Summary: We investigated the properties of polyoxyethylene diamine (H2N-PEG-NH2) and poly(amide-imide)-polyethylene glycol (PAI-PEG) copolymers and found that the material had the best elongation at break and recovery when the PEG content was 5%. The degradation rate, hydrophilic property, tensile strength, and tensile modulus of the copolymer decreased with increasing PEG content. The material showed the best thermal stability and mechanical properties when 5% PEG was added. Cytocompatibility evaluation demonstrated that the addition of PEG enhanced the cell compatibility of the material, making it potentially suitable for bone repair applications.

Summary: Icephobic coatings offer protection for infrastructures in cold environments. Aqueous self-lubricating coatings, fabricated by blending PEG-PDMS into a PDMS matrix, enhance contact area, forming hydrogen bonds and quasi-liquid-like layers to reduce ice adhesion strength and delay freezing. Optimized copolymer content of 5% produces durable icephobic coatings.

Summary: The triboelectric effect arises from charge transfer between surfaces under contact, with recent engineering focus on increasing porosity, surface roughness, and use of heterogeneous materials, particularly towards soft and flexible polymer devices. The progress in TE generators is critically evaluated, linking engineered performance to fundamental driving forces of triboelectricity using exemplar triboelectric polymer poly(dimethylsiloxane).

Summary: This study investigates the molecular structure and its significant impact on droplet friction and liquid repellency between liquid-like polydimethylsiloxane (PDMS) brushes and solid surfaces. By replacing the silanol groups on polymer chains with methyls through a vapor phase reaction, the relaxation time of the contact line is decreased from seconds to milliseconds. This results in a substantial reduction in static and kinetic friction of both high- and low-surface tension fluids. The capped PDMS brushes with ultra-fast contact line dynamics demonstrate complete suppression of the coffee ring effect, excellent anti-fouling behavior, directional droplet transport, increased water harvesting performance, and transparency retention following the evaporation of non-Newtonian fluids.

Summary: Colorless polyimide films have great potential for flexible display applications due to their excellent optical transparency and thermal and mechanical properties. By adjusting the molar ratios of monomers, the thermal, mechanical, and optical properties of the copolymers were optimized. The incorporation of amide linkages significantly improved the mechanical properties and dimensional stability of the films. The adoption of CBDA suppressed the formation of charge transfer complexes, resulting in well-balanced optical properties.

Summary: This study compared the tribological behavior and wear mechanism of three typical metal-based solid self-lubricating coatings under heavy load conditions. It was found that Ni-G and Ni-MoS2 coatings failed due to abrasive and delamination wear mechanisms, while Cu-Sn coating primarily exhibited adhesive wear. Ni-G coating and Cu-Sn coating showed the lowest coefficient of friction and wear rate, respectively, under heavy load conditions. The wear resistance of the coating was found to be strongly influenced by mechanical properties, especially plasticity and toughness when designing metal-based solid self-lubricating coatings for heavy load conditions.

Summary: Polyamic acid (PAA) was synthesized using specific monomers and transformed into colorless transparent poly(amide imide) (CPAI) hybrid films. The CPAI hybrid films were prepared by dispersing organoclay STN in CPAI, and the properties were studied based on the dispersed STN content. While some clay were agglomerated, most clays were well-dispersed in nano-size. The best thermomechanical properties were achieved with an STN content of 3 wt%.

Summary: This study investigates the friction between PDMS and SiOx in single asperity sliding contact using AFM. Friction has two dependencies on the normal force: a tensile regime and a compressive regime. Friction in the compressive regime is governed by shear deformation and rupture of junctions, while in the tensile regime, it is also affected by junction elongation. The single SiOx-asperity exhibits stick-slip motion on PDMS in both regimes. Statistical analysis allows determining the energy required to break a SiOx/PDMS junction.

Summary: Eumelanin possesses a well-defined supramolecular structure with at least three distinct particle species. In this study, a protocol for synthesizing pure and stable dispersion of intermediate type-A particles is presented. The aggregation of type-A particles into larger type-B variant can be prevented by strict pH control. The pH influence on the supramolecular buildup is investigated using various techniques. The results demonstrate that it is possible to inhibit the aggregation of eumelanin substructures and access them in the form of a stable dispersion.

Summary: In this study, 2-amino-5 mercapto-1,3,4-thiadiazole (ATT) was used as an intercalating agent to prepare ATT/BNNS nanofillers via a liquid-phase assisted ultrasound method. TEM results showed that ATT successfully exfoliated BNNS and reduced agglomeration. The WEP ATT/BNNS coating exhibited the best protective performance under saline immersion due to the combined action of ATT inhibitor and BNNS physical barrier.
