摘要：

Thin poly(p-xylylene) films containing lead nanoparticles were prepared by vacuum deposition technique. The vapors of p-xylylene monomer and lead were condensed onto the surfaces cooled down to 80 K. Films thus obtained were characterized by electric conductivity measurements during film samples formation. Such metallopolymer films exhibit sensor activity in the presence of ammonia in the atmospheric air. The influence of air humidity and the co-operative effect of ammonia together with water vapors on film resistance were studied. (C) 2002 Elsevier Science B.V. All rights reserved.
