摘要: 采用溶胶-凝胶法制备了鲜黄色的高反射TiO_2-CeO_2薄膜。研究了环境湿度和醋酸添加剂对薄膜形成的影响。研究表明:醋酸加入能显著提高薄膜质量,得到均匀透明的高质量薄膜;涂膜环境温湿度对薄膜质量有决定性作用。Abstract: Golden yellowish and high reflective TiO_2-CeO_2 coatings were prepared by thesol-gel dipping coating method.The effect of acetic acid and environment humidity of filmpreparation on the quality of coatings was studied in details.The results show that the highquality transparent and homogeneous film can not be obtained without the presence of HAc.The humidity of processing environment has significant influence on the coating quality.
