Ecological concerns are increasingly important in finding sustainable and efficient ways to transform biomass-derived building blocks into functional pressure-sensitive adhesives (PSAs). PSAs are soft polymeric materials that show permanent stickiness at room temperature and adhere to surfaces via noncovalent forces when light pressure is applied. Richard Vendamme, Nicolas Schüwer, and Walter Eevers review developments in this emerging field, summarize origins and requirements of biobased building blocks, describe the materials science of stickiness, overview recent approaches toward synthetic biobased PSAs, and draw a parallel between renewable synthetic PSAs and nature's selfadhesive glues. They highlight the emergence of a new generation of synthetic PSAs that approach those found in the natural world. DOI: 10.1002/app.40669
