Embodiment 1
[0025] A method for preparing a photofunctional polymer material, comprising the following steps:
[0026] Step 1: Weigh 1kg of vitamin B6 and dissolve it in 11.5L of water to make a vitamin B6 aqueous solution, and add the vitamin B6 aqueous solution into the reaction vessel, then add 630g of acrylamide to it, mix well, heat up to 60°C, and pour into the reaction vessel Add 1.21kg of toluene diisocyanate to the mixture, react at constant temperature for 2 hours, then lower it to room temperature for evaporative crystallization, and obtain unsaturated pyridine monomer;
[0027] In the second step, add 1kg of the unsaturated pyridine monomer prepared in the first step into 8L ethanol solution, disperse evenly at room temperature, then add 870g of europium chloride hexahydrate to it, ultrasonically disperse for 15 hours at room temperature, and then filter and wash , to obtain unsaturated europium complex monomer;
[0028] In the third step, 1 kg of the unsaturated europium com...
