Electropolymerization of Polypyrrole Thin Film in a Drop Tube

Abstract

A technique for preparation of conductive thin films of polypyrrole in 10 seconds was developed using electrochemical polymerization and metal dithiolene complexes as electrolyte to detect the effect of microgravity environment available in a drop tube. Under microgravity, solute migrates less efficiently due to suppressed convection of solution and the reaction rate is reduced. The polypyrrole thin film prepared under microgravity contains less anion metal complex and is more electrochemically stable than in ground-based polypyrrole.
