STUDIES ON ANTISTATIC METHOD FOR POLYMERS .1. CONDUCTIVE BEHAVIORS OF CONDUCTING SUBSTANCE IN SOLID AND LIQUID-PHASES

An investigation was made of the relation of the charging rate constant (Kc) to the concentration, the apparent molecular distance and the system viscosity for a conducting substance (2-ethylhexyl m-aminobenzoate) which was uniformly dispersed into dodecylbenzene (liquid phase) or ethylcellulose (solid phase). The relation of Kc=ACn between Kv and the concentration (C) of a conductive substance is obtained, where n is 7.6 for solid phase and 3.6 for liquid phase. Kc increases remarkably when the molecular distance is about 9.6Å in the solid phase and about 12.0Å in the liquid phase. Kcs in both phases are about 3.3 min-1. Kc decreases having a maximum peak in the range of 200 cp with the increases in the viscosity of the system. The Kc of soda-lime silicate glass, which is known as a material free of electrification troubles, is 5.8 min-1. © 1979, The Chemical Society of Japan. All rights reserved.
