Abstract

Fabrication of transparent, conductive phase-segregated ITO/PC composites was accomplished by compression molding of dry mixed constituents. Mixtures of 50nm indium tin oxide particles in a polycarbonate matrix of compositions ranging from phr = 1.0 to 0.001 were measured by optical and electrical methods. Measured transmittance ranged from 5% to 68% at 400nm, 15% to 80% at 700nm, and averaged 10% to 75% across the visible spectrum. Resistance was measured by impedance spectroscopy. Resistivities of the different composites spanned 10 orders of magnitude. Electrical percolation was found to occur near phr = 0.15.
