WebFigure 4. Dispersive, specific and total surface energies for carbon fibres and polymers. The surface energy of the individual components can now be used to estimate the interaction between each polymer-fibre pair. Such an estimation is obtained from the calculation of the work of adhesion, WA by applying Eq.1. WA total = 2(1 d d* 2) 1/2 + 2(1 sp * Corona treatment is a surface modification method using a low temperature corona discharge to increase the surface energy of a material, often polymers and natural fibers. Most commonly, a thin polymer sheet is rolled through an array of high-voltage electrodes, using the plasma created to functionalize the surface. The limited penetration depth of such treatment provides vastly impro…
