“…For adhesion properties determination of modified coatings from the studied composite materials, the method of cathodic exfoliation was used. In this case, the characteristic property of the adhesion interaction is the defect diameter, which is formed in the coating of the composite material on the metal (steel grade St3) . Results, obtained by this method are shown in Table .…”

We investigated the composition and surface energy characteristics-the surface free energy, its acid-base and dispersive components, acid and base parameters (according to the van Oss-Chaudhury-Good method), and acidity parameter (according to the Berger method) of composite materials based on the ethylene-vinyl acetate copolymer with the addition of new aromatic petroleum resins in different percentage ratios. The thermal properties of the compositions were studied by the methods of differential scanning calorimetry and thermal gravimetric analysis. An ambiguous influence of various resin brands on the thermal effects in the compositions was observed. The physical and mechanical properties of the compositions as well as their adhesion to metal substrates were investigated. A significant increase in adhesion, tensile strength, and in relative elongation could be achieved for ethylene-vinyl acetate copolymers due to the modification with new petroleum resins. This article is the second part of a study on surface properties with new brands of new petroleum resins in order to optimize their selection for polymeric composite materials. Here, a comprehensive study on the effect of petroleum polymer resins on various properties of polymer composite materials based on ethylene-vinyl acetate was carried out. POLYM. ENG.

“…The metal surface was previously pretreated by sandpaper and subsequently degreased with acetone, in order to improve the mechanical adhesion. The adhesion of the EVA–metal compound was judged by the defect diameter after cathodic exfoliation for 8 hr at 8 V .…”

“…Although the surface energy cannot be measured directly, different indirect methods have been proposed in the literature 33, 34. In this work, the geometric‐mean34–36 approximations were used to get the dispersive and the nondispersive contributions to the total surface energy of the base, modified, and the unmodified PE composites. These expressions will be used here only to compare the effects produced in the surface fluorination.…”

Composites consisting of high density polyethylene (HDPE) reinforced with randomly oriented chopped Twaron fibers (both fluorinated and nonfluorinated) show a significant increase in mechanical and thermal properties. To increase the better fiber matrix adhesion, the Twaron fiber is surface fluorinated using elemental fluorine. The surface of the Twaron fiber becomes very rough and the diameter of Twaron fiber increases from $ 12 to 14 lm after fluorination. The composites were prepared using solution method to overcome the damage of the fiber. The tensile strength and the Young's modulus increases with increasing fiber content. The tensile strength and modulus of modified fiber (fluorinated Twaron fiber) composites is much higher than nonmodified fiber composites indicating that there is better mechanical interlocking between the modified fiber and the matrix. Thermal properties obtained from DSC and DTA-TG analysis of the fluorinated fiber composites are also improved. Contact angle measurements, as well as the surface energy measurements, indicate that the composites are more wettable and is maximum for fluorinated fiber composites i.e., surface energy for fluorinated fiber composites is highest. Crystallinity is also higher for fluorinated fiber composites.

“…High values of ΔD short relate to strong interactions of the components as well as to more durable joins. The parameter ΔD short was proved and established in recent years for modified and unmodified polyethylene, rubber, and epoxy coatings of various metal substrates . In this paper the shortened Berger method was used for all measurements in order to select the right combination with good adhesion and high resulting mechanical properties of hard–soft pairs.…”

We demonstrate the use of innovative wetting method in prediction of the adhesion properties of biobased polymers for two‐component injection moulding, taking into account the acid–base surface properties of joined materials. The measurements were carried out in accordance with modified Berger method by calculation of the difference in shortened acidity parameter ΔDshort between hard and soft component. Correlation factors up to 0.99 were observed between ΔDshort and peel force. In comparison to results obtained by conventional wetting methods, high potential for the selection of components with high interface adhesion and for prediction of the functionality by the acid–base approach was demonstrated. © 2015 Wiley Periodicals, Inc.
