CuO填充尼龙6复合材料的耐腐蚀性能研究

采用热压成型的方法制备了不同添加量的CuO/尼龙6 (PA6)复合材料,对复合材料的力学性能、显微组织和耐腐蚀性能和抗微生物附着的情况进行了实验研究,利用扫描电子显微镜对其腐蚀机理进行分析。结果表明,CuO质量分数介于5%～20%时,复合材料的拉伸强度有明显提高,质量分数为20%时填充效果最好,拉伸强度可以达到70MPa以上。复合材料在酸溶液中的铜离子析出情况与时间成一元二次方程的关系,并且CuO含量为20%的材料在稀盐酸中的铜离子浓度明显大于CuO含量为10%的复合材料。最后证明了CuO的填充对复合材料的抗生物附着的性能有显著的影响。

Research on Corrosion Resistance of CuO Filled Nylon 6 Composites

Different amounts of CuO and Nylon 6(PA6)composites were prepared by hot-press forming method.The mechanical properties,microstructure,corrosion resistance and antimicrobial adhesion of the composites were studied experimentally,and scanning electron microscope(SEM)was used to analyzes its corrosion mechanism.The results show that the tensile strength of the composites is significantly improved when CuO mass fraction is between 5%and 20%.The filling effect is best when the mass fraction is 20%,and the tensile strength can reach 70 MPa.The precipitation of copper ions in the acid solution is related to the quadratic equation of time,and the copper ion concentration of the material with 20%CuO content in dilute hydrochloric acid is significantly larger than that of the composite material with 10%CuO content.Finally,it was proved that the filling of CuO had a significant effect on the bio-adhesion properties of the composite.
