The stability of plasma polymer matrix with functional metal fraction was investigated by UV/VIS and SEM techniques in this study. Compared are properties of Ag/plasma polymer nanocomposites where magnetron sputtered PTFE and nylon 6,6 serve as plasma polymer matrix.
Silver was immersed into the matrix by two different ways: (i) in the form of nanoislands, formed by diffusive coagulation of deposited Ag atoms onto the plasma polymer, and (ii) by directly deposited Ag particles of size about of 11 nm grown in a gas aggregation cluster source. The Ag nanoislands or Ag nanoparticles were sandwiched in between plasma polymer layers with the top layer thickness that varied in the range 5-20 nm.
Stability of prepared nanocomposites on air, in water and at elevated temperatures is investigated and compared in dependence on the matrix material as well as in dependence on the form of Ag nanoinclusions.
