Investigating properties of a manufactured polymer film, a coated item or the behaviour of a polymer melt requires a qualitative and quantitative appreciation of the interaction at all surfaces.  The polymer / air, polymer / substrate interactions are crucial.

Contact angle measurements are important as is the understanding of surface chemical analytical techniques such as XPS and SIMS. Plasticisers and mobile low molecular species can affect wetting characteristics too which can be determined by FTIR leaching tests.
