 Embodiment 2: The method for preparing an epoxy resin polymer with electrochromic properties of this embodiment is carried out according to the following steps:
 1. Synthesis of monomer
 a. Mix diaminotriphenylamine derivatives and p-hydroxybenzaldehyde in a molar ratio of 1:2~3 to obtain a mixture; b. The mixture obtained in step a and the solvent have a mass-volume ratio of 0.8~2.1g :100mL mix evenly to obtain the mixed solution, then under the protection of nitrogen, raise the temperature to 120°C~140°C, stir at 20~50rpm for 12h, when the solvent in the mixed solution evaporates to the original volume of the mixed solution At 1 / 4, stop stirring and collect the remaining 1 / 4 volume of liquid; c. Put the remaining 1 / 4 volume of liquid collected in step b into distilled water, let it stand for 6-12 hours, and then set the vacuum to 0.09MPa Carry out suction filtration under vacuum, collect the solid phase, put the collected solid phase into a vacuum oven, an...
