Abstract
The effects of CW laser radiation with a wavelength of λ = 532 nm on ethyl methacrylate copolymer films doped with the Ag(hfac)COD silver precursor were studied. Laser heating of the polymer composite (up to 150-170 °C), induced by the formation of highly absorbing silver nanoparticles (NPs), brings about an accelerated photo-thermochemical decomposition of the precursor, plastification of the polymer, local transition of the composite matrix to a colloidal state and intense thermocapillary convection in the dynamic active colloid formed. As a result, a directed transport of silver NPs from the center of the laser beam to its periphery takes place, leading to the formation of a ring structure with a very high concentration of silver NPs.
