摘要: 本实验通过一锅、两步法制备改性酚醛树脂.首先利用环氧酚醛树脂F-44与二甲胺反应,得到叔胺化酚醛树脂,叔胺化树脂被双氧水氧化后得到最终目标产物,即含强极性氧化叔胺基团的酚醛树脂.实验表明,该新型树脂易溶于水和一些强极性溶剂,如四氢呋喃、乙二醇独甲醚和N,N-二甲基甲酰胺等.在热的作用下,树脂能够分解并失去水溶性,但仍可溶于一些有机溶剂.由该树脂与830 nm激光增感染料匹配使用,树脂体系对红外光敏感,并能够通过中性水显影得到较为清晰的阴图型图像,表明该树脂有望用于免化学处理热敏激光成像领域.

Abstract: Modified phenolic resin was prepared through a two-step one pot method.First,Epoxy phenolic resin,F-44,was reacted with dimethylamine to give tertamine phenolic resin.Then,tertamine phenolic resin was oxidized with hydrogen peroxide to afford the final product,oxidized tertamine phenolic resin,which had strongly polar oxidized tertamine groups.This new resin was easily dissolved in water and some polar organic solvents such as tetrahydrofuran,2-methoxyethanol and N,N-dimethylformamide,etc.The resin became aqueous insoluble when treated at high temperature such as 160℃,but still remained soluble in organic solvents.When an IR dye with maximal absorption at 830 nm was incorporated into the film,it became sensitive to IR laser emitting at 830 nm and gave negative image after exposed by IR laser and developed by neutral water.This showed that the new resin could find uses in chemical-free thermal laser imaging applications.

Key words: epoxy phenolic resin, oxidized tertamine, water-soluble, IR laser imaging
