Abstract: In this paper, a modified nonradiative energy transfer method (M-NRET) was used for the study on miscibility of polymer blend.Differing from the conventional NRET, it takes the advantage of labeling one polymer component with both fluorescence donor and acceptor instead of labeling all the components of the blend.This method has been found to be more sensitive to the degree of chain interpenetration in the miscible blends at the molecular level and especially, to be effective to monitor the miscibility-complexation transition of the blends.
