The invention relates to a preparation method and application of a conducting film material, particularly a preparation method and application of a bacterial cellulose/polyaniline/carbon nanotube conducting film material. The method aims to solve the problems of complex preparation technique, high cost, poor stability and poor mechanical properties in the existing flexible electrode material. The method comprises the following steps: preparing a bacterial cellulose slurry; preparing a bacterial cellulose/polyaniline composite material solution, preparing a carbon nanotube water dispersion, carrying out vacuum filtration on the bacterial cellulose/polyaniline composite material solution to form a film, adding the carbon nanotube water dispersion, and continuing vacuum filtration and drying to obtain the bacterial cellulose/polyaniline/carbon nanotube conducting film material which is applicable to supercapacitors. The preparation method can implement large-scale production, and has the advantages of simple preparation technique and low cost. The conducting film material has favorable stability and mechanical properties. The prepared supercapacitor has favorable capacitive character. The bacterial cellulose/polyaniline/carbon nanotube conducting film material belongs to the technical field of nano materials.
