    摘要:

    本文利用溶膠-凝膠法，以硅烷偶聯(lián)劑γ-甲基丙烯酰氧基丙基三甲氧基硅烷（KH570）為改性劑，正硅酸四乙酯（TEOS）為前驅(qū)體，無(wú)水乙醇（EtOH）為溶劑，氨水為催化劑制備改性溶膠。并通過(guò)浸漬提拉法在BK7玻璃上鍍膜，獲得透光性?xún)?yōu)異且耐環(huán)境穩(wěn)定性良好的SiO2減反射薄膜。使用UV-Vis-NIR分光光度計(jì)、傅里葉變換紅外光譜儀（FTIR）、掃描電子顯微鏡（SEM）、接觸角測(cè)試儀等對(duì)薄膜的性能進(jìn)行測(cè)試。結(jié)果表明：當(dāng)TEOS與 KH570的摩爾比為5: 1時(shí)，薄膜樣品的透過(guò)率最高為99.50%，置于90%RH的濕度環(huán)境中60d后，薄膜的透過(guò)率基本不變，并表現(xiàn)出良好的耐環(huán)境穩(wěn)定性能。

    Abstract:

    The organic modified SiO2 sols were prepared by sol-gel method using γ-Methacryloxypropyl trimethoxy silane KH570 as modifier, tetraethylorthosilicate (TEOS) as precursor, and ammonia water as catalyst. Durable antireflective (AR) coatings were then deposited on the glass substrates by dip-coating method. The modified silica AR coatings were characterized by UV-Vis-NIR spectrometry, FTIR, SEM and water contact angle measurement, respectively. The results shown that the modified coating can achieve a high peak transmittance of 99.50% when the molar ratio of KH570 to TEOS was 1:5. After exposed in the humid environment with a relative humidity of 90% for 60 days, the transmittance of SiO2 coating modified by KH570 shown almost no change, which indicate that the environmental stability of the silica coating was greatly improved
