The invention discloses a preparation method of a polyaniline inverse opal/nano fiber felt composite film. The preparation method comprises the following steps: preparing a colloid crystal on a substrate through self-assembly of a polymer microsphere; inclining the substrate and the colloid crystal together and putting into a culture utensil; slowly adding deionized water into the culture utensil,gradually rising a water surface and stripping the colloid crystal from the substrate to enable the colloid crystal to be floated on the water surface; preparing an aniline solution, and adding ethanol of which the volume is 3 to 10 percent of that of water into the aniline solution; taking the colloid crystal in the culture utensil out by using the substrate and transferring the colloid crystalto the surface of the aniline solution; adding a ferric trichloride or ammonium persulfate solution, wherein the molar rate of the ferric trichloride or ammonium persulfate solution to aniline is (2to 1) to (20 to 1), into the
