Leading national thinking on politics, government & public policy through Open Access research

Strathprints makes available scholarly Open Access content by researchers in the School of Government & Public Policy, based within the Faculty of Humanities & Social Sciences.

Research here is 1st in Scotland for research intensity and spans a wide range of domains. The Department of Politics demonstrates expertise in understanding parties, elections and public opinion, with additional emphases on political economy, institutions and international relations. This international angle is reflected in the European Policies Research Centre (EPRC) which conducts comparative research on public policy. Meanwhile, the Centre for Energy Policy provides independent expertise on energy, working across multidisciplinary groups to shape policy for a low carbon economy.

Abstract

Charging and discharging currents due to the application of a step voltage to styrene butylene rubber (SBR) 50 mum thick were measured for a 1.27 x 10(5) s as a function of temperature from 30 to 120degreesC. Activation energies were derived from the isocronal measurements of the charging currents for two distinct temperature regions. Transformation of the discharging current to the frequency domain identified two loss peaks. An activation energy was determined for the higher frequency peak. Curve fitting allowed the resolution of the lower frequency peak and the determination of the temperature dependence of the fitted parameters
