Abstract

The present invention discloses new materials elaborated upon organo-heteroatom (silicon or germanium) polymers (poly(amide-imide)s and poly(amide)s) and a metallic film, such as, but not limited to, copper, silver or gold, having the processability and malleability of a polymer and the structural, thermal, optical, electrical and other characteristics from the metals that it absorbs. The polymers of the invention have the capacity to incorporate, with covalent bonds, in coordinated and arranged form, the metals to its structure, generating a new macromolecular material. The invention is also related to a new method to prepare polymer-metallic nanoparticle hybrid materials, comprising the steps of a) providing a polymer solution dissolving the organo- heteroatom (silicon or germanium) polymer (poly(amide-imide)s or poly(amide)s) in an aprotic polar organic solvent; b) providing a metal film from the selected metal; c) dispersing the polymer solution by spin coating on the metal film; and d) simultaneous absorption, nano- encapsulation or incorporation of the metal into the polymer matrix..
