polypyrrole nanoparticles synthesized in a continuous microfluidic reactor

Polypyrrole (ppy) nanoparticles have been synthesized successfully by oxidation polymerization in droplet microfluidic system. the resulting particles were characterized by fourier-transform infrared spectroscopy, field emission scanning electron microscope, transition electron microscope, x-ray diffraction, thermal gravimetric analysis, and cyclic voltammetry. the in-channel synthesized nanoparticles are compared with those of ppy synthesized via conventional discontinuous batch reactor. the in-channel synthesis method leads to ppy nanoparticles that are different in properties such as improved conductivity over the regularly synthesized ppy. in comparison, the method is a fast, continuous and efficient method for ppy synthesis.
