Abstract

1D-structural polyaniline (PANI) was controllably synthesized by utilizing the poly(l-lactide) (PLLA) and poly(d-lactide) (PDLA) as controllers. FESEM images showed that the morphology of 1D-structural PANI controlled by PDLA likes a joint obviously unlike PLLA controlled vertebra structure reported previously. To set the ratio of ANI/PLLA (ml/g) at 0.45/0.135, 0.45/0.270 and 0.45/0.540, the formed PANI 1D structure was changed in the cross-section as four round leaves, four non-round leaves and four sharp leaves, respectively. FTIR and XRD analysis indicated that the PLLA and PDLA both were doped in PANI chains while the PLLA was strongly in the electrons delocalization than that of the PDLA due probably to the L-type stronger in crystal polymorphism than that of the D-type.
