Abstract:
Natural textile materials are well known as electrical insulators, but a certain level of electrical conductivity is required in many applications such as electromagnetic shielding or electrostatic elimination. Improved electrical conductivity can be obtained by adding metal fillers in textile materials. Addition of copper(I) oxide particles into linen fabric can be achieved by screen printing on a semi-automatic machine S-300. The printing is done with a modified alginate pasta with addition of Pinus sylvestris L. alcohol extract and copper oxide particles. Dielectric parameters such as conductance and susceptance are measured using a HAMEG LCR bridge in the frequency range from 24 Hz to 125 kHz at 24 ± 0.3 °C. The specific conductance and susceptance show an increase with frequency by three orders of magnitude in all measured samples. The measurement results show three times higher specific conductance in samples modified with copper(I) compared to unmodified samples.
