Abstract: The invention relates to a method for producing a polymer master batch and a polymer composition, wherein the method comprises providing at least one monomer capable of forming a poly(hydroxy carboxylic acid), providing a graphene nano-filler, mixing the monomer and the graphene nano-filler and letting the monomer polymerize in the presence of the graphene nano-filler. The polymer together with the graphene nano-filler is further blended with another polymer to form a polymer composite. The invention also relates to a polymer composition with graphene nano-filler and a composite material comprising a polymer composite with graphene nano-fillers.
