摘　　要：该文基于光伏板静电除尘的应用需求,制备得到一种单壁碳纳米管透明导电薄膜。首先搭建人工加速光老化、盐雾老化、高温老化、高低温老化实验平台,开展单壁碳纳米管透明导电薄膜的老化实验,并进行薄膜的耐老化性能分析。然后搭建光伏板静电除尘实验平台,对该薄膜在静电除尘中的应用效果进行评价。实验结果表明,高温老化和高低温老化对单壁碳纳米管透明导电薄膜结构形貌和光电性能的影响较小,而经过2 000 h光老化和盐雾老化后,薄膜方阻分别上升至未老化时的14.6倍和28.7倍。盐雾老化造成部分导电薄膜从基底上脱落,使得静电除尘率由未老化时的98.35%下降至81.76%,而其他三种类型的老化不会对静电除尘效果造成明显影响。最后采用整合自回归移动平均模型预测单壁碳纳米管透明导电薄膜的品质因数和应用寿命。研究结果对单壁碳纳米管透明导电薄膜在以光伏玻璃外表面为代表的室外应用场景下的有效使用和寿命评估具有重要意义。In recent years,the use of transparent conductive film as the photovoltaic (PV) panel surface materials,while the high-voltage electrodes placed above the PV panel,which makes the dust particles charged and jump from the surface of the PV panel under the action of electrostatic force,to realize the PV panels to effectively remove the dust of the new electrostatic dust removal method has gradually become a hotspot in the research.Based on the application requirements of electrostatic dust removal of PV panels,single-walled carbon nanotubes (SWCNTs) transparent conductive films are prepared,and aging experiments of SWCNTs transparent conductive films are carried out on the experimental platforms of photoaging,salt-fog aging,high temperature aging,and high-low temperature aging for 2 000 h.The research results indicate that the types of aging that have the most significant effect on the transmittance and haze of the SWCNTs transparent conductive films are photoaging and salt-fog aging,respectively,with the transmittance of the films decreasing to 90.39%and the haze increasing to 4.98%after 2 000 h aging.The effect of high temperature aging and high-low temperature aging on the sheet resistance of the film is small,and the sheet resistance of the film after aging is 8.418×10~4?/□and 8.633×10~4?/□,respectively,whereas the sheet resistance of the film due to photoaging and salt-fog aging rise to 4.753×10~5?/□and 9.337×10~5?/□,respectively.In addition,both the water contact angle and the glycol contact angle of the SWCNTs transparent conductive films increase with increasing aging time.The structure and morphology of the SWCNTs transparent conductive films don’t change significantly during photoaging,high temperature aging,and high-low temperature aging,whereas salt-fog aging causes multi-area and large-area film detachment.From the application effect of aging film in electrostatic dust removal of PV panels,the rise of sheet resistance doesn’t significantly affect the dust removal effect,but the film det
