ABSTRACT:
A surface graft material including a substrate and a surface graft polymer chain, wherein the surface graft polymer chain includes a photocleavable moiety at one of its terminals, and the surface graft polymer chain is directly bonded to a surface of the substrate by a covalent bond between the photocleavable moiety and the substrate. A graft pattern formation method comprising exposing the graft material to cleave the photocleavable moiety in the exposed area, and removing the graft polymer chain from the exposed are to form a surface graft polymer chain pattern. A conductive pattern material and a metal particle pattern material using the graft pattern.
