Notes:
We have developed a new method to fabricate poly(diphenylsilylenemethylene)(PDPhSM) matrix nanocomposite thin films containing copper nanoparticles produced by laserablation in this paper. First of all, 1,1,3,3-tetra- phenyl-1,3-disilacyclobutane (TPDC) films weredeposited on 4 cm2 silicon substrates cut from c-Si wafers by conventional vacuum evaporation undera pressure of 3.0×10-5 Torr; then copper nanoparticles were deposited onto the TPDC films by laserablation; finally the TPDC films with copper nanoparticles were heated in an electric furnace in an airatmosphere at 553 K for 10 min to induce ring-opening polymerization of TPDC. The resultsindicated that it is possible to fabricate PDPhSM matrix nanocomposite thin films using coppernanoparticles produced by laser ablation. The morphology and size distribution of coppernanoparticles can be controlled by laser ablation conditions. Also, the polymerization efficiencydepends on the size and chemical state of copper nanoparticles
