以电化学阳极氧化法制备的TiO2纳米管阵列为基底,分别通过电化学沉积法、化学还原法和浸渍法制备出Ag修饰的TiO2纳米管阵列,采用XRD、FESEM和UV-Vis等测试手段对样品的组成、结构及形貌等进行表征.以气相苯为降解物,对样品进行光催化活性测试.结果表明:与其他两种方法相比,化学还原法使得Ag纳米颗粒均匀分布在TiO2纳米管阵列的表面,并表现出更好的光催化降解气相苯的能力.

In order to realize the potential of composite materials, it is imperative to develop a manufacturing process, to understand the microstructures, and to assess the structural performance of the composite. The braided-pultrusion process, which combines the pultrusion process with the braiding technology, has been developed by utilizing a novel resin impregnation device. The goal of the development is to achieve both costeffectiveness and performance of the composite. The tubular composites of diameter 5.3 mm have been produced using Kevlar 49 fiber and polyester resin. In order to assess the mechanical performance of the composites, an analytical method for predicting the elastic constants has been developed. The analysis includes the geometric model of a unit cell, coordinate transformation, and averaging of stiffness and compliance constants of the constituent materials. The analytic predictions compared favorably with experimental results.
