    Poly(lactide) (PLA) synthesized from starch is attracting much attention, since it is biodegradable and is able to attain a good mechanical property by a proper process such as stretching. It is known that the two PLA isomers, PLLA and PDLA, strongly interact with each other. Therefore, if the two isomers are blended, they form racemic crystals (stereocomplex). Since little is known about the effect of forming the stereocomplex on the dielectric properties, permittivity and thermally stimulated polarization current are compared among two kinds of PLLA films and a stereocomplex film. As a result, both the permittivity and current were found to become larger with a decrease in the crystallinity, irrespective of the crystal structure of the sample.
