Light Guide Film

Nov 25, 2016

Bartlett and Pillai first discovered PMDA / ODA polyimide light guide phenomenon, which is due to the formation of charge transfer between molecules complex. The less the energy required for the excited state of the charge complex formed by the more regular arrangement of the polyimide molecules. In the direction perpendicular to the molecular chain direction of the light guide type is the strongest, so the polyimide LB film may obtain high light guide type.
