Journal ArticleDOI
Thin polyaniline films in EMI shielding
TL;DR: In this paper, the authors measured the electrical interference shielding efficiency of polyaniline-Camphor Sulfonic acid (PCA) films in the near-field and far-field with a dual-chamber box and a transmission line method in the frequency range 0.1-1000 MHz.
Journal ArticleDOI

TL;DR: In this paper, the properties of melt and solution processable poly(3-alkylthiophenes), P3AT, and a thermoplastic matrix polymer made using ordinary melt processing techniques were reported.
Journal ArticleDOI
Electrical conductivity of synthetic DOPA-melanin polymer for different hydration states and temperatures
TL;DR: It has been shown, that in the range of relative humidity values (0-100%), changes in the hydration state of melanin have predominant influence on electrical conductivity in comparison to temperature.
Journal ArticleDOI
Electrical and optical properties of FeCl3-doped polyparaphenylene
Journal ArticleDOI
Synthesis and properties of FeCl4-doped polythiophene
TL;DR: In this paper, the maximum conductivity of PT-FeCl 4 -films was observed to be 50 Scm −1 which corresponds to a maximum dopant concentration of approximately 26 mol-%.
