superhydrophobic surfaces with superhigh adhesion is significant in special engineering applications, but an elaborate superhydrophobic structure is difficult at artificial fabrication. In this study, a poly[2,2′-(4,4′-oxybis(1,4-phenylene)− 5,5′-bibenzimidazoles]-polydimethylsiloxane (OPBI-PDMS) membrane is prepared via a facile vapor-induced phase separation method, which exhibits high contact angle of 154.1°, high water adhesion and high acidic resistance for 200 h. The results indicate that the sponge-like hierarchical structure formed on the sticky surface of OPBI-PDMS membrane, which offers high hydrophobic property and high adhesion in air, based on the capillary action and pinning effect. Coupled with the high acid-proof performance, the OPBI-PDMS blending membrane is successfully applied in the controllable transferring of acid droplets.

Self-healing materials are used in various applications because of their capacity to prolong the material’s longevity and durability. Several important properties, including high adhesion force to various surfaces and mechanical robustness have the potential to further expand their application in various fields. In this study, we designed an energy-containing and high-adhesion elastomer (3,5-BTP-PDMS-4), which was fabricated via the click polymerization, that could self-heal at −20 °C. The prepared polymer adhesive exhibited prominent mechanical strength with a high Young’s modulus of up to 17.91 MPa. The material also showed that it could autonomously and completely self-heal and restore its mechanical properties within 6 h at room temperature when the 3,5-BTP-PDMS-4 sample was cut into two separate pieces. Moreover, this material was found to possess a high adhesion force of up to 1.65 MPa on steel, which increased when the temperature was reduced. Furthermore, we prepared TATB-based PBXs using 3,5-BTP-PDMS-4 as a binder because of its energy-containing property and excellent self-healing properties to heal cracks generated during fabrication, transportation and storage. Surprisingly, the TATB-based PBXs achieved complete self-healing at 0 °C and partial self-healing at −20 °C, although the low plastic explosive crystals were detrimental to the material’s self-healing properties. The successful development of a polymer adhesive that has a high-Young’s modulus and can autonomously and completely self-heal could help expand its applications with enhanced versatility in several fields, including military and civil applications.

Low-surface-energy (LSE) materials, such as polytetrafluoroethylene (PTFE), are widely used in industrial applications, due to their exceptional hydrophobicity and chemical inertness. However, achieving strong adhesion to these materials has long posed a significant challenge. In this study, a high-performance adhesive is introduced that successfully overcomes this barrier, achieving an unprecedented bonding strength of up to 3.22 MPa on LSE substrates, the highest reported to date. This breakthrough is attributed to the synergistic effects of dipole–dipole interactions and frictional energy dissipation from the polymer side chains. By employing monomers with pendant side chains, such as poly(propylene glycol) methacrylate (PPGMA), both adhesion and toughness are enhanced without requiring any surface treatments. This adhesive exhibits remarkable versatility, effectively bonding to a variety of substrates, including PTFE, polypropylene (PP), polyethylene (PE), glass, ceramics, and steel. With a simple formulation, straightforward polymerization process, and high optical clarity, this adhesive presents a cost-effective solution with significant potential for diverse industrial applications.
