“…Both pectin variants are long polysaccharide chains with short side chains, that is, flexible polymers whose conformation are largely dictated by entropic effects. [ 54–56 ] Thus, at higher temperatures, such entropic effects will force the flexible polymer chains more strongly into a coiled‐up, compacted conformation than at RT ( Figure a). To ensure accurate size measurements on the two pectin variants, their concentration is reduced to 0.01% (w/v) (as higher concentrations often lead to increased turbidity of the solution arising from molecular aggregation effects).…”

Wet adhesion is a challenging process that requires successful interactions between the two surfaces of interest. Current adhesives may offer sufficient strength but often contain toxic components. Thus, when the field of adhesion meets bioinspiration, there is lots of potential for finding an innovative solution. Here, inspired by mucilaginous seeds and by using refined fiber structures provided by renewable materials, it is demonstrated how to build a comparably strong wet adhesive system. The process involves the controlled fibrillation of a wood surface followed by the application of a macromolecular coating employing the main component found in mucilaginous seeds. Moreover, the additional introduction of a thermo‐responsive polymer into the system allows for obtaining control over the strength and the compliance of the detachment process. Thus, this study demonstrates how combining renewable materials with a multi‐step coating process offers an environmentally friendly solution that pinpoints a promising path toward bio‐based wet adhesives.
