摘要：以电流体动力(EHD)诱导聚乙烯醇(PVA)薄膜表面微结构的形成为对象,研究了不同EHD工艺和氢氟酸刻蚀工艺对PVA薄膜微图案结构及玻璃表面微结构制备和光学性能的影响,提出了一种利用PVA微图案结构调控氢氟酸刻蚀玻璃表面制备光学微结构的新方法。结果表明,改变EHD诱导电压和PVA薄膜初始厚度可以得到区别化的PVA薄膜微图案,而改变氢氟酸浓度和刻蚀时间可以将微图案刻蚀到玻璃表面并在玻璃表面形成一系列不同的微结构;经处理后的玻璃表面较未使用PVA薄膜的玻璃具有更高的雾度和透射率。
In this study,a new strategy was proposed to fabricate various columnar microstructures on the glass surface through controlling the glass surface hydrofluoric acid etching process using the patterned poly(vinyl alcohol)(PVA)film.The electrohydrodynamic(EHD)technique was adopted to fabricate the cylindrical microstructures on the surface of the PVA film spin?coated on the glass surface.Followed by the hydrofluoric acid etching process,various primary mi?crostructures were fabricated on the glass surface to tune the optical properties.The results indicated that the changes in the EHD induced voltage and the initial thickness of the PVA film could lead to differentiated cylindrical micropatterns on the PVA film.Furthermore,the changes in the etching time and concentration of hydrofluoric acid could lead to a variety of columnar microstructures on the glass surface,which dominated the optical properties of glass such as haze and trans?mittance.With the results obtained from this work,the application range of PVA film patterning technology in the manu?facture of glass surface microstructures can be greatly expanded.
