系统地研究了含氟聚酰胺酸的固化温度和固含量、摩擦条件、液晶材料的性能以及含氟二胺与不含氟二胺的物质的量比ｘ等因素对含氟聚酰亚胺表面排列性能的影响。研究结果表明，采用低聚酰胺酸固含量、低摩擦强度、较高的固化温度和较高的含氟二胺物质的量比可以得到具有较大预倾角的表面取向材料。 Fluorinated polyamic acid curing temperature and solid content, friction conditions, the properties of liquid crystal materials and the ratio of the amount of fluorine-containing diamine and non-fluorine-containing diamine x ratio were systematically studied on the fluorine-containing polyimide surface The effect of permutation performance. The results show that the surface orientation material with larger pretilt angle can be obtained by the ratio of low polyamic acid solid content, low frictional strength, high curing temperature and high content of fluorine-containing diamine.
