the preparation method of the porous polydimethylsiloxane comprises the following steps: taking polydimethylsiloxane, uniformly stirring and mixing the polydimethylsiloxane and an ethoxylated polyethyleneimine solution according to the proportion of 1g:2-4 mu L, and vacuumizing until the solution is completely volatilized, thus obtaining porous polydimethylsiloxane;
the porosity of the porous polydimethylsiloxane is 60-75%, the particle size of the graphene powder is 10-500nm, and the mass ratio of the tetradecyl trimethyl ammonium chloride powder to the graphene powder is 1:1.
2. The radiation protective metal blend fiber of claim 1 wherein said vacuum is applied at 60-70 ℃ and 0.1-0.3 atmospheres.
3. The radiation protection metal blend fiber of claim 1, wherein the fiber body is blended from nylon fibers and polyester fibers.
4. A method of making the radiation protected metal blend fiber of claim 1, comprising the steps of:
(1) Obtaining a fiber body through blending of various fibers;
(2) Uniformly mixing porous polydimethylsiloxane, glycol diethyl ether acetate, tetradecyl trimethyl ammonium chloride powder, graphene powder, silicon carbide and protein powder according to a proportion, and performing ultrasonic dispersion for 40-60min under the power of 200-400W to obtain slurry;
(3) And (3) immersing the fiber body in the slurry, controlling the temperature of the slurry to be 60-70 ℃, immersing for 24-36h, taking out the fiber body, and naturally airing to obtain the radiation-proof metal blend fiber.
