Incorporated oriented polar molecules in PMMA polymeric films: Characterization by Kelvin probe technique and atomic force microscopy

Betaine type dipolar molecules have received considerable attention because of their large dipole moments and optical non-linearities. The host-guest systems are chosen. The high-electric field corona poling was used to generate dipole orientation of betaine molecules in polymer matrices. Atom force microscopy and surface potential studies yield useful information regarding both structural and electronic properties of casted host-guest polymer films. In this work we present results obtained from surface potential and atom force microscopy studies of poled and un-poled thin films on heating.
