| Summary: | The electrical properties of coconut-shell activated carbon
have not been thoroughly investigated and are, therefore, not
well understood. In order to study these properties
meaningfully, a fairly satisfactory knowledge of the structure,
microstructure and composition of the material is needed.
Since the material's constitution has been little studied
and dealt with in the relevant published literature,
investigation of the structure and composition of the material
has to be done in a comprehensive manner.The experimental
investigation is divided into two categories. Firstly, the basic
experimental work, which is considered important in order to
provide supportive evidence to any proposed model of
charge-carrier conduction and dielectric behaviour, consists of work on x-ray diffractome try, neutron activation analysis,
Fourier transform infra-red spectroscopy, scanning electron
microscopy, thermoelectric power and magnetoresistance.
Secondly,the main experiments consist of work on direct current
conductivity and alternating current conductivity measurement. |
