Multidimensional polyaniline structures from micellar templates
Source abstract
Abstract
Polyaniline (PANI) multidimensional (MD) structures (i.e., flowers, sheets, and plates) are successfully synthesized by adjusting the dosage of cationic surfactant cetyltrimethylammonium chloride (CTAC) in the range of 0.050–0.50 g in static HCl solution (0.010 M) at room temperature without stirring. CTAC micellar templates consisting of quaternary ammonium cations and binary persulfate anions direct the fabrication of PANI MD structures. On the basis of the employment of CTAC, the effect of pH value on PANI morphologies is investigated in detail, and followed by the obtainment of other PANI structures, including nanobelts, net-like structures, and particulates. Among the PANI MD structures, PANI sheets in micron size have good dispersibility and excellent processability, which are due to the synergistic effect of PANI’s suitable size and appropriate CTAC molecules. The results and strategies presented here provide opportunities to obtain good water dispersibility to conduct polymer structures with big size.
