Abstract

Ultrasonic absorption results have been obtained in the range 3 to 29 MHz for dilute suspensions of polystyrene latex, Latices of two types were investigated, following various pretreatments, one type bearing sulphate end groups, and the other bearing both sulphate and sulphonate end groups. It was concluded that when particles are cleaned, the absorption exceeded by far that predicted by theories of viscous drag and heat conduction losses. The excess absorption was clearly attributable to the particle-electrolyte interface. This is emphasized by the sensitivity of the absorption to the counterions, the type of functional surface end groups, and adsorbed polymer. Mechanisms for the excess adsorption are discussed.
