Interfacial structures of block and graft copolymers with lamellar microphase-separated structures

Abstract:

Chain conformations of A-polymers of BAB two-component triblock and ABB graft copolymers, composed of polystyrene (= A) and poly(2-vinylpyridine) (= B), with lamellar microphase-separated structures were investigated by small-angle neutron scattering (SANS), and interfacial thicknesses of AB diblock and BAB triblock copolymers were compared by using neutron reflectivity (NR). The middle A-block of BAB triblock copolymer has preferentially `loop' conformation when the volume fraction, φA, of A...
