Photochemical formation of electrically conductive silver nanowires on polymer scaffolds

“…It was reported that PVA could not act as a reducing agent without any irradiation but worked as a good reducing agent under photoirradiation by generating radical species [43]. Mills' group reported earlier on the formation of metallic particles during photoirradiation in the presence of PVA [44]. Using our method, we believe that radical species or solvated electrons formed during the photoirradiation of PVA are responsible for the reduction of Ag + to Ag(0).…”

Chitosan/silver nanocomposites: Synergistic antibacterial action of silver nanoparticles and silver ions

“…Absorptions peaks centered between 270 and 300 nm are in place of those related to nanoparticles and can be assigned to different clusters of silver ions such as Ag + , Ag +2 , Ag +3 [33][34][35]. This means that the majority of Ag + ions chemically interact with the dilute acetic acid and form CS/silver acetate as a source of silver ions [27].…”

Nanocomposites Based on Thermoplastic Polymers and Functional Nanofiller for Sensor Applications

“…The preparation of silver “nano-dispersion” directly in the PVA matrix by a one-step method based on the reduction of the inorganic precursor through a solid state synthesis has been achieved by thermal annealing [130] and UV irradiation [131,132,133], which result very efficient methodologies because they take advantage on the formation of a complex between the PVA matrix and the silver nitrate: Ag + ions can be easily chelated by the hydroxyl groups of the polymer and then reduced directly in the host matrix.…”
