Abstract
Disclosed are a composite material comprising a substrate having a three-dimensional structure which has, on substantially entire surface thereof, regions where a polymerizable unsaturated compound is graft-bonded and regions where the polymerizable unsaturated compound is not graft-bonded, a method for graft polymerization comprising the steps of reacting the surface of the substrate having a three-dimensional structure with droplets of a solution containing a graft polymerization initiator in a suspension or an emulsion comprising the solution containing a graft polymerization initiator and a solvent immiscible with the solution containing the graft polymerization initiator so as to form polymerization initiating regions on the surface of the substrate and thereafter graft-polymerizing a polymerizable unsaturated compound to the surface part where the polymerization initiating regions are formed, and a composite material comprising a substrate which has, on substantially entire surface thereof, regions where a polymerizable unsaturated compound is graft-bonded and regions where the polymerizable unsaturated compound is not graft-bonded.
