Stereocomplex (SC) crystals of polylactide were formed in carbon black-filled Poly(l-lactide) (PLLA)/Poly(d-lactide) (PDLA) composite with 10 and 20 wt% of PDLA during melt blending at the temperature between the melting points of homocrystal and SC crystal. From the analysis of Morisita’s index (Iδ) determined from scanning electron microscopy images and through direct current measurements and alternating current impedance measurements, it was revealed that the increase in the number of SC crystals formed during melt blending improves the filler distribution to achieve a uniform pattern.
