Degradation Studies Of Polypyrrole Coated Fibers For Microwave And Millimeterwave Obscurants

Abstract

ABSTRACTMicrowave and millimeterwave obscurants based on typical millimeterwave materials do not environmentally degrade with respect to their physical and electrical properties. The use of conductive polymer coated films and fibers with inherent environmental instabilities are being investigated as possible alternatives. Achieving the optimum electrical performance is highly dependent upon the polymer/dopant combination, deposition conditions, morphology, and volume of the coating that is used. Several conductive polymer coated fiber systems were investigated via thermal analysis. The effects of processing conditions on performance and stability were studied.
