Description
Summary:The present study aims to investigate the electromagnetic wave transmission, reflection, and absorption characteristics of polyaniline (PANI)-coated transparent thin films. To investigate the intrinsic electromagnetic radiation shielding/absorbing characteristics of PANI-coated transparent thin films, the optical transmittance, sheet resistance, and electromagnetic interference (EMI) shielding efficiency (SE) of the films were systematically investigated. In addition, the applicability of an SE formula is checked by comparing the present experimentally measured SE values with calculated SE values. The results show the potential use of PANI-coated transparent thin films as an EMI shielding/absorbing material that satisfies both optical transmission and EMI SE requirements for transparent bodies such as windows or doorways of buildings.
