Influence of humidity on dielectric properties of nanocrystalline cellulose – triglycine sulfate composites

ABSTRACT Influence of the humidity on dielectric properties of composites nanocrystalline cellulose – triglycine sulfate in weak measuring field (1 V·cm−1) was investigated from room temperature to +120°C in the frequency range from 10−3 to 103 Hz. A comparative analysis of experimental results before and after heat treatment of samples was made. It was shown that before the heat treatment an additional peak at about +20°C in the temperature dependence of dielectric constant and a low-frequency maximum at 1.6 mHz in the frequency dependence of dielectric loss are observed. They are conditioned by the evaporation of water from the sample surface at the beginning of heating and the near–electrode polarization due to the accumulation of charge carriers at the electrode–composite layer respectively.
