The invention relates to a method for the production of polyoxadiazole composites made of polyoxadiazole homopolymers and/or copolymers by means of a, preferably direct, polycondensation reaction of A-A (hydrazine and/or its derivates) monomers and B-B (dicarboxylic acid and/or its derivates) monomers with a filler in polyphosphoric acid with the following steps: a) the filler is functionalized in the polyphosphoric acid through heating of the mixture, preferably under a gas atmosphere, b) hydrazine and/or its derivates and at least one dicarboxylic acid and/or its derivates are mixed with the mixture process step a) into a solution, c) the solution from process step b) is heated, preferably under an inert atmosphere, and d) the polyoxadiazole composites are precipitated in a solution and in particular neutralized. Moreover, the invention relates to polyoxadiazole composites and the use of polyoxadiazole composites.
