Abstract
  • Measurable surface parameters which may be related to the response evoked upon contact with biofluids have been suggested to provide direction for characterization, prediction, and ultimate control of biofluid behavior at interfaces. With respect to fouling of heat exchange equipment by biofluids, such properties may be useful for the development of models which include a surface-related term. However, their dependence on temperature has not been adequately studied. Surface energetic parameters for a variety of contact surfaces were recorded at temperatures from 7 to 80°C using contact angle analysis with a modified sessile drop technique. A linear dependence in surface energetic properties with temperature was observed. The observed temperature effect suggests a need for account of this influence in development of models describing biofluid-contact surface interactions outside of the ambient range.
