摘　　要：Plant cell wall(CW)-like soft materials,referred to as artificial CWs,are composites of assembled polymers containing micro-/nanoparticles or fibers/fibrils that are designed to mimic the composition,structure,and mechanics of plant CWs.CW-like materials have recently emerged to test hypotheses pertaining to the intricate structure–property relationships of native plant CWs or to fabricate functional materials.Here,research on plant CWs and CW-like materials is reviewed by distilling key studies on biomimetic composites primarily composed of plant polysaccharides,including cellulose,pectin,and hemicellulose,as well as organic polymers like lignin.Micro-and nanofabrication of plant CW-like composites,characterization techniques,and in silico studies are reviewed,with a brief overview of current and potential applications.Micro-/nanofabrication approaches include bacterial growth and impregnation,layer-by-layer assembly,film casting,3-dimensional templating microcapsules,and particle coating.Various characterization techniques are necessary for the comprehensive mechanical,chemical,morphological,and structural analyses of plant CWs and CW-like materials.CW-like materials demonstrate versatility in real-life applications,including biomass conversion,pulp and paper,food science,construction,catalysis,and reaction engineering.This review seeks to facilitate the rational design and thorough characterization of plant CW-mimetic materials,with the goal of advancing the development of innovative soft materials and elucidating the complex structure–property relationships inherent in native CWs.
