In this paper, a micropipette-in-microcapillary method and its experimental setup are described for the study of temperature effects on surface tension. Temperature control within the confined space of a capillary was achieved by coating the outer surface of the housing microcapillary with an electrically conductive, transparent, tin-doped indium oxide (ITO) thin film as a heating jacket. The precision of this technique was discussed according to the comparisons of our results with published reference data for water, n-hexadecane, and n-decane at room temperature. The technique was further used to measure the temperature-dependent surface tension of n-decane between 25 degrees C and 110 degrees C and n-hexadecane from 25 degrees C to 200 degrees C. The results were in excellent agreement with available published values, and also indicated linear decrease rates of surface tension with decreasing temperatures. (C) 2012 Published by Elsevier Inc.
