Polymer Surfaces in Dry Condition

POLYMER SURFACES IN DRY CONDITION 3.1. Without Incorporation of Tagging Atoms 

When a polymer is kept dry, all polar groups contained in the polymer molecule tend to move away from the interface consequently, the interface is populated with relatively hydrophobic moieties of the polymer molecule. The surface state of a 

Surface Modification is Appiied to Make the Surface Hydrophiiic 

The introduced hydrophilic moieties tend to migrate into the deeper section of the surface state while the surface is kept dry. Such a migration occurs in the direction to minimize the interfacial tension of polymer/air interface. This process has been recognized as the decay of the surface modification effect.
