Embodiment 1
[0025] A method for preparing a methylated polythiophene electromagnetic material, comprising the following steps:
[0026] (1) Take 60 parts by weight of thiophene, add it to chloroform which is 6 times its weight, stir evenly, add 3 parts by weight of 3-aminopropyltriethoxysilane, raise the temperature to 45°C, and ultrasonically for 1 hour, Chloroform was removed by distillation to obtain an aminated monomer;
[0027] (2) Take the above-mentioned aminated monomer, add it into a hydrogen peroxide solution 10 times its weight, and stir evenly;
[0028] (3) Take 90 parts by weight of graphene, add it to 96% sulfuric acid solution that is 30 times its weight, stir evenly, add 50 parts by weight of potassium permanganate, stir at 25°C for 16 hours, filter, and remove the precipitate Washing with water, drying at room temperature, adding to the hydrogen peroxide solution of the aminated monomer, stirring for 1 hour, raising the temperature to 70°C, adding 6 parts by weight of ol...
Embodiment 2
[0035] A method for preparing a methylated polythiophene electromagnetic material, comprising the following steps:
[0036] (1) Take 70 parts by weight of thiophene, add it to 9 times its weight in chloroform, stir evenly, add 4 parts by weight of 3-aminopropyltriethoxysilane, raise the temperature to 50°C, and ultrasonically for 2 hours, Chloroform was removed by distillation to obtain an aminated monomer;
[0037] (2) Take the above-mentioned aminated monomer, add it into a hydrogen peroxide solution 14 times its weight, and stir evenly;
