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.

In recent years, a substance called nanocellulose has gradually come into public view. With its unique physical and chemical properties and broad application prospects, it has been hailed as 'the most potential green nanomaterial in the 21st century.' What is nanocellulose? Nanocellulose is a nanoscale functional material extracted from natural cellulose. Natural cellulose widely exists in plants, bacteria and even some marine organisms. It is the most widely distributed and abundant natural polymer organic matter in nature. Nanocellulose is obtained when we treat cellulose through chemical, physical or biological methods to reduce its diameter to between 1 and 100 nanometers and its length from hundreds of nanometers to several micrometers. According to different structures and preparation methods, nanocellulose is mainly divided into three categories: 1. Cellulose nanocrystals (CNC): remove fibers through strong acid hydrolysis
