一种新型纳米稀土氧化物玻璃防雾剂的研究

Study on A Novel Nano Rare Earth Oxide Glass Antifogging Agent

利用硝酸-H2O2法制取纳米CeO2和La2O3颗粒。然后以乙醇和异丙醇为溶剂,乙二醇和甘油为添加剂,加入一定量的表面活性剂,以及纳米CeO2和La2O3颗粒,余量为水来制备防雾剂。该文所制备的防雾剂润湿效果很好,其接触角为3.75°,亲水性强,防雾效果好。

Nitric acid and H2O2 were used to obtain the nanocrystalline CeO2 and La2O3 solid.The alcohol and isopropanol were used as solvent,glycol and glycerol as additives,by adding some nanocrystalline CeO2 and La2O3 solid and surfactant,and some water as the stuff,the antifogging agent was prepared.The obtained antifogging agent was good in terms of wetting,antifogging and hydrophilcity effect,and its contact angle was 3.75 degree.
