Summary: Poly(hydroxyurethane-urea)s (PHUUs) with complementary properties to poly(hydroxyurethane)s (PHUs) and polyureas have great potential for practical applications. Novel PHUUs were synthesized through polyaddition reaction using 5-membered dicyclic carbonates and amino terminal polyurea oligomers. The introduction of urea moieties improved surface hydrophobicity and thermal properties, and the structure of selected diamine influenced glass transition temperature and mechanical properties of PHUUs.

Summary: The use of polymer-associated hexafluorides as coatings provides a viable alternative to chromium-VI metal treatments, improving both adhesion and corrosion resistance. This study investigated the relationship between surface energy, paint adhesion, and corrosion resistance of painted aluminium panels. The results showed that higher aluminium surface energies correlated with improved paint adhesion, while limited corrosion was related to lower polar surface energies. The addition of polymers to hexafluoride treatments increased polar surface energy and enhanced corrosion resistance and paint adhesion. These findings can contribute to the development of new polymer chemistries in conversion technologies.

Summary: Robust fluorine-free superhydrophobic films were successfully prepared using a mixture of fatty acids, SiO2 nanoparticles, and polydimethylsiloxane. The films exhibited a highly textured morphology, with a water contact angle of 162 +/- 2 degrees and a sliding angle of <5 degrees. The superhydrophobicity of the films remained intact even after exposure to UV light, heat treatment, multiple tape peeling cycles, and various organic solvents.

Summary: The adhesion between aggregate and binder can be measured by the surface free energy (SFE), which varies with the changing surface characteristics. This study investigated the effect of surface texture on the aggregate's SFE and established a model to describe the relationship between surface texture index and SFE.

Summary: Polyurethane adhesives and coatings are widely used due to their excellent properties, but a major drawback lies in the use of toxic isocyanate-based starting materials. Non-isocyanate polyurethanes have emerged as greener alternatives, but industrial implementation is still at an early stage.

Summary: This study reports on the stable and impalement-resistant superamphiphobic coatings enabled by phase-separated adhesive, which are capable of resisting adhesion from viscous liquids with low surface tension. The coatings exhibit a hierarchical micro-/nanostructure and numerous perfluorodecyl groups on the surface, resulting in excellent static and dynamic superamphiphobicity, as well as mechanical and chemical stability.

Summary: This paper aims to enhance the metal-hydrophilicity and high-temperature wear resistance of copper wheels for the preparation of amorphous ribbons. Different microstructures of nickel layers were prepared on polished copper plates through electrodeposition and chemical etching. The study reveals the specific factors influencing wettability variation in working and idle states by investigating surface characteristics, phase composition, liquid contact angle, and surface free energy of the coatings. The research findings provide a reference for improving the long-term metal-hydrophilicity and wear resistance of solidified substrates.

Summary: This study demonstrates that accurate refinement of atmospheric plasma technique can achieve polymeric coating near the super-hydrophobic regime, and proposes a reliable workflow for surface characterization and smart design. By quantitatively distinguishing the contribution of a PFDA coating, the role of surface chemistry and roughness in reducing surface free energy is decoupled, highlighting the synergistic combination of models and experiments in designing low-free-energy surfaces.

Summary: The contact angles of water and various organic liquids on native and acetylated cellulose were calculated using molecular dynamics simulations. The wetting behavior was found to be influenced by the liquid surface tension. Acetylation decreased the work of adhesion to most liquids, including nonpolar ones, while others were unaffected. Water showed the highest affinity to both native and acetylated cellulose. These findings have implications for liquid infiltration of nanocellulose networks and the interaction between cellulose and different liquids.

Summary: Fast removal of water drops from solid surfaces is important in many applications. The reduction in lateral adhesion of water drops on PDMS brush surfaces after exposure to various organic vapors was reported and attributed to the physisorption of vapor and swelling of the PDMS brushes. Contact angles of water drops on three hydrophobic surfaces in different vapors are measured to determine the contribution of vapor adsorption and change in interfacial tensions on drop adhesion. The findings show that vapor-induced change in interfacial tensions can explain the decrease in contact angles, while vapor adsorption into PDMS surfaces forms a lubricating layer, reducing contact angle hysteresis.

Summary: The wetting characteristics of epoxy and phenolic resins on metals are influenced by the molecular interactions between the functional groups of the resins and the metal surface. Theoretical adhesion energies can reveal the microscopic adhesion mechanisms of epoxy-phenolic coatings on metals. Experimental results show that epoxy resins have superior adhesion compared to phenolic resins, with epoxy resins containing a higher content of epoxide-to-hydroxyl groups showing improved adhesion. Additionally, the adhesion of coatings on tin-free steel is found to be higher than on tinplated steel due to increased formation of hydrogen bonds.

Summary: Ti3C2Tx MXene stands out from other 2D nanomaterials with its hydrophilicity, and the static contact angle value is independent of the background substrate wettability. In addition, a significant contact angle hysteresis is observed on a smooth surface, which is likely due to the chemical heterogeneity of surface terminal groups.

Summary: The study aimed to determine the polar and dispersive surface free-energy components of the central layer of corrugated paperboards made of recycled fibers. The polar and dispersive components, as well as the total surface free energy, were calculated using contact angles of water and diiodomethane liquids on recycled cellulose sheets. The total surface free energy of the middle layers of two different grammages ranged from 47.9 mN/m to 51.05 mN/m. The polar contribution to the total surface free energy of the two types of sheets ranged from 8.6 mN/m to 12.6 mN/m, which was significantly lower than that of water. The contact angle method proved to be a reliable way to estimate the surface properties of industrially made recycled paper products.
