SURFACE CHARACTERIZATION USING HANSEN SOLUBILITY (COHESION) PARAMETERS

Surfaces can be reliably characterized by the cohesion energy parameters, of the type commonly called Hansen Solubility parameters (HSP). Data for many fillers fibers, pigments and other surfaces are available. The implication for composites is that the physical affinity or cohesion between fibers and polymer matrix will be a maximum when the energy parameters match. The HSP parameters assigned to many liquids and polymers have recently been confirmed by statistical thermodynamic treatments
