The synthesis and characterization of helical polyaniline in the liquid crystal

The helical polyaniline (PANI) was synthesized through introducing the chiral chemical D-camphor-10-sulfonic acid (D-CSA) into the liquid crystal, which resulted in the typical conical texture of lamellar phase pattern, owing to the reorientation and rearrangement of liquid crystal. The morphology a...

Summary:The helical polyaniline (PANI) was synthesized through introducing the chiral chemical D-camphor-10-sulfonic acid (D-CSA) into the liquid crystal, which resulted in the typical conical texture of lamellar phase pattern, owing to the reorientation and rearrangement of liquid crystal. The morphology and the structures of helical PANI were characterized through TEM, Uv-vis, FTIR and XRD, and the influence of the factors such as the amount of D-CSA, stirring, the strength of the electric field on PANI was investigated. Besides, according to the electrochemical data of helical PANI, it was obtained the capacitance of helical PANI synthesized in the presence of electric field was higher, compared with other samples.
