At a time when global consumption is upgrading and the concept of 'green sustainability' is deeply penetrated, the daily chemical industry is accelerating to get rid of the limitations of traditional synthetic raw materials and iterate in the direction of natural safety, advanced efficacy, low carbon and environmental protection. As a new functional material derived from natural biomass, nanocellulose has quietly become the core force driving the innovation of daily chemical products with its unique nanoscale structure, excellent biocompatibility and designable interface properties, bringing gentle and efficient experience upgrades to skin care products, toiletries, makeup and other categories, and is more in line with the current consumers' core demands for 'clean, safe and sustainable'. Among them, Nanjing Tianlu Nano Technology Co., Ltd. is deeply involved in the field of nanocellulose, relying on mature preparation technology and precise scene adaptation capabilities to promote the large-scale application of this green material in the field of daily chemicals, allowing natural technology to truly empower product upgrades. 1. Nanocellulose: Nanocellulose, a high-performance bio-based material derived from nature and hidden in details

From nano-bio intelligent manufacturing to full life cycle closed loop, the competition in green packaging has entered a new stage of 'hard-core technology competition' - as the global plastic ban continues to escalate and the demand for precision protection and intelligent response of packaging materials in the high-end field continues to iterate, the shortcomings of traditional degradable materials with 'weak performance and single function' have become increasingly prominent, and breakthroughs in microbial synthesis technology have made bacterial cellulose (BC) a 'game-breaker' in the field of high-end green packaging. This kind of nanoscale bio-based material synthesized by microorganisms does not need to rely on plant resources. With its naturally formed three-dimensional network nanostructure and precisely controllable mechanical properties, combined with the empowerment of cutting-edge technologies such as atomic layer deposition and gene editing, it not only achieves a two-way breakthrough of '100% degradability' and 'high-end performance', but also builds a full-chain green system of 'biosynthesis-functional modification-scenario application-component recycling' to

As a new bio-based material, nanocellulose has shown broad application potential in many fields due to its inherent advantages such as renewable, degradable, high specific surface area, and excellent mechanical properties. However, the surface of natural nanocellulose is rich in hydrophilic hydroxyl groups, which easily absorbs water and swells, and is difficult to be compatible with non-polar materials, which greatly limits its application in scenarios such as waterproofing, oil-proofing, and oily wastewater treatment. Giving nanocellulose hydrophobicity through scientific modification and preparation processes can effectively expand its application boundaries and achieve high-value utilization of materials. It is also a current research hotspot and industrial development focus in the field of nanomaterials. The following is a detailed introduction to the core preparation technology, process points and application directions of hydrophobic nanocellulose based on the industry's cutting-edge technology and corporate practical experience, providing reference for technology research and development and industrial applications in related fields. 1. Core Principles of Preparation The core of preparation of hydrophobic nanocellulose is to prepare nanofibers through physical, chemical or mechanochemical methods.
