Effect of solvent vapour annealing on polymer thin films and application in nonlinear optical fields†
Abstract
Solvent vapour annealed (SVA) technique was successfully used in controlling the morphology of polymer thin film blending with low molecular weight chromophoric (LMWC) molecules. The films investigated by XRD, UV-vis, AFM and TEM. Outstanding electro-optical signal was detected on the films prepared by SVA method, confirming their applications in nonlinear optical fields.
