TopicDynamic surface tension in polymer melts.
AnnotationTime dependence of surface tension measured by pendant drop method is given by three factors: by establishing the state when measured data correspond to real ones, then by dynamic surface tension evolution given by physical processes, and finally by chemical changes. Static surface tension values are commonly used, while their measured values are often in fact dynamic surface tension of the surface of certain age. Several equations based on different controlling processes were published for dynamic surface tension in time. A student should, after learning the problem, take part in determination, which of published models describe best the dynamic surface tension in individual materials under different condition, and in determination of parameters of related equations. Knowledge of physical chemistry is expected. Since modification of measuring software will be necessary, ability to work with C programming language is required. Then, knowledge or willingness to learn to work with data fitting to complicated nonlinear equations. "
