ABSTRACT:
The present invention is directed to a process for imparting adhesive-free adhesion characteristics (i) between two polymer films, (ii) between a polymer film and a polymer fiber, and (iii) between the surface of a polymer fiber or film and a polymer matrix. The adhesive-free adhesion properties of the polymer film and fiber surfaces are introduced through a method for modification of a pre-activated polymer surface via near-UV-light induced or thermally-induced surface graft copolymerization with a functional monomer. The adhesive-free adhesion may be a result of dispersive interaction, chain entanglement, electrostatic interaction, ionic interaction, acid/base interaction, H-bonding and/or covalent bonding of the resulting grafted functional polymer(s) at the interface, or of the resulting grafted functional polymer and the polymer matrix.
