The present invention relates to a preparation method of a polymer composition comprising wood powder which is an environment-friendly material. More particularly, the preparation method of a polymer composition in the present invention comprises the steps of: preparing graphene-adhered wood powder by mixing a dispersion solution of graphene with wood powder and drying the mixture; and melting and extruding a mixture including a thermoplastic resin and the graphene-adhered wood powder. The polymer composition according to the present invention is confirmed to exhibit 18% and 13% increase of impact strength and tensile strength, respectively, in comparison to a polymer composition including wood powder without graphene. In comparison, a composition which is molten and extruded by simply mixing a thermoplastic resin, wood powder, and graphene without preparing the graphene-adhered wood powder exhibited only 5% and 3.7% increase of impact strength and tensile strength, respectively. |
