Anodic Surface Treatment on Carbon Fibers: Determination of Acid-Base Interaction Parameter between Two Unidentical Solid Surfaces in a Composite System.

An interpretation based on more precise linear free energy relationships is proposed for the determination of the acid-base interaction of a solid surface, in the context of inverse gas chromatography at infinite dilution. This work leads to the evaluation of acid-base interaction parameter, Ia-b, between two constitutive elements in a composite system. In this work, the acid-base interaction parameters between fibers and matrix are greatly correlated with the results of the interfacial shear strength carried out on single fibers and the interlaminar shear strength of the composites. As an experimental result, electrochemical treatment of fiber surfaces significantly appears essential to the improvement of the acid-base character in a way expected from the nature of the electrolytes used during the treatment.
