Photon correlation spectroscopic analysis of a natural electret material: Carnauba wax

摘要

For the first time, photon correlation spectroscopy is applied to the study of an electret material. We show that the average selfhyphen;diffusion parameter of Carnauba wax in liquid phase, from 85 to 170thinsp;deg;C can be written asD=D0+Athinsp;explsqb;minus;Dgr;E/k(Tminus;T0)rsqb;, whereD0=1.6times;10minus;10andA=20times;10minus;10cm2/sec, Dgr;E=82 cmminus;1andT0=68thinsp;deg;C
