Greening, high-end, and functional have become the core development trends of the global new materials industry. In the context of the deepening of the dual-carbon policy and the acceleration of green transformation in various industries, recyclable, high-performance, zero-pollution new biomass materials have become the core starting point to replace traditional petroleum-based materials and resolve the contradiction between industrial environmental protection and performance. Nanocellulose is a new nano-level functional material that is deeply processed from natural biomass resources. With its unique advantages such as natural regeneration, ultra-high mechanical strength, complete biodegradation, and easy functional modification, it breaks through the application limitations of traditional chemical materials, effectively balances product performance upgrades and low-carbon environmental protection needs, and widely empowers green and low-carbon innovation and product value upgrades in packaging medical care, high-end manufacturing, environmentally friendly new energy, light industrial building materials, and other fields. 1. What is nanocellulose? Simply put, nanocellulose is made from natural green biomass raw materials such as wood, bamboo fiber, agricultural straw, etc., through advanced enzymatic purification and mechanical

At present, green, safety and purity have become the core themes of the upgrading of the global daily chemical and personal care industries. With the overall improvement of consumers' awareness of the safety of skin care and care, and the continuous implementation of environmental compliance policies such as the global microplastic ban and the reduction of chemical raw materials, the traditional daily chemical formulation system that relies on synthetic additives, petrochemical-based raw materials, and plastic pearlescent powders has been unable to adapt to the high-quality development needs of the industry. Nanocellulose prepared from biomass such as natural wood and plant fiber is a new green functional substrate that has been rapidly industrialized in recent years. With its excellent biocompatibility, unique nanometer three-dimensional structure and multi-functional formula adaptability, this material can fully cover the mainstream daily chemical tracks such as skin care, cleansing and makeup, and effectively solve the pain points of traditional products such as irritation and sensitization, heavy skin feel, unstable system, and poor environmental protection. It has become the core new material driving formula innovation and green iteration in the daily chemical industry. Nanocellulose used in mainstream applications in the field of daily chemicals is divided into fiber

When traditional chemical materials face environmental bottlenecks and high-end synthetic materials are subject to high energy consumption and non-renewable properties, the new materials industry is ushering in a technological change that 'returns from artificial synthesis to nature.' As the core representative of biomass nanomaterials, nanocellulose has broken through the three core barriers of renewable natural resources, high nano-performance empowerment, and low carbon throughout the life cycle. With a native substrate derived from plants, it has achieved mechanical properties and functional attributes comparable to high-end artificial materials, and has become a core key material for iterative upgrades in the current fields of new energy, biomedicine, green manufacturing, and high-end composite materials. 1. Basic definition of materials Nano-upgraded natural fibers Cellulose is the most abundant natural polymer resource on earth. It is widely found in biomass raw materials such as wood, bamboo fiber, crop straw, cotton and linen, and is the green substrate with the longest history of human application. Limited by micron-scale size and single structural characteristics, traditional cellulose materials have long been limited to papermaking.
