Abstract:
An orchid-like polyaniline (PANI) structures was synthesized by initialing the polymerization at 80°C and growing at 25°C using ethanol and water as co-solvent in the presence of toluene-p-sulfonic acid (p-TSA) as the dopant. The “flowers” are consisted of 8–14 pieces of “petals” with 5–8μm in length. By adjusting the molar ratio of p-TSA/aniline, the cooling rate and the component of the solvent, flake-like and peony-like morphology can also be obtained. The formation mechanism of the orchid-like structure is proposed.
