【摘要】 用中性溶液法在硼硅酸盐玻璃片上制备了低反射涂层,并在Na2HPO4和AlCl3组成的浸涂液中于95°C条件下恒温浸泡6 h,结果表明硼硅酸盐玻璃片在400~900 nm波长内的平均透过率由原来的91.97%提高至98.97%,平均反射率降低至1.41%,中心波长处反射率仅为0.85%。为提高涂膜的耐候性,以低质量分数的十三氟辛基三乙氧基硅烷(FAS)对涂层样品进行表面处理。抗酸性测试结果表明:经w=0.3%的FAS溶液处理后的低反射涂层在1 mol/L盐酸中连续侵蚀7 d后,透过率平均值仍达到95.44%。说明经过FAS处理后,低反射涂层的耐候性能得到提高,使用寿命延长。更多还原

【Abstract】 The antireflective（AR） film on borosilicate glass was prepared by a neutral solution etching process in this work.After immersing in the neutral solution composed of Na₂HPO₄ and AlCl₃ at 95（°C） for 6 h,the average optical transmittance（400-900 nm） of the glass increased from 91.97% to 98.97%,the average reflectivity decreased to 1.41% and the reflectivity was only 0.85% at center wavelength.In order to improve the weatherability of the sample,the coated sample was retreated by perfluorooctyltriethoxysilane（FAS） at a low concentration.The resistant test of the sample etching in（1 mol/L） HCl solution for 7 d showed that the average optical transmittance（400-900 nm） of the glass retreated by FAS was still 95.44%.It means that the weatherability of the coated samples is improved by retreating with FAS and the using life of a AR film on borosilicate glass can be prolonged.更多还原
