Surface and interface properties
Study and analysis of the surfaces of the solid polymers Physicochemical properties

Depending on the properties required, polymer surfaces can be characterized by various complementary methods. For example, you may need to know :

• topography, often described as roughness ranging from the atomic scale (e.g. molecules) to the macroscopic scale (form deviations);

• morphological texture: distribution of crystalline lamellae and amorphous phase, spherulites or other morphologies;

• electronic structure: knowledge of core and valence bands ;

• composition: nature of the elements present, their bonds and concentration;

• optical characteristics, such as transparency and brightness.

• surface mechanical characteristics, such as surface modulus of elasticity, hardness, scratch resistance, adhesion and, more generally, surface rheology
