Abstract
A method to enhance the electronic conductivity of polyaniline grafted E‐glass fabric is described. The influence of substituted aromatic sulfonic acids as primary dopants on conductivity of the grafted polyaniline–E‐glass fabrics is studied. The conducting fabrics obtained in this method were characterized by UV‐vis spectroscopy, scanning electron microscopy, X‐ray diffraction study, thermogravimetric analysis, and conductivity. Shielding effectiveness measurements on these Pan–E‐glass fabrics showed that the performance is improved (i.e., 0.01 MHz = 49 dB, 1000 MHz = 7 dB) compared to earlier studies (i.e., 0.05 MHz = 37 dB, 1000 MHz = 1 dB) without pretreatment of fabrics. Possible application of these fabrics, e.g., for dissipation of electrostatic charge, is suggested. © 2005 Wiley Periodicals, Inc. J Appl Polym Sci 96: 2316–2323, 2005
