摘要
研究了具备光催化性能和超亲水性能的TiO_2镀膜材料的自清洁作用机理。分别测试不同加水量、涂膜层数和水解时温度对TiO_2镀膜材料性能的影响,优化了传统的溶胶-凝胶镀膜材料的制备方法。基于TiO_2镀膜材料,分析掺入HPC、Si和钒,并分析掺杂后镀膜材料特性的变化。其结果表明,HPC改性导致TiO_2薄膜颗粒纳米化和表面粗糙度增加,使得镀膜材料的光催化性能得到提高,而掺入钒后,使得TiO_2薄膜保持长久的超亲水性。通过实验分析得出,在户外环境下,覆盖掺钒的TiO_2镀膜玻璃和纯TiO_2玻璃光伏组件相比于普通组件能够提升5.87%和2.78%的输出功率。可见这种基于TiO_2的混合镀膜光伏玻璃技术有望在将来的生产中得到具体应用。
The photocatalytic ability and super hydrophilic ability of TiO2 coating materials for self-cleaning mechanism was investigated. The effects of amount of water, coating layers and hydrolysis temperature on TiO2 coating material were tested,and the traditional sol-gel coating method was optimized. Based on the TiO2 coating material, HPC, Si and vanadium were mixed respectively, and the change of characteristics for coating materials was analyzed. The results indicate that the mixed HPC cause the nano grain and surface rough of TiO2 coating materials, increasing the photocatalytic ability, while the mixed vanadium can keep super hydrophilic ability of TiO2. Under the outdoor condition, compared with current PV panels, the mix vanadium and pure TiO2 glasses PV panels increase the output power by 5.87% and 2.78%. Thus the photovoltaic glasses mixed coating material based on TiO2 is applicable in the future.
