The invention relates to a preparation method of a graphene polyaniline aerogel thermoelectric material and solves the technical problems that existing methods are uncontrollable in material component content and complex and have residual metal in the prepared material, and the prepared material is poor in stability, uneven in dispersing and non-ideal in thermoelectric performance. The preparation method includes: weighing aniline monomer, dispersing in HCl solution, adding oxidizing agent ammonium persulfate, and stirring while polymerizing under ice water bath to obtain polyaniline; evenly dispersing graphene oxide and the polyaniline into aqueous solution; adding ammonia water into the aqueous solution to performing temperature rising treatment to prepare graphene polyaniline hydrogel; performing freeze drying on the graphene polyaniline hydrogel to prepare graphene polyaniline aerogel; sufficiently grinding the graphene polyaniline aerogel, dispersing the ground graphene polyaniline aerogel and camphorsul
