Thermal and dielectric investigations on the blends of κ-carrageenan and nano-structured polyaniline

- The relations between conductivity and the nanostructures of PANIs have been found.
- The aspect ratio and surface roughness of PANIs affect the conductivity of the blends.
- The dielectric relaxation spectroscopy indicates the structural change in details.
- There occurs chain bundle dismissing and moisture desorption with heating.
