Carbon black / phenol resin nanocomposite particles were prepared by mechanical treatment. Bulk bodies were fabricated using these nanocomposite particles by uniaxial pressing and slip casting technique to control the electrical conductivity. Scanning electron microscope (SEM) observation showed dense and thick layer of carbon black were formed on the phenol resin particle by mechanical treatment. electrical conductivity of the bulk body prepared using hollow carbon black was higher than that using dense carbon black. The bulk body fabricated by slip casting technique showed higher electrical conductivity than that by uniaxial pressing because of development of percolation structure due to higher coordination number of nanocomposite particles.
