Recent developments in adhesive technology: a review

Abstract

PurposeThis paper aims to provide an insight into recent developments in adhesive technology.Design/methodology/approachFollowing a brief introduction, this paper discusses recent developments in biomimetic adhesives, the use of nanomaterials and “smart” adhesive technology.FindingsBiomimetic dry adhesive technology has advanced very rapidly in recent years and techniques to mass‐produce these materials are now under development. The use of nanomaterials is being investigated widely and recent research suggests that adhesives with enhanced mechanical, thermal and electrical properties will emerge. Smart adhesives, such as switchable types which can be triggered to bond and de‐bond in response to physical or chemical stimuli are under development and some are already available commercially. These will contribute to product disassembly and recycling.Originality/valueThis paper provides a review of recent R&D into three fields of adhesive technology that are presently attracting strong interest.
