Abstract
Polymers with advanced properties can be achieved among other measures by reinforcing with fibrous materials, by polymer blending and surface modification. Using the surface treatment of PP‐EPDM injection moulding specimens (washing, flaming, plasma‐treatment) an overview on progress in surface analytics is given. It is shown that XPS, contact angle and zeta‐potential measurements give corresponding results concerning the composition of the surface region.Additional to the kind of interaction forces at interfaces the mechanical properties of reinforced polymers are governed by sorption layers and electrical phenomena at interfaces. Corresponding results were obtained at chalk filled PE‐HD and glass fibre reinforced polyamide.
