Conductive Property

This paper presents a systematic study of the nano-sized structure and temperature dependent electrical properties. A method of synthesizing the self-assembled multi-walled carbon nanotube (MWCNT) nanopaper on hydrophilic polycarbonate membrane was explored. The process is based on the very well-defined dispersion of nanotube and controlled pressure vacuum deposition procedure. The experiment results show that the ratio changes of MWCNT in the nanopaper could lead to the changes in the electrical conductivity efficiency of the nanopaper. Furthermore, the electrical resistivity of MWCNT nanopaper decreased as temperature increase.

Poly(vinylidene fluoride)(PVDF)/Multi-walled carbon nanotube (MWNT) composites were melt blended using internal mixer. The relationships between structures and physical properties of thin PVDF/MWNT composite films were studied. With increasing the content of MWNT, the size of spherulites in PVDF decreased. MWNT was used as a nucleating agent. The incorporation of MWNT produced a polar β-form crystal structure of PVDF. The permittivities of thin PVDF/MWNT composite films were increased with increasing the MWNT content. The percolation level in electrical conductivity occurred between 2 and 2.5 wt%. The critical conductivity saturation point for the electrical conductivity in PVDF was confirmed. Similar tendency was also observed in thermal conductivity.
