Abstract
A method of making a photocatalytic material comprising a base substance and photocatalytic particles bonded on the base substance by chemical bonding through a silane compound. The chemical bonding is bonding a reactive group of the silane compound through graft polymerization to a radical produced on a resin surface of the base substance by irradiating radiation ray. The resulting photocatalytic material has the advantage that, even when used over a long time, the photocatalytic particles are less apt to shed and the resin base is less apt to deteriorate.
