With the continuous development of green materials and functional materials technology, structural color (Structural Color) has gradually become an important direction in the research of new generation optical materials. Different from traditional coloring methods that rely on chemical pigments or dyes, structural color is a color formed by the reflection, diffraction and interference of light by the micro-nanostructure inside the material. Therefore, it has the advantages of environmental protection, stability and controllability. In recent years, the natural bio-based material **Nanocellulose** has shown great application potential in the field of structural color materials due to its unique nanostructure and excellent self-assembly properties. 1. Basic principles of structural color Structural color is an optical phenomenon produced by the microstructure of materials. Its color comes from the interaction between light and periodic structures, rather than the color produced by the absorption spectrum of chemical pigments. Many creatures in nature use structural colors to create bright visual effects, such as butterfly wings

1. What is a thixotropic modifier? In industrial systems such as coatings, daily chemicals, pesticide suspensions, inks, and composite materials, thixotropic modifiers (Thixotropic Rheology Modifier) ​​are an important functional additive used to regulate the rheological properties of the system. Its main function is to adjust the viscosity of the system, prevent solid particles from settling, improve system stability, and improve construction or use performance. An ideal thixotropic system usually exhibits: high viscosity in a static state, reduced viscosity when subjected to shear, and rapid recovery of structure after shearing is stopped. This structural recovery ability directly determines the stability and user experience of the product. In recent years, with the increasing demand for green materials and sustainable development, nanocellulose (Nanocellulose) has gradually become a new high-performance thixotropic regulating material. 2. Structural advantages of nanocellulose Nanocellulose is prepared from natural cellulose through mechanical, chemical or biological methods.

What is nanocellulose? Nanocellulose is a type of nanostructured material obtained by processing natural cellulose (such as wood pulp, cotton, agricultural waste, etc.) through physical, chemical or enzymatic methods. Its diameter is usually 5–100 nm, and its length can reach hundreds of nanometers to several micrometers.

1. Overview of Nanocellulose Nanocellulose (Nanocellulose) is a nanoscale functional material prepared from natural plant fibers through processes such as high-pressure homogenization, TEMPO oxidation or enzymatic defibration.

1. Basic structural advantages and barrier properties of nanocellulose Nanocellulose (Nanocellulose) is a nanoscale fiber material obtained by dissociating natural cellulose through mechanical methods, TEMPO oxidation or enzymatic processes. It mainly includes cellulose nanofibers (CNF) and cellulose nanocrystals (CNC). Its diameter is usually 5–50 nm, its length can reach several microns, and it has an ultra-high aspect ratio and a highly crystalline structure. The fundamental reason why nanocellulose has excellent barrier properties is: high crystallinity structure - the molecular chains are arranged regularly, making it difficult for gas molecules to penetrate the dense hydrogen bond network - forming a high-density two-dimensional/three-dimensional network structure and high specific surface area - improving the interface interaction and enhancing the density of the composite film 'Tortuous Path Effect' - the gas or water vapor diffusion path is significantly extended. In the dry state, nanofibers

In the context of the rapid development of bio-based materials, bacterial cellulose (BC), as a natural polymer material synthesized by microbial fermentation, is moving from laboratory research to large-scale application. Compared with plant cellulose, bacterial cellulose has significant advantages in purity, microstructure and performance stability, and is an important research direction in the current field of functional materials. 1. The formation mechanism and structural nature of bacterial cellulose. Bacterial cellulose is mainly secreted and synthesized by cellulose-producing bacteria such as Komagataeibacter xylinus under aerobic conditions. Its molecular structure is the same as that of plant cellulose, which is a linear polysaccharide connected by β-1,4-glucosidic bonds, but its formation process is different: bacteria directly polymerize and extrude glucose during the fermentation process to form nanoscale fibers, which are then self-assembled to form a three-dimensional network structure. This 'in-situ nanofabrication
