Polymer nanofluids of poly

PVF2 containing 0–5 wt % Ag nanoparticles
Ag NPs are synthesized via a simple in situ caloric Ag+→Ag reaction in liquid N,N-dimethyl formamide by sonication in hot conditions. An upright dielectric field on formation of a percolation network over the electron donor Ag NPs and electron acceptor CF2 from an ordered
-PVF2 tailors light absorption 250–550 nm and green emission 520–620 nm of variable intensities, with a small percolation threshold of 0.1 wt %Ag NPs. On higher Ag contents, the intensity drops rapidly in both the absorption and emission roughly by an order of magnitude, following the percolation theory of a hybrid dielectric composite. Results open scope of developing newer materials for optical sensors, barcodes, energy transfer pairs, or light emitters.
