摘要

采用环境友好的MnO2-H2SO4-H2O 三元微蚀体系对聚丙烯塑料(PP)基体进行表面微蚀处理，以为后续的化学镀铜与电镀铜过程提供合理的条件。通过场发射扫描电镜(SEM)观察微蚀前后PP 基体表面形貌、表面接触角测量仪测定PP 基体表面亲水性能、90°剥离法测定PP 基体与镀铜膜间的粘接强度，分析微蚀处理对PP 基体表面形貌、亲水性和粘接强度的影响，确定PP 基体合理的微蚀处理条件。研究结果表明:在80 ℃的微蚀温度、微蚀液MnO2 含量80 g/L、VH2SO4 ∶VH2O ＝3.0 ∶1.0、微蚀时间100 min 的条件下PP 基体的表面微蚀效果较好。在微蚀温度为80 ℃时微蚀处理后，PP 基体表面接触角由91.7°降低为62.6°，亲水性得到改善，并且PP 基体表面出现了分布均匀、致密的微小孔洞；铜镀层与PP 基体之间的粘接强度达到3.5 N/cm，粘接强度明显提高。因此，MnO2-H2SO4-H2O 是一种有效的、环境友好的聚丙烯塑料表面微蚀体系。

Abstract

The environmentally friendly ternary microetching system of MnO2-H2SO4-H2O was employed to microetch the surface of polypropylene plastic (PP) matrix， in order to provide reasonable conditions for subsequent electroless copper plating and electrocoppering. The surface morphology of PP matrix before and after microetching was observed by field emission scanning electron microscope (SEM)， the hydrophilicity of PP matrix surface was measured by surface contact angle meter， and the adhesive strength between PP matrix and copper coating film was measured by 90 ° peel method. Furthermore， the influence of microetching treatment on the surface morphology， hydrophilicity and adhesive strength of PP matrix was analyzed to determine the reasonable microetching treatment conditions of PP matrix. Results showed that under the conditions of a microetching temperature of 80 ℃， a MnO2 content in microetching solution of 80 g/L， VH2SO4 ∶VH2O ＝3.0 ∶1.0， and a microetching time of 100 min， the surface microetching effect of PP matrix was good. After a microetching at a temperature of 80 oC， the surface contact angle of PP matrix was reduced from 91.7° to 62.6° and the surface hydrophilicity was improved；many uniform and compact micropores appeared on the surface of PP matrix； and the adhesive strength between the copper coating and PP matrix reached 3.5 N/cm， indicating that the adhesive strength was significantly improved. Therefore， the MnO2-H2SO4-H2O system was an environmentally friendly effective microetching system for the PP surface.
