The invention discloses a network-like polythiophene nanowire electrochromic material. The network-like polythiophene nanowire electrochromic material has a network-like structure, the diameter of grid sides ranges from 20 nm to 60 nm, and reversible change between blue and purple can be achieved. A preparing method of the network-like polythiophene nanowire electrochromic material comprises the steps that 3,4-ethylenedioxythiophene monomers with a certain concentration and lithium perchlorate with a certain concentration are added into an ethanol solution, polymerization is carried out with an electrochemical workstation and a three-electrode system under a certain potential, a poly(3,4-ethylenedioxythiophene) film is made to grow on ITO conductive glass serving as a working electrode, and thus the network-like polythiophene nanowire electrochromic material is prepared. Grids of the network-like polythiophene nanowire electrochromic material are compact and are distributed evenly, the network-like film has a
