“…The adhesive interaction between an additive (e.g., NPR) and the matrix material increases thereby with the presence of suitable chemical groups on the surface and by increasing the absolute difference in acid–base properties . This has been already practically demonstrated .…”

“…Since PRs appear as components of polymeric compositions, in nearly all cases it is important to know their surface characteristics, and particularly, their acid–base properties. These properties largely determine the nature of interactions at polymer‐additive interfaces, and the effectiveness of these interactions determines the performance of the final product . Knowledge of resin surface energy properties allows the prediction of the compatibility with the polymer matrix, as well as potentially possible interactions with other ingredients in the composition.…”

We investigated the composition and surface energy properties-the surface free energy, 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) for several types of aromatic petroleum resins (PR). We could see that the Berger, nonlinear systems, and spatial methods provide slightly different information about the acid-base properties of PRs. For acid-base properties, relevant proton content was determined for each sample by nuclear magnetic resonance spectroscopy. Correlations between the composition and surface characteristics of the studied aromatic PR have been revealed. According to the data obtained from the acid-base approach and nuclear magnetic resonance spectroscopy, we can predict the possible combinations of PR-polymer with the best interface interaction, which can lead to high mechanical properties.

The existing wetting methods for the determination of acid-base properties on solid surfaces are discussed. Striving for a better understanding of the adhesive polymer interactions in adhesively joined polymers, the methods of Berger and van Oss-ChaudhuryGood were found as the most suitable methods for the investigation of wetting on solid polymer surfaces. Methods of nonlinear systems by Della Volpe and Siboni were adapted and evaluated on plastic surfaces. In the context of these investigations 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.

“…The reported values of contact angle for water on POM using the sessile drop method are 73.5 [34], 75.9° [32], 77±2º [30], 78±2º [31] and 84.9 [33]. On the other hand, the values of contact angle for methylene iodide using the sessile drop ranged between 37.5° [35] and 55.5° [34]. These are showing that there is not a unique value of contact angle but a range of values, the contacts angles obtained here are in between the reported ones.…”

Here, we present the construction and calibration of a low-cost goniometer to measure contact angles by the sessile drop method. Besides, we propose a simple and fast method to calculate the uncertainty in the determination of the surface free energy (SFE) and its polar and dispersive components through the Owens-Wendt model and tested it by using two testing liquids. The goniometer performance and the SFE uncertainty were determined on two polymers: polytetrafluorethylene (PTFE) and polyoxymethylene (POM), by using water and methylene iodide. The values of contact angle measured were used to calculate the SFE and its components with their errors. The SFE values obtained for PTFE were 17.57-17.91 mJ/m 2 , with a relative error lower than 5.5 %, whereas those for POM were 42.80-43.23 mJ/m 2 , with a relative error lower than 4.3%. Both the SFE values and the errors were in the range of those previously reported. Based on the mathematical analysis of the uncertainty propagation in the determination of SFE, we concluded that the uncertainty is minimized when the testing liquids are an apolar liquid and water.
