在金属化之前，聚合物的湿化学前处理过程通常是在强酸浴中进行的，如铬、硫酸或高锰酸钾溶液。虽然该方法在工业应用中得到了广泛的应用，但它造成了不良的环境污染，并存在电镀产品的一致性和重复性等固有问题。本文介绍了一种利用P-25分散溶液中的光催化反应和水热法制备的二氧化钛溶胶对聚合物进行表面改性的新方法，以取代造成环境污染的湿法化学前处理工艺。用X射线光电子能谱(XPS)研究了表面的化学变化。用扫描电子显微镜(SEM)和原子力显微镜(AFM)对其形态变化进行分析。在聚合物化学镀铜前的表面改性阶段，利用光催化反应在二氧化钛颗粒的存在下进行表面改性，在不改变表面形貌的前提下，获得了良好的结合强度。
The wet-chemical preconditioning process of polymers prior to metallization is generally performed with a strong acid bath such as a chromic, sulfuric or potassium- permanganate solution. Although the method is widely used in industrial applications, it results in undesirably environmental pollution and has inherent problems of uniformity and reproducibility for plating products. In the present study, a novel surface modification of a polymer utilizing the photocatalytic reaction in a P-25 dispersed solution and TiO2sol prepared by a hydrothermal method was introduced to replace the wet-chemical pretreatment process which resulted in environmental pollution. Chemical changes in the surface were investigated with X-ray photoelectron spectroscopy (XPS). Analysis of the morphological changes was done by using scanning electron microscopy (SEM) and atomic force microscopy (AFM). The surface modification method using the photocatalytic reaction in the presence of TiO2particles resulted in excellent adhesion strength without a change of the surface morphology at the surface modification stage before electroless Cu plating for polymers.
