摘要

为获得适用于光伏组件表面的二氧化硅（SiO2）超疏水薄膜

采用改进的Stober法制备MTES/TEOS杂化溶胶

并添加不同质量的HMDS进行疏水改性

最终通过浸渍法制备得到SiO2薄膜。针对制备所得薄膜

开展形貌结构、光学性能、表面性质和自清洁性能测试

同时进行薄膜的人工加速老化试验并测试得到薄膜性能的变化情况。结果表明

当HMDS/SiO2=3时

薄膜透光率为92.30%

水接触角可达165.28°

表面能仅为1.06 mJ/m2

自清洁效果优异

1500 h的光老化及高温老化造成的透光率和水接触角的变化程度小于5%。薄膜的综合性能满足光伏组件表面的应用需求

在光伏领域的应用前景广阔。

Abstract

To obtain SiO superhydrophobic thin films suitable for photovoltaic module surfaces

an improved Stober method was used to prepare MTES/TEOS hybrid sol and different amounts of HMDS were added for hydrophobic modification. Finally

SiO thin films were prepared by the impregnation method. Morphology and structure

optical properties

surface properties

and self-cleaning performance tests were conducted on the prepared thin film

and artificial accelerated aging tests were conducted on the films to obtain changes in their properties. The results showed that when HMDS/SiO=3

the transmittance of the film was 92.30%

the water contact angle could reach 165.28°

the surface energy was only 1.06 mJ/m

and the self-cleaning effect was excellent. The degree of change in transmittance and water contact angle caused by 1500 hours of photoaging and high-temperature aging was less than 5%. The comprehensive performance of the thin films meets the application requirements of photovoltaic module surfaces and has broad prospects in the field of photovoltaics.
