摘要
随着光伏产业的高速发展,与之配套使用的减反射玻璃重新进入了研究者们的视野.本文采用湿化学二步刻蚀法制备了具有减反射性能的Na2O-CaO-SiO2平板玻璃,采用分光光度计、扫描电子显微镜、原子力显微镜和X射线能谱仪等测试样品的透过率、表面形貌和断面膜层厚度、表面化学成分、耐酸性和硬度,研究了反应温度和反应时间、玻璃膜层结构与透过率的关系.通过使用弱碱性的混合盐溶液对Na2O-CaO-SiO2玻璃表面进行化学刻蚀,使玻璃表面Si—O键断裂,在玻璃表面形成纳米膜层结构,当膜层厚度达到一定厚度时,一定波长的光在玻璃表面发生相消干涉,透过率最高可达到97.8％,刻蚀前后玻璃成分基本无变化,铅笔硬度达到3H.
Abstract
With the rapid development of photovoltaic industry in recent years,anti-reflective glass comes into researchers'sight.This article uses two-step chemical etching method to prepare Na2O-CaO-SiO2 flat glass with anti-reflective properties.The transmittance,surface morphology,cross-section film thickness,surface chemical composition,acid resistance and hardness of samples were measured by spectrophotometer,scanning electron microscope,atomic force microscope and X-ray energy spectrometer.The relationship between reaction temperature,reaction time,glass film structure and transmittance were studied.The Si—O bonds on Na2O-CaO-SiO2 flat glass surface were broken by etching glass surface with weakly alkaline mixed salt solution,and a nano film structure is formed on the surface of glass.When the corrosion reaches a certain thickness,destructive interference of a certain wavelength of light occurs on glass surface,with a maximum transmittance of 97.8％.The glass composition remains basically unchanged before and after etching,and the pencil hardness reaches 3H.
