Scientists have developed a versatile subnanometer nanowire adhesive with high strength and reversibility. It exhibits good adhesive performance on various substrates and in different environments, and can be easily recycled and removed.
Adhesives are applied extensively in daily life and industries, and people have developed numerous commercial polymeric adhesives. However, in most cases, these adhesives work on dry surfaces in air and form permanent bonds with the substrates, limiting the applications of adhesives. Inspired by the innate adhesive functions of some animals, such as geckos, spiders, mussels, and clingfish, scientists have developed various adhesive compositions and structures to meet various conditions. Here, we show a versatile subnanometer nanowire (SNW) adhesive with high strength and great reversibility, which could be prepared at a large scale through a facile room-temperature reaction. The SNW adhesive contacts the substrates at multiple sites due to the ultrahigh flexibility, and meanwhile, the multilevel interactions among the SNWs endow them with strong cohesion, so they exhibit good adhesive performance. This adhesive is applicable to various substrates, such as metals, polymers, and glass, and not only possesses good stability at room temperature in air but also is suitable for underwater environments and ultralow temperatures. Moreover, this adhesive could be easily recycled and removed from the substrates without any residue and damage. The SNW adhesive not only inspires the design of hierarchical adhesive structures with new contact modes but also has potential for practical applications.
