Description

technical field [0001] The invention relates to a polyamide film and its preparation method and application. Background technique [0002] Polymers containing triphenylamine can form cationic radicals under the action of an electric field, and are important raw materials for the preparation of charge transport materials, electroluminescent materials, and electrochromic materials, as well as organic dyes and pharmaceutical intermediates. Aromatic polyamides are high-performance polymers. They have good mechanical properties and electrochromic properties, and are expected to be used in optical storage, optical memory, optical computing, and optical limiting laser protection. However, the existing polyamides still have the problems of low solubility, difficulty in film formation and low photochromic response sensitivity, which need further research and improvement. The main solution is to introduce large groups on the main chain. On the other hand, by changing the chemical st...
