The core of the iterative upgrading of the new materials industry lies in balancing performance breakthroughs and ecological sustainability. Under the multiple industry trends of plastic pollution control, industrial low-carbon transformation, and localization of high-end materials, the performance shortcomings and environmental protection drawbacks of traditional synthetic materials have become increasingly prominent. The industry is in urgent need of large-scale, high-quality green alternative materials. Nanjing Tianlu Nanotechnology Co., Ltd., which has deep roots in Nanjing and focuses on the field of biomass nanomaterials, focuses on the core track of nanocellulose and has been deeply involved in material research and development, green preparation and scenario-based applications for many years. Relying on mature core processes and technology accumulation, we use natural biomass as the base to polish the properties of nano-scale materials, and successfully solve the industry pain point of 'inability to balance environmental protection and performance' of traditional materials. Nanocellulose, which is low-carbon, high-strength, degradable, and multi-functionally modified, can accurately meet the upgrading needs of multiple industries and provide core material support for high-quality, low-carbon development in industrial manufacturing, livelihood consumption, new energy and other fields. 1. Material

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.

In the context of rapid iteration of the green daily chemical and pure beauty industries, natural biomass functional raw materials have become the core breakthrough for the upgrading of daily chemical formulas. Traditional daily chemical formulas are highly dependent on synthetic additives such as acrylics, carbomers, and cellulose derivatives. Although these raw materials can achieve basic functions such as thickening, suspension, and film formation, they generally have shortcomings such as poor system tolerance, sticky skin, easy sensitization, and poor biodegradability. They are difficult to adapt to the current industry development needs for safety, efficacy, and low carbonization. Nanocellulose, as a nanoscale polymer material derived from plant biomass, relies on its unique one-dimensional nanostructure, controllable rheological properties, excellent biocompatibility and environmental friendliness. It can optimize the daily chemical product system from multiple dimensions such as formula stability, skin feel, efficacy utilization, and green attributes. It is currently the new daily chemical functional substrate with the most application potential. This article takes the formulation and application technology mechanism of nanocellulose as the core, from the perspective of structural characteristics, core
