Polymer nanofluids of polyvinylidene fluoride 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.
