Surface animation of polylacrylonatrile

The surface amination of poly(acrylonitrile) by ammonia plasma treatment has been studied.Furthermore, two other surface modification techniques have been investigated, the plasma chemical decomposition of an amino group containing chemical (tris-(2-aminoethyl)amine) onto the polymer surface and thesurface reduction by lithium aluminium hydride.The three different methods are compared with respect to the adhesion improve ment of the coatings onto the modified surfaces.The number of groups introduced on the surfaces has been determined by a wet chemical method.
