摘要聚酰亚胺（PI）是指主链上含有酰亚胺环（-CO-N-CO-）的一类聚合物，其中以含有酞酰亚胺结构的聚合物最为重要。聚酰亚胺作为一种特种工程材料，已广泛应用在航空、航天、微电子、纳米、液晶、分离膜、激光等领域。聚酰亚胺，因其在性能和合成方面的突出特点，不论是作为结构材料或是作为功能性材料，其巨大的应用前景已经得到充分的认识，被称为是"解决问题的能手"。因此本论文选择聚酰亚胺为基底，利用溶胶-凝胶法，向其杂化一定比例的无机元素并配合旋转涂程序制膜于玻璃上，经热处理程序制备具有低辐射与阳光控制功能的多功能节能玻璃用薄膜材料PI-SiO2，PI-VO2，PI-SiO2-VO2三种复合薄膜。即镀有该节能薄膜的玻璃窗，具有冬季加热保温，夏季隔热的节能效果。本论文亦研究了所制备薄膜的性能。9855

The Preparation of Multifunctional Energy-saving thin film used on glass
Abstract
Polyimide (PI) is the main chain containing imides ring (-CO-N-CO-) for a class of polymers, which contain ophthalmic imides structure is the most important polymer. Polyimide is a kind of special engineering material, which has been widely used in aviation, aerospace, microelectronics, nanotechnology, LCD, separation membranes, laser fields. Polyimide, because of its outstanding characteristics of property and synthesis, both as a structural material and as a functional material, its great application prospect has been fully understood, is called "the problem solver". The polyimide as substrate, using sol-gel method, the hybrid proportional to inorganic elements and is matched with a rotary coating procedures for film on the glass, the heat treatment multi-purpose energy-saving glass program prepared with low radiation and solar control film for material PI-SiO2, PI-VO2, PI-SiO2-VO2 three composite films. That is coated with a glass window of the energy-saving film, with the winter heating, summer heat insulation energy saving effect. This paper also studies the performance of thin film.
