[0029] The preparation method of the above-mentioned photodeformable azo polymer material also provided by the embodiment of the present invention includes the following steps:
[0030] 1) Ingredients: Dissolve the proportioning amount of acrylate azo monomer and initiator in dehydrated toluene ether to obtain a mixed solution, or mix the proportioning amount of acrylate type azo monomer, methyl methacrylate and The initiator is dissolved in dehydration toluene ether to obtain a mixed solution;
[0031] 2) Polymerization: Add the mixed solution into a reaction vessel and stir to dissolve it, and then pass argon gas for 5 to 30 minutes at -2 to 2°C to remove oxygen, then heat to 68 to 73°C, and react for 46 to 50 hours;
[0032] 3) Washing and drying: After cooling to room temperature, settle in methanol, then wash with formaldehyde at 40-50°C for 4-7 times, transfer to a vacuum oven and dry to constant weight to obtain photodeformable azo polymer Material.
