Abstract
This paper highlights about synthesis and characterization of tubular polyaniline (PANI) which have prominent application in electromagnetic absorbers. PANI has been synthesized using template method under in-situ polymerization process. The morphology of the synthesized PANI was carried out using Scanning Electron Microscopy (SEM) and optical microscopy. Various effective constituent parameters e.g. dielectric constant and loss tangent of PANI were measured using Free Space Measurement System (FSMS). Furthermore a fabricated electromagnetic absorber composite based on the optimized ratios of the PANI and the polyurethane (PU) resin on Teflon coated glass fabric template, possess minimum 20 dB reflection loss (99% absorption) in 8–18 GHz frequency region possesing composite thickness of 2.5 mm.
