通过对玻璃纤维(GF)/环氧树脂(EP)(GF/EP)复合材料的设计与加工,制得具有不同润湿性能表面的GF/EP复合材料。结果表明:可以通过对GF/EP复合材料表面微观结构及表面化学成分的调控来实现GF/EP复合材料表面的亲水、疏水及超疏水性能,GF/EP复合材料超疏水表面的摩擦系数为0.08,磨损量为0.12%;相比GF/EP复合材料亲水表面来说,绿脓杆菌在GF/EP复合材料超疏水表面的黏附量下降了20%左右,白色念珠菌下降了80%左右。
Through the design and processing of glass fiber/epoxy resin (GF/EP) composites,GF/EP composites with different wetting properties were prepared and the influence of wetting property on the friction performance and microorganisms adhesion were investigated.The results showed that:the hydrophilicity,hydrophobicity and superhydrophobicity of GF/EP could be controlled by adjusting to the microstructure and chemical composition of GF/EP surface.The friction coefficient and wear loss were 0.08 and 0.12% respectively for superhydrophobic GF/EP.The amount of attachment decreased about 20% and about 80% for candida albicans and pseudomonas aeruginosa on superhydrophobic GF/EP,comparing to hydrophilic GF/EP.
