Embodiment 1
[0030] Dissolve 5g of acrylamide, 0.25g of N,N'-methylenebisacrylamide, and 0.5g of Tween in 94.25g of water, stir well to form a solution, and ensure that acrylamide and N,N'-methylenebisacrylamide are completely Dissolve to obtain a monomer solution; then weigh 60 g of the solution, add 40 g of mesophase pitch carbon microspheres with an average particle size ranging from 5 to 30 microns, and mix them uniformly by ball milling for 1 hour to obtain a stable slurry; then Add 0.2g ammonium persulfate and 0.1g N, N, N', N'-tetramethylethylenediamine to the slurry, mix it slightly with an electric mixer, and immediately inject the slurry into the mold of the formed tubular product. After 15 minutes at 60°C, the polymer monomers in the slurry form a gel network under the action of a crosslinking agent to obtain a tubular green body of mesophase pitch carbon microspheres; after demoulding the green body, put it in an air humidity of 85 % or more in a desiccator at room temperature ...
Embodiment 2
[0036] Dissolve 10g of acrylamide, 0.8g of N,N'-methylenebisacrylamide, and 0.5g of Tween in 98.7g of water, and stir to form a solution, ensuring that acrylamide and N,N'-methylenebisacrylamide are completely Dissolve to obtain a monomer solution; then weigh 40g of the solution, add 60g of mesophase pitch carbon microspheres with an average particle size range of 5-30 microns, and mix them uniformly by ball milling for 1 hour to obtain a stable slurry; then Add 0.1g ammonium persulfate and 0.05g N, N, N', N'-tetramethylethylenediamine to the slurry, mix it slightly with an electric mixer, and immediately inject the slurry into the mold of the formed tubular product. After 13 minutes at 70°C, the polymer monomer in the slurry forms a gel network under the action of the crosslinking agent to obtain a tubular green body of mesophase pitch carbon microspheres; % or more in a desiccator at room temperature until the volume of the green body is constant, then dried in air at 100°C ...
Embodiment 3
[0042] Dissolve 15g of acrylamide, 1.5g of N,N'-methylenebisacrylamide, and 4g of Tween in 79.5g of water, stir well to form a solution, and ensure that acrylamide and N,N'-methylenebisacrylamide are completely dissolved , to obtain a monomer solution; then weigh 20 g of the solution, add 80 g of mesophase pitch carbon microspheres with an average particle size range of 5-30 microns, and obtain a stable slurry after ball milling for 1 hour to obtain a stable slurry; Add 0.05g ammonium persulfate and 0.02g N, N, N', N'-tetramethylethylenediamine to the slurry, mix it slightly with an electric mixer, and immediately inject the slurry into the mold of the formed tubular product, at 80 After 10 minutes at ℃, the polymer monomer in the slurry forms a gel network under the action of the cross-linking agent, and obtains the mesophase pitch carbon microsphere tubular green; The above desiccator is kept at room temperature until the volume of the green body becomes constant, and then d...
