“…In order to realize minimum damage and ensure enough bond strength, it was of great importance to reduce the heat effect during the laser ablation. Some researches 37,38 found that the UV laser treatment PEEK surface generated smaller heat effect than IR laser but the cost is relatively high. In addition, laser treatment with nano-second pulse width was a cut-down contact time with sample surface, which led to a chemical change in the surface components and reduce the surface damage of the bonded substrate.…”

In this study, laser surface treatment was applied to alter the surface texturing and chemical compositions of fused deposition modeling (FDM)-printed PEEK/CF samples to improve the deficiency of inert surface of PEEK as adherend substrate. The influence of IR-laser parameters including treatment gaps, single pulse energy and pulse widths on surface properties and shear bond strength were discussed. The results indicated that surface roughness was enhanced with decreasing treatment gap or increasing pulse energy, which reached the highest value of Ra = 32.44 μm at 0.4*0.4 mm 2 treatment gap and 300 mJ single pulse energy. By adjusting laser pulse width, surface wettability changed from hydrophobicity to hydrophilicity. After micro-second laser ablation, the texturing structure was changed and acted as mechanical interlocking effect, and therefore make the shear bond strengths improve from 3.28 to 6.42 MPa compared with the untreated groups. On the other hand, functional groups on substrate surface were activated after nano-second laser ablation, which contributes to an enhancement of shear bond strength through chemical interaction between adhesives and substrates. Therefore, our work highlights an efficient method of laser surface treatment on the adhesion property of FDM-printed substrates.

“…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.

“…Für das Formamid, Glycerin, Anilin sowie 88 %ige Phenollösung wurde der Kontaktwinkel erst nach dem Erreichen der thermodynamischen Stabilität (nach 2 Minuten) ermittelt. Diese Vorgehensweise wurde in 15 vorgeschlagen. Alle Messungen wurden im Normklima bei 23 °C und einer relativen Luftfeuchtigkeit von 50 % durchgeführt.…”

Moderne Verfahren zur Bestimmung der freien Oberflächenenergie sowie deren Parameter wurden an diversen Kunststoffen sowie Klebstoffen analysiert. Dabei wurden für feste Polymeroberflächen als am besten geeigneten Methoden zur Bestimmung der Benetzung die Verfahren von Berger sowie van Oss-Chaudhury-Good ermittelt. Bewertet und modifiziert wurden außerdem Methoden der nichtlinearen Systeme von Della Volpe und Siboni. Durch eine Anwendung von räumlichen Gleichungslösungen wurden diverse Daten zur freien Oberflächenenergie sowie ihrer Komponenten für eine Reihe von Polymeroberflächen bestimmt.Modern methods for determining the surface free energy and their parameters were analyzed in the context of the presented investigations. The method of Berger and van Oss-Chaudhury-Good were found as the most suitable method for the determination of wetting solid polymer surfaces. Methods of nonlinear systems by Della Volpe and Siboni were evaluated and adapted. Various data of the surface free energy as well as its components have been identified for a number of polymer surfaces by application of spatial equation solutions.
