Abstract
The electric light scattering effect has been measured in aqueous susp ensions of almost monodisperse, slightly elongated polytetrafluorethyl ene particles, and the influence of particle concentration and ionic s trength investigated. The absence of dependence of the electric light scattering on particle concentration in the range 0.022-1.1% (w/w) at constant ionic strength is considered as evidence that there are no co llective effects in these suspensions. The decrease of the kilohertz ( KHz) effect with increase of ionic strength (from 5 x 10(-5) to 5 x 10 (-3) M NaCl) and displacement of its relaxation frequency towards high er frequencies confirmed the concept for the interfacial origin of the electro-optic effect in dilute suspensions.
