Under the industrial trends of water-based, low-carbon and high-performance, the coatings and polymer composite materials industries are continuing to look for new functional additives that combine reinforcement, rheology control, and green traceability. Nanocellulose (CNF/CNC) relies on its natural biomass source, high aspect ratio, abundant surface hydroxyl groups, and customizable modification characteristics to become a valuable green functional component in coating systems, resins, and elastomer composites. A small amount of addition can simultaneously optimize key indicators such as processing rheology, mechanical strength, and weather resistance. It can replace some traditional synthetic rheology agents and inorganic powder reinforcing fillers to help reduce carbon emissions and upgrade formulas. Value and application in coating systems Nanocellulose plays four major roles in water-based coatings: rheology regulation, anti-sedimentation, film-forming reinforcement, and weather resistance improvement. It is suitable for water-based acrylic, water-based polyurethane, industrial anticorrosive paint, wood paint, architectural coatings, inorganic mineral coatings, functional protective coatings and other systems.

在双碳目标引领下，造纸行业正加速向低碳化、高性能化、功能化方向转型。 As a nanofunctional material derived from natural biomass, nanocellulose has become an important new functional additive and reinforcing substrate in the paper industry due to its renewable, biodegradable, excellent mechanical strength, large specific surface area, and outstanding film-forming barrier properties. It provides new solutions for improving quality, reducing costs, and green transformation of special paper, packaging paper, cultural paper, coated paper, and other categories. Nanocellulose uses wood pulp and agricultural and forestry biomass fibers as raw materials, and is disassembled to the nanometer scale through mechanical dissociation, enzymatic hydrolysis or chemical modification processes. It is mainly divided into two mainstream categories: cellulose nanofibrils (CNF) and cellulose nanocrystals (CNC). The raw materials are derived from plant fibers, which are the most abundant natural polymers on the earth. Different from petroleum-based chemical additives, they are low-carbon, environmentally friendly, and fully compatible with the clean production and recycling development of the paper industry.

Panoramic interpretation of classification, performance and daily chemical applications Under the industry trends of 'pure beauty' and 'sustainable consumption', daily chemical formulas are gradually shifting from traditional materials such as synthetic thickeners, petrochemical emulsifiers, and plastic microbeads to natural, degradable functional raw materials. As a new bio-based nanomaterial made from natural cellulose, nanocellulose is becoming an important choice for formula upgrading due to its unique microstructure and comprehensive properties. 1. What is nanocellulose? Cellulose is the most abundant natural polymer on earth and is widely found in plant cell walls, algae and some bacteria. Nanocellulose refers to a material that has processed natural cellulose through physical, chemical or biological methods until at least one dimension is at the nanoscale (usually 1-100 nanometers). It not only retains the basic characteristics of natural, safe and completely degradable cellulose, but also has the unique high specificity of nanomaterials.
