The change of resistivity of the epoxy-based nanocomposite was studied in dependence on concentration of dispersed
nanoparticles. The SU8 negative-tone photoresist was applied for the polymer matrix and the conductive carbon black
powder for the fillings. The largest decrease of resistivity was obtained at 2-3 wt% of fillings whereas at loadings higher
that 8 wt% it does not decreases further appreciably. The resistivity of the prepared nanocomposites becomes smaller
after the UV-exposure. The applied nanofillings change the viscosity of the material but the spin-coating application still
remains reliable and was approved to work well for concentrations of at least up to 3 wt%. The addition of nanofillings
up to 2 wt% does not destroy the resolution of photolithography as seen on the standard test pattern with line widths from
2 to 10 μm.
