Cryochemical synthesis and structure of metal-containing poly(p-xylylenes): System poly(chloro-p-xylylene)-Ag

Polymer films with small Ag-clusters and Ag-nanocrystals were obtained by the cocondensation of Ag and chloro-p-xylylene from the gaseous phase followed by low-temperature solid-state polymerization. UV-Vis spectroscopic data show that the annealing of films at ambient temperature and thereafter at 373 K leads to a sharp rise of the amount of Ag-nanocrystals by aggregation of small clusters, but the mean size (l) over bar of the nanocrystals remains practically constant. According to X-ray data, the lattice of Ag-nanocrystals is close to that of metallic Ag and (l) over bar is equal to approximately 50 Angstrom.
