[0027] Example 1
[0028] like figure 1 As shown in the figure, the nano-copper powder is prepared according to the following steps in this example: a mixture of copper nitrate and graphite with a molar ratio of 1:1 is used as a raw material; 50 g of the above-mentioned raw materials are added to 100 ml of acrylamide (AM) with a concentration of 20 wt.% Organic monomers and N,N-methylenebisacrylamide (MBAM) cross-linking agent (wherein the mass ratio of organic monomer to cross-linking agent is m (AM) :m (MBAM) = 20:1) in the organic monomer solution, after 24h ball milling to obtain a suspension; 2.5ml of catalyst tetramethylethylenediamine and 1ml of saturated solution of ammonium persulfate initiator (1.5wt%) were added to the suspension, And placed in a constant temperature water bath at 80 °C for 1 h to obtain a wet gel; the wet gel was dried and dehydrated at 120 °C in a blast oven for 3 h to obtain a dry gel; the dry gel was calcined at a temperature of 300 °C 3h, ob...
