AC/DC electrical characteristics of epoxy-multi wall carbon nanotube nanocomposites

Njuguna, Michael, Yan, Cheng, Bell, John M., & Yarlagadda, Prasad K. (2009) AC/DC electrical characteristics of epoxy-multi wall carbon nanotube nanocomposites. In Proceedings of the 6th International Conference on Precision, Meso, Micro and Nano Engineering, Coimbatore, India.


Expoxy nanocomposites with multiwell carbon nanotubes (mwcnts) filler up to 0.3%wt were prepared by sheer mixing and good dispersion of the MWCNTS in the epoxy was successfully achieved. The electrical behaviour was characterized by measurements of the alternating current (ac) and direct current (dc) conductives at room temperature. Typical percolation behaviour was observed at a low percolation threshold of 0.055%. Frequency independent ac conductivity was observed at low frequencies but not at high frequencies. An equivalent circuit models was used to predict the impedence response in these nanocomposites.

Impact and interest:

Citation counts are sourced monthly from Scopus and Web of Science® citation databases.

These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.

Citations counts from the Google Scholar™ indexing service can be viewed at the linked Google Scholar™ search.
