“…It became possible to produce metallopoly mer composites bearing almost any type of matrices (organic, inorganic) and fillers, including metal pow ders with nanosized particles. In [1][2][3][4], composite materials based on organic matrices (high pressure polyethylene, polytetrafluoroethylene, polypropy lene, and polystyrene) containing metal particles (Fe, Ni, Cr, and Ag) were obtained. At the same time, the polymers in use have low light transmission coeffi cients (α = 0.5-0.6), which complicates their use in optical devices.…”
