摘　　要：通过大气压脉冲级联放电(APPCD)等离子体的聚合交联作用,在涤纶织物表面快速制备兼具耐久性和自修复能力的超疏水涂层。深入研究不同等离子体放电源对涂层表面疏水性、耐久性及稳定性的影响。结果表明:APPCD等离子体制备的超疏水涂层表面水接触角可达163.2°,滚动角低至8.4°,样品经600次摩擦或250次水洗后仍可保持超疏水性;超疏水涂层表面弹性模量的变化是影响涂层机械牢度的主要原因;制备的超疏水涂层具有良好的可修复性,加热修复可使出现一定磨损的织物恢复疏水性。研究可为超疏水涂层的工业推广提供试验基础和技术支持。A superhydrophobic coating with good durability and self-healing ability was rapidly prepared on the surface of polyester fabric by polymerizing and crosslinking with atmospheric pressure pulsed cascade discharge(APPCD)plasma.The dependence of hydrophobicity,durability and stability of coating surface on different plasma sources were investigated in detail.The results show that the static water contact angle of the superhydrophobic coating prepared by APPCD plasma is up to 163.2°,and the dynamic water sliding angle is as low as 8.4°.The superhydrophobic properties of the coating can be maintained after 600 times of friction or 250 times of washing.It shows that the change of elasticity modulus on the coating surface is the main reason affecting the mechanical firmness fastness of the coating.The prepared superhydrophobic coating has good repairability.The broken fabric by friction can be restored by heating.This study can provide experimental basis and technical support for the industrial promotion of superhydrophobic coatings.
