PET膜以其优异的性能在LCD领域得到了广泛应用，而功能性PET光学膜主要是通过在PET聚酯薄膜表面涂覆各种功能性涂层所得，因此PET型光学薄膜的涂层技术是光学膜的关键技术之**。从光学PET膜用涂层配方、涂层固化方式、涂布工艺和改善膜基材/涂层界面粘接强度的方法等方面，综述了PET型光学膜用涂层技术的**外研究进展。
光学**PET聚酯薄膜具有透光率高、雾度低、亮度高、不泛黄、附着力好、平整度好、无明暗纹、耐高温和紫外线照射、挺度佳、抗烧裂、不易破损等特点，近年来得到了广泛应用。特别是LCD生产领域中更是必不可少的原辅材料，例如液晶显示屏，**少可以用到7~8张具有不同功能的PET型光学膜（2张光扩散膜，1张增亮膜，2张相位差膜，1张防眩光膜，1张
屏蔽导电膜）。这些功能性PET型光学膜主要是通过在PET聚酯薄膜表面涂覆各种功能性涂层所得。因此，研制液晶显示领域中的PET型光学膜用各种功能性涂层是光学膜研究的重要方向之**。
**般要求光学膜基材应表观平整无缺陷、光泽度和透光率高、雾度低、涂布性能好等。
PET film with excellent performance in the field of LCD has been widely used, and the functional pet optical films is mainly through the PET polyester film was coated on the surface of various functions of coating income, so pet type optical film coating technology is one of the key technologies of optical film. In this paper, the research progress of coating technology for PET optical coatings is reviewed in this paper, from the aspects of coating formulation, coating curing method, coating technology and improving the bonding strength of the film substrate / coating interface, and so on.
Optical grade PET polyester film has a light transmittance characteristics of high, low haze, high brightness, yellowing, good adhesion, good flatness, and no dark lines, resistance to high temperature and ultraviolet radiation, quite good, burn crack resistance, not easy to damage, in recent years has been widely used. Especially LCD production areas is essential for raw and auxiliary materials, such as liquid crystal display, at least we can use 7-8 with different functional pet type optical film (2 pieces of light diffusion film, 1 Zhang Zengliang membrane and two phase difference film, 1 piece of anti glare film, a
Shielding conductive film. These functional PET type optical films are mainly obtained by coating a variety of functional coating on the surface of PET polyester film. Therefore, it is one of the important directions in the study of optical film to develop the PET type optical coatings in the field of liquid crystal display.

The general requirements of the optical film substrate should be a smooth surface without defects, gloss and high transmittance, low fog, good coating performance, etc..
