The use of conductive polymers to produce environmentally friendly multispectral screening materials
Abstract
Fibrous material is being developed that has a conductive polymer coating to achieve effective millimeter wave (MMW) screening performance in an aerosol cloud, and then degrade to a conductively inactive form after settling out. Designing degradability into the material addresses the problem of environmental persistence that is present in the current MMW screening fiber. Synthesis and processing of the candidate fibers is guided by an obscuration modeling program which identifies predicted electromagnetic characteristics as calculated from the interplay of material properties and fiber dimensions. Experimental results are presented comparing the conductivity and the coating quality for doped polypyrrole that is polymerized onto various fiber substrates by a solution process using various solvents and a nonsolution vapor phase process. A new, self-automated, vapor process was developed that produced coated fibers that exhibit higher conductivity values when compared to coated fibers produced by other methods. Single fiber conductivity measurements for the coated fibers are used to assess the quality and the potential screening performance of the conductive polymer coating. Studies have also been conducted on the degradability of the doped polypyrrole coating under outdoor sunlight and humidity conditions. In addition, attenuation studies using a 3 5 GHz transmissometer have been conducted to measure the dissemination and obscuration of the coated fibers.
