Surface functional member (member provided with surface layer of adsorbed functional particles)

摘要

The surface functional member of the present invention has a layer of adsorbed particles which is formed by adsorbing functional particles that are bondable with ionic polar groups onto the substrate on which graft polymer chains having the ionic polar groups are present. The graft polymer chains are preferably formed from a polymerization initiator fixed on the substrate surface by atom transfer radical polymerization. The surface functional member is provided with a layer of functional particles excelling in durability that are firmly adsorbed in the form of a single- or multi-layer structure on its surface so that the functions of the adsorbed functional particles can be exhibited for a long period of time.
