Multiple hydrogen bonds endow single-component solvent-free adhesives with high flexibility and self-healing properties

Key Points

• The aim is to create a sustainable, multifunctional adhesive with high flexibility and self-healing capabilities through controlled intermolecular interactions.
• Synthesis of a single-component solvent-free adhesive driven by multiple hydrogen bonds.
• Characterization of adhesive properties including flexibility and self-healing.
• Regulation of intermolecular interactions to improve performance.
• The adhesive demonstrated significant flexibility, exceeding 50% strain without failure.
• Self-healing properties were observed, with a recovery rate of 80% after damage.
• Increased durability was confirmed through multiple adhesion tests.
