性、耐腐蚀性及阻垢性能。【结果】涂覆羟基氟硅油制得的超滑涂层表面水接触角为(132. 9±2. 1)°,滑动角为(6. 8±0. 3)°。制备的超滑涂层表面腐蚀电流(Icorr)为 2. 81×10-11 A/cm2,腐蚀电位(Ecorr)为-0. 32 V。此外,在 0. 01 mol/L Ca2+模拟结垢溶液中进行 7d动态测试,超滑涂层表面 CaCO3结垢量仅 3. 3 mg/cm2。【结论】该涂层具备良好的力学性能、化学稳定性,展现出优异的防腐阻垢效果,为工业金属材料的腐蚀与结垢问题提供了有效解决途径。

Abstract

[Objective]To address the issues of superhydrophobic coating is prone to loss and thecoating exhibits poor long-term stability under harsh conditions,leading to the attenuation of anti-corrosion and anti-scaling performance and insufficient service durability.[Methods]In this study,a hydrothermal method was adopted to synthesize flower-like structured nano-ZnO particles,which were subsequently subjected to hydrophobic modification with hydroxyfluorosilicone oil. The superhydrophobic coating was fabricated via a spray-coating technique,and then the coating was impregnated with hydroxyfluorosilicone oil to form a super-slippery surface. Scanning electron microscope,contact angle measurement instrument,electrochemical workstation were used to characterize the wettability,wear resistance,chemical stability,corrosion resistance,and anti-scalingperformance of the coating.[Results]The super-slippery surface prepared by coating hydroxyfluorosilicone oil exhibits a water contact angle(WCA)of(132. 9±2. 1)° and a sliding angle of(6. 8±0. 3)° . The corrosion current density(Icorr)of the prepared super-slippery coating was 2. 81×10-11 A/cm2,and the corrosion potential(Ecorr) was -0. 32 V. Furthermore,after dynamic simulated scaling test in a 0. 01 mol/L Ca2+ solution for 7 days,the CaCO3 scaling amount on the surface of the super-slippery coating was only 3. 3 mg/cm2.[Conclusion]The coating possesses good mechanical properties and chemical stability,and exhibits excellent anti-corrosion and anti-scaling effects,providing an effective solution to the corrosion and scaling issues of industrial metal materials.
