摘要:
通过匀质机分散氧化石墨烯(GO)在水性聚氨酯(WPU)基体中,并采用刮膜工艺在镜面不锈钢板上制备GO/WPU光感薄膜。随后将紫外线(UV)吸收剂分散在清漆中,在GO/WPU光感薄膜表面形成抗紫外线清漆涂层,以系统考察涂层厚度及紫外线吸收剂种类对薄膜光感性能的影响。结果表明:GO可以均匀地分散在WPU基体中;相比于GO/WPU光感薄膜,采用UV-531作为紫外线吸收剂并控制涂层厚度为0.2 mm时,薄膜的光感速率得到显著改善,光感变化时间明显延缓;抗紫外线涂层显著提升了薄膜的疏水性,其水接触角达到80.27°。
Abstract:
Graphene oxide(GO)was dispersed in a waterborne polyurethane(WPU)matrix by a homogenizer, and a GO/WPU photosensitive film was prepared on a mirror stainless steel plate adopting the blade coating process. Subsequently, ultraviolet(UV)absorbers were dispersed in varnish to form an anti-UV varnish coating on the surface of the GO/WPU photosensitive film, in order to systematically investigate the effects of coating thickness and the types of UV absorbers on the film photosensitive properties. The results show that GO could be uniformly dispersed in the WPU matrix. Compared with the GO/WPU photosensitive film, when UV-531 was used as the UV absorber and the coating thickness was controlled at 0.2 mm, the photosensitive rate of the film was improved significantly, and the photosensitive change time was delayed obviously. The anti-UV coating significantly enhanced the hydrophobicity of the film with its water contact angle reaching 80.27°.
