METHOD FOR PRODUCING POLYMER FILM WITH HIGH CONCENTRATION OF SILVER NANOPARTICLES |
摘要 |
A method for producing a polymer film of polyvinyl alcohol (PVA) having a high concentration of silver nanoparticles (NPs) includes forming the NPs by drying the forming composition by the process of slow reduction of Ag ions by soft organic reductants. Changing a filling degree of Ag NPs in the film is achieved by displacement of Ag NPs and their seeds generated in the liquid PVA film under the action of a DC current at 2-6 mA. An example metal-polymer film with Ag NPs may be used in stealth technologies, for creating thermophotoelectric (TPE) elements, photo detectors, radiation cooling and heating of optoelectronic devices, in spectroscopy of surface-enhanced Raman scattering (SERS), and for manufacturing LC devices. |

1. A method for producing a polymer film based on polyvinyl alcohol (PVA) having a high concentration of silver nanoparticles, comprising:
reducing silver nitrate in a viscous forming composition to synthesize the silver nanoparticles; drying the forming composition by reducing silver ions with organic reducing agents to form the silver nanoparticles; applying an electric field to change a filling degree of the silver nanoparticles forming in the polymer film and to stabilize the silver nanoparticles; and applying a UV radiation to accelerate reduction of the silver ions and to dry the polymer film. |
