Abstract
In this research, the effect of electric polarization on the kinematics and distribution of grain growth and grain size respectively in organic thin film of poly (2-methoxy-5-(2-ethylhexyloxy)-1, 4-phynylenevinylene) MEH-PPV conducting polymer have been studied. An atomic force microscope was used to measure the grain size of the MEH-PPV thin films. We developed surface morphological data and analyzed. The data shows major asymmetric grain growth (from spherical grains at room temperature to lingered needle like-shapes after polarization) under an application of electric field during cooling of polymer film. The grains show evidence of highly ordered, domain-oriented arrangement of MEH-PPV grains after polarization.
