摘要

在本研究中,采用简单的一步溶胶-凝胶法合成了基于sio2的玻璃基超亲水防雾涂层。该工艺首先制备Si(OH)4溶胶,然后在溶胶中加入SiO2纳米粒子形成涂层溶液。研究了Si(OH)4溶胶和SiO2纳米颗粒含量对涂层性能的影响。它们的含量对涂层的亲水性和表面形貌等性能有显著影响。最佳涂层的水接触角约为3.4°。此外,蒸汽试验和冷冻试验表明,最佳的超亲水性涂层具有良好的防雾性能和足够的机械强度。与其他在玻璃基板上制备防雾涂层的技术相比,本研究开发的溶胶-凝胶基工艺不需要昂贵的设备,加工时间大大缩短。因此,该技术在涂料工业领域具有很大的应用潜力。

Robust superhydrophilic antifogging coatings by a facile sol–gel method

In this study, a simple one-step sol–gel process was applied to synthesize SiO2-based superhydrophilic antifogging coatings on glass substrates. In this process, Si(OH)4 sol was first prepared and then SiO2 nanoparticles were added to the sol to form coating solutions. The influence of both the Si(OH)4 sol and SiO2 nanoparticle contents on the coating properties was investigated. Their contents have significant effects on the coatings’ properties, including hydrophilicity and surface morphology. The water contact angle of the optimum coating is about 3.4°. Besides, as revealed by the steam test and freeze test, the optimum superhydrophilic coating demonstrates good antifogging properties and an adequate level of mechanical strength as well. Compared to other techniques used to fabricate antifogging coating on glass substrate, the sol–gel-based process developed in this study requires no expensive equipment, and the processing time is largely shortened. Thus, such technique has great potential applications in the field of coating industry.
