改善基板PI不沾的方法及PI液
摘要：
本发明提供一种改善基板PI不沾的方法及PI液，该改善基板PI不沾的方法包括如下步骤：步骤1、提供基板及PI液，PI液包括组分：PI分子及溶剂，该PI分子上带有疏水基团；步骤2、将PI液涂布于基板上，形成PI膜。该PI液包括组分：PI分子及溶剂，该PI分子上带有疏水基团，所述溶剂为N-甲基吡咯烷酮、γ-丁内酯、碳酸丁酯、或其混合溶剂。本发明的改善基板PI不沾的方法及PI液，PI液中的PI分子带有疏水基团，用该PI液涂布基板，疏水基团可与基板表面的有机物连接，增加PI液对基板表面的亲和性，改善PI不沾，提高涂布效果，提高基板的印刷品质。
摘要（英）：

The invention provides a method for improving PI non-stickness of a substrate and PI liquid. The method for improving the PI non-stickness of the substrate includes the following steps: step 1, providing a substrate and the PI liquid; and step 2, coating the PI liquid on the substrate and forming a PI film. The PI liquid comprises components: PI molecules and solvent, the PI molecules have hydrophobic groups, and the solvent is one of N-methyl pyrrolidone, gamma-butyrolactone and carbonic acid butyl ester or mixed solvent of the N-methyl pyrrolidone, the gamma-butyrolactone and the carbonic acid butyl ester. The PI molecules in the PI liquid have the hydrophobic groups, if the PI liquid is used for coating the substrate, the hydrophobic groups can be connected with organic matters on the surface of the substrate, affinity of the PI liquid on the surface of the substrate is improved, the PI non-stickness is improved, a coating effect is improved, and printing quality of the substrate is improved.
