| Description |
Electromagnetic interference is pollution generated due to dense nature of circuitry in electronic devices and is required to be
control at its source. Polyaniline is an environmentally stable conducting polymer which can be cast as thin film, which can replace
the corrosive metals as a shield for the control of electromagnetic radiations. In this communication we discuss our results on the
preparation of flexible freestanding conducting polyaniline film of varied thickness using either p-toluenesulphonic acid (PTSA) or
camphor-10-sulphonic acid as a primary dopant and 4-chloro-3-methyl phenol (CMC) as a secondary dopant. The resulting films
were characterized by conductivity, scanning electron micrograph and shielding effectiveness measurements (SE). The SE measurements
were carried out using co-axial transmission line method in the frequency range of 0.1–1000MHz. We noticed that only the
change of 2% in the shielding effectiveness of these films over the period of 3 years indicating the environmental stability of polyaniline
films.
