Abstract
Composites based on biochar derived from sewage sludge as filler in epoxy resin are fabricated and measured in a waveguide in C-band. Biochar is cheap, readily available and environmentally friendly and thus is a very good contender among other carbon-based materials for use in shielding applications. Biochar provide promising results in term of transmission of less than -10dB for a composite with 20wt.% biochar filler. The dissipation loss, calculated from the scattering parameters show that a significant portion of the losses are due to dissipation.
