摘　　要：为了改善普通玻璃的透过率,采用化学刻蚀法,在不同的温度和时间条件下,用不同浓度的NaOH溶液对普通玻璃进行刻蚀,得到了具有减反增透的疏松表面。通过扫描电子显微镜(SEM)观察玻璃刻蚀前后的形貌变化,使用原子力显微镜(AFM)测试了玻璃刻蚀前后的三维形貌和粗糙度,通过紫外可见近红外分光光度计和接触角测试仪,测试了刻蚀后玻璃的光学性质和润湿性。结果表明,当NaOH溶液的浓度为0.04mol·L^(-1)、刻蚀温度为30℃、刻蚀时间为50min时,刻蚀后的玻璃表面出现了一层疏松的膜层,粗糙度增大,透过率提高到92.23%,玻璃的光学性能得到了提高。In order to improve the transmittance of the ordinary glass,the chemical etching method was used to etch the ordinary glass with different concentrations of NaOH solution at different temperatures and time conditions,and the loose surface with reduced reflectivity was obtained.Change of morphology before and after glass etching was observed by scanning electron microscope(SEM),the 3D morphology and roughness of glass before and after etching were tested using atomic force microscope(AFM).The optical properties and wettability of the etched glass were tested by UV-visible near-infrared spectrophotometer and contact angle tester.The results showed that when the NaOH solution concentration was 0.04 mol/L,the etching temperature was 30℃,and the etching time was 50 minutes,the etching glass surface appeared a loose film layer,the roughness increased,the transmittance increased to 92.23%,and the optical performance of the glass was improved.
