Cellulose and Chitin Twisted Structures: From Nature to Applications

Abstract Twisted structures are ubiquitous in plants and animals. Cellulose chitin natural polymers that form the structural skeleton of various twisted systems observed across different length scales, ranging from molecular to nano, micro, macro scale. In addition, cellulose helicoidal found be responsible for coloration, enhanced mechanical properties, motion. This review first addresses chitin‐based chiral nanoscale arrangements. Attention is given nanocrystals, water interactions, out‐of‐equilibrium colorful formed by derivatives, chitin's optical properties. The discussion progresses micro millimeter where specific examples presented showcase specialized helical cellulose‐based organizations. chosen illustrate formation helicities, adaptative shapes, movements at varying such as vascular leaf petioles micro‐scale millimeter‐scale tendrils awns Erodium fruits. So far, results indicate significant work should done on systems. much must learned nature produce novel functional materials. aims provide a comprehensive overview state‐of‐the‐art study their potential applications.
