Abstract: The hydrogen bubble template method was used to successfully prepare a porous copper layer with a three-dimensional micro-nano structure. The effects of polyethylene glycol (PEG)and cetyl trimethyl ammonium bromide (CTAB)on the three-dimensional structure of porous copper (PCu)were studied. NaClO4 was embedded in the prepared PCu by solvent volatilization to form an embedded NaClO4 porous copper composite material. The results show that the porous copper layer adjusted by Cl-, PEG and CTAB has the smallest pore size and the most uniform distribution, and the overall porosity is about 94%. Its microscopic appearance shows that small holes are covered by large holes, and the hole wall is connected to the hole wall. 30 μL of 0.85 mol/L NaClO4 ethanol solution was embedded in PCu, and the sample was thermally analyzed by DSC. It was found that the decomposition temperature of NaClO4 dropped from 517 ℃ to 321 ℃, indicating that the three-dimensional micro-nanoporous copper exhibits excellent catalytic effect on the thermal decomposition of NaClO4, which can be used in the fields of propellants, explosives, and pyrotechnic materials.
