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.

A surface graft material including a substrate and a surface graft polymer chain, wherein the surface graft polymer chain includes a polymer chain, a photocleavable moiety and a substrate-bonding group in this order, and the surface graft polymer chain is directly bonded to a surface of the substrate by a covalent bond between the substrate-bonding group and the substrate.
A graft pattern formation method comprising:
- exposing a surface graft material including a substrate and a surface graft polymer which includes a polymer chain, a photocleavable moiety and a substrate-bonding group in this order, so as to cleave the photocleavable moiety in exposed areas;
- and
- removing the surface graft polymer chain from the exposed areas to form a surface graft polymer chain pattern,
- wherein the substrate-bonding group is covalently bonded to the substrate and the surface graft polymer chain pattern is formed by regions having the graft polymer chain and regions not having the graft polymer chain.
A conductive pattern formation method comprising:
- exposing a surface graft material including a substrate and a surface graft polymer chain, which includes a polymer chain, a photocleavable moiety and a substrate-bonding group in this order, so as to cleave the photocleavable moiety in exposed areas;
- removing the surface graft polymer chain from the exposed areas to form a surface graft polymer chain pattern formed by regions having the graft polymer chain and regions not having the graft polymer chain;
- and
- providing an electroless plating catalyst or a precursor thereof onto the regions having the graft polymer chain;
- and
- conducting electroless plating to form a metal thin film,
- wherein the substrate-bonding group is covalently bonded to the substrate, and the surface graft polymer chain further has a functional group which can interact with the electroless plating catalyst or the precursor thereof.
