一种基底支撑聚合物薄膜黏流温度的测量方法
摘要：
本发明提供了一种基底支撑聚合物薄膜黏流温度的测量方法，首先将基底支撑聚合物薄膜加热至温度T并维持温度恒定；然后将测试液体置于所述维持温度恒定的聚合物薄膜表面，形成液滴，并记录放置时间；将聚合物薄膜冷却，除去聚合物薄膜表面的液滴，在所述除去液滴的聚合物薄膜表面的聚合物/液滴/空气三相线处形成润湿脊，测量润湿脊的高度；以所述润湿脊的高度h对所述聚合物薄膜的温度T作图，得到h～T关系曲线，当所述聚合物薄膜中聚合物的重均分子量大于其缠结分子量时，根据h～T关系曲线得到聚合物薄膜的黏流温度Tf。本发明提供的测量方法能够准确的测定基底支撑聚合物薄膜黏流温度，操作方法简单、成本低、适应性广。
摘要（英）：

The invention provides a measuring method for the viscous flow temperature of a substrate supporting polymer film. The measuring method comprises the steps that firstly, the substrate supporting polymer film is heated to the temperature T, and the temperature is maintained to be constant; secondly, test liquid is placed on the surface of the polymer film with the temperature maintained to be constant to form liquid drops, and the placing time is recorded; thirdly, the polymer film is cooled, the liquid drops on the surface of the polymer film are removed, wetting ridges are formed at the polymer/liquid drop/air three-phase lines on the surface of the polymer film with the liquid drops removed, and the heights of the wetting ridges are measured; a graph is made with the heights H of the wetting ridges to the temperature T of the polymer film, an h-T relation curve is obtained, and when the weight-average molecular weight of a polymer in the polymer film is larger than the entanglement molecular weight of the polymer, the viscous flow temperature Tf of the polymer film is obtained according to the h-T relation curve. By means of the measuring method, the viscous flow temperature of the substrate supporting polymer film can be accurately measured, the operation method is simple, cost is low, and adaptability is high.
