Abstract
Disclosed is a method for the preparation of a polymer-metal cluster composite material having usefulness as a non-linear optical material or high-modulus material. The method comprises bringing a polymeric resin into contact with vapor of a heavy metal compound such as an acetylacetonato complex compound of palladium, platinum or copper under a non-oxidizing atmosphere at a temperature higher than the glass transition temperature of the polymeric resin so that the metal compound vapor is dissolved into the polymeric resin in a glassy state and is in situ reduced into the form of an elementary metal forming clusters of the metal particles.
Claims8
A method for the preparation of a polymer-metal cluster composite which comprises the steps of:
