Embodiment 1
[0077](1) Measure 500ml of graphene oxide aqueous dispersion (JCGO-95-1-2.6-W, 10mg / ml, Nanjing Jicang Nano Technology Co., Ltd.) in a beaker;
[0078] (2) Take 2g of the porous skeleton made of phenolic resin (phenolic foam, average pore size 300 μm, porosity 99%, Changshu Oasis Flower Foam Co., Ltd.) and soak it into the graphene oxide aqueous dispersion, so that the solution fully enters the pores of the porous skeleton;
[0079] (3) Take out the soaked porous material, put it in a stainless steel tray, heat it in an oven at 180°C for 1 hour, dry it and pre-reduce it;
[0080] (4) Put the dried porous material into a household microwave oven (700w) for high-heat microwave treatment for 2 minutes, the pre-reduced graphene oxide is reduced to graphene, and the phenolic resin skeleton is carbonized into a carbon skeleton (average pore size 200 μm, porosity 99%) , to obtain a graphene-loaded carbon porous framework porous composite material that generates arcs in microwaves, an...
Embodiment 2
[0082] (1) Measure 500ml of carbon nanotube dispersion (XFWDM, 100mg / ml, Nanjing Xianfeng Nano Material Technology Co., Ltd.) into a beaker;
[0083] (2) Take 2 g of porous skeleton made of phenolic resin (phenolic foam, average pore size 200 μm, porosity 99%, Changshu Oasis Flower Foam Co., Ltd.) and soak it into the carbon nanotube dispersion, so that the carbon nanotube dispersion can fully enter the porous skeleton the tunnel;
[0084] (3) Take out the soaked porous material, place it in a stainless steel tray, heat it in an oven at 80°C for 5 hours, and dry it;
[0085] (4) Put the dried porous material into a tube furnace, and carbonize it at 800° C. for 1 h under a nitrogen atmosphere to obtain a porous composite material (the average pore diameter of the carbon skeleton is 140 μm and the pores are rate of 99%), carbon nanotubes accounted for 30% of the total mass of the porous composite material.
Embodiment 3
[0087] (1) Measure 500ml of carbon nanotube dispersion (XFWDM, 100mg / ml, Nanjing Xianfeng Nano Material Technology Co., Ltd.) into a beaker;
[0088] (2) Take 5 g of silicate fiber cotton-like porous skeleton (average pore diameter 150 μm, porosity 90%, Shandong Luyang Energy Saving Materials Co., Ltd.) soaked in the carbon nanotube dispersion, extruded several times to make the dispersion The liquid fully enters the pores of the porous framework;
[0089] (3) Take out the soaked porous material, put it in a stainless steel tray, place it in a 150° C. oven and heat it for 2 hours, and dry it to obtain a porous composite material with a carbon nanotube loaded silicate fiber porous skeleton that generates an arc in the microwave, carbon The nanotube accounts for 10% of the total mass of the porous composite material.
