摘　　要：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。The influences of the curing temperatures and solid contents of the fluorated polyamic acid, rubbing conditions, properties of the liquid crystals and molar ratios of the fluorated diamine on the surface alignment properties of the fluorated polyimide were studied. The alignment agent which has larger pretilt angle(5-7°) was obtained by using lower solid content of the polyamic acid, lower rubbing intensity, higher curing temperture and molar ratio of the fluorated diamine.
