Field emission characteristics of chloride doped polypyrrole (Cl-PPy) films have been investigated. For this purpose, freestanding Cl-PPy films have been synthesized by interfacial polymerization from two different monomer (pyrrole) concentrations (1 and 0.1 M), keeping the monomer to oxidant (FeCl₃) concentration ratio equal to 1. The surface morphology of these Cl-PPy films, as revealed from scanning electron microscopy, was found to be granular in nature. The average grain size of films prepared using 1 and 0.1M pyrrole concentrations were ˜2.5 and ˜1μm, respectively. The measured threshold field, that is, field required to draw an emission current density of 10μA/cm², for these two films were 0.27 and 0.15 V/μm, respectively. From these films, a maximum current density of 1 mA/cm² could be drawn at an electric field of 0.42 and 0.29 V/μm, respectively. The field emission current (investigated at a preset value of 1μA) was found to be very stable up to 3h, suggesting utility of Cl-PPy films as a novel material for field emission based applications.
