On the role of interface polymers for the mechanics of natural polymeric composites

Research on the deformation mechanisms of tendons and wood has shown that these tissues deform mostly by shearing of a soft matrix between stiff fibres. For this type of composite to be both strong and tough, tight binding between matrix and fibres is required. Recent results suggest that Nature may have evolved special interface polymers, capable both of binding to the fibres and of forming a matrix. Proteoglycans could play this role in tendons by binding to collagen fibrils with their protein-like ends and by forming an aqueous matrix with their sugar-like ends. Hemicelluloses could play a similar role in the plant cell wall, as they are binding to cellulose fibrils and forming aqueous networks between them. This observation suggests that new biomimetic composites might be developed on the basis of amphiphilic polymers capable of binding to stiff fibres and of forming a gel-like matrix around them.

Physical Chemistry Chemical Physics

Physical Chemistry Chemical Physics (PCCP) is an international journal co-owned by 19 physical chemistry and physics societies from around the world. This journal publishes original, cutting-edge research in physical chemistry, chemical physics and biophysical chemistry. To be suitable for publication in PCCP, articles must include significant innovation and/or insight into physical chemistry; this is the most important criterion that reviewers and Editors will judge against when evaluating submissions. The journal has a broad scope and welcomes contributions spanning experiment, theory, computation and data science. Topical coverage includes spectroscopy, dynamics, kinetics, statistical mechanics, thermodynamics, electrochemistry, catalysis, surface science, quantum mechanics, quantum computing and machine learning. Interdisciplinary research areas such as polymers and soft matter, materials, nanoscience, energy, surfaces/interfaces, and biophysical chemistry are welcomed if they demonstrate significant innovation and/or insight into physical chemistry. Joined experimental/theoretical studies are particularly appreciated when complementary and based on up-to-date approaches.
