Method & Evidence

AimHow do surface treatments influence the interfacial phenomena governing adhesion and adhesive bonding strength in polymer and metal composites?

MethodExperimental investigation using advanced microscopy techniques.

ProcedureElectron microscopy (EFTEM, SEM, STEM) was employed to visualize polymer-polymer interfaces formed by interdiffusion and analyze fractographic evidence of entanglements. Surface treatments on polymers were evaluated for their impact on surface roughness and chemical functionality. Chemical interactions between polymers and metals at fracture surfaces were analyzed, and bonding mechanisms for direct metal-plastic bonding were investigated. Toughness and durability of metal-CFRP adhesive joints were assessed.
