Chitin, a fascinating biopolymer found in living organisms, fulfills current demands of availability, sustainability, biocompatibility, biodegradability, functionality, and renewability. A feature chitin is its ability to structure into hierarchical assemblies, spanning the nano- macroscales, imparting toughness resistance (chemical, biological, among others) multicomponent materials as well adding adaptability, tunability, versatility. Retaining inherent structural characteristics colloidal features dispersed media has been central use, considering it building block for construction emerging materials. Top-down designs have reported differentiate from traditional molecular-level, bottom-up synthesis assembly material development. Such topics are focus this Review, which also covers origins biological their influence on morphological physical-chemical properties. We discuss recent achievements isolation, deconstruction, fractionation nanostructures varying axial aspects (nanofibrils nanorods) along with methods modification functional highlight role nanochitin native architecture component subjected multiscale interactions, leading highly dynamic structures. introduce most advances applications nanochitin-derived industrialization efforts, following green manufacturing principles.

Structural Color from Cellulose Nanocrystals or Chitin Nanocrystals: Self-Assembly, Optics, and Applications

Chemical Reviews, Год журнала: 2023, Номер 123(23), С. 12595 - 12756

Опубликована: Ноя. 27, 2023

Widespread concerns over the impact of human activity on environment have resulted in a desire to replace artificial functional materials with naturally derived alternatives. As such, polysaccharides are drawing increasing attention due offering renewable, biodegradable, and biocompatible feedstock for nanomaterials. In particular, nanocrystals cellulose chitin emerged as versatile sustainable building blocks diverse applications, ranging from mechanical reinforcement structural coloration. Much this interest arises tendency these colloidally stable nanoparticles self-organize water into lyotropic cholesteric liquid crystal, which can be readily manipulated terms its periodicity, structure, geometry. Importantly, helicoidal ordering retained solid-state, an accessible route complex nanostructured films, coatings, particles. review, process forming iridescent, structurally colored films suspensions (CNCs) is summarized mechanisms underlying chemical physical phenomena at each stage explored. Analogy then drawn (ChNCs), allowing key differences critically assessed strategies toward coloration presented. progress translating technology academia industry summarized, unresolved scientific technical questions put forward challenges community.
