Hydrophobic modified nanocellulose (HNC) is a material with good dispersion, enhanced mechanical properties and hydrophobic properties obtained by nano- and hydrophobic treatment of natural cellulose. It is mainly used in composite materials, coatings, oil-water separation, drug delivery and other fields. Below are the detailed preparation steps: 1. Pretreatment of cellulose raw materials. In order to make natural cellulose materials suitable for nanoification and further chemical modification, pretreatment is first required: cleaning and removing impurities: Cellulose raw materials (such as wood pulp , cotton, rice husk, etc.) Wash it with water to remove impurities such as resin, sugar, protein, etc. This can be accomplished by acid-base washing, enzymatic lysis, or hot water treatment. Chemical treatment: In order to improve the reactivity of cellulose, acid-base treatment is usually performed. Acid treatment (such as sulfuric acid) can destroy hemicellulose and lignin in cellulose,

To improve the preparation method of nanocellulose (NFC or CNC) requires systematic optimization from multiple aspects such as raw material selection, preparation process, equipment optimization, surface modification, characterization means, environmental protection and sustainability. The following is a detailed explanation: 1. The selection of raw materials and the performance of pretreated nanocellulose depends to a large extent on the quality of the raw materials and the pretreatment method. Raw material selection: Choose high-purity and high crystallinity cellulose sources, such as cotton, wood pulp, hemp, sugarcane bagasse, etc. Agricultural waste (such as straw, corn stalk) and industrial by-products (such as pulp waste) are low-cost, sustainable sources of raw materials. Pretreatment: Delignin: Use alkaline treatment (such as NaOH) or organic solvent method to remove lignin to improve cellulose purity. Dehemicellulose: Remove hemicellulose by acid treatment or enzyme treatment to reduce impurity interference. Bleaching: Use hydrogen peroxide or chlorine to further improve the purity of the cellulose. 2. Optimization of preparation method

The difference between carboxylated modified nanocellulose and nanocellulose is not only reflected in chemical composition and structure, but also in their physical properties, functional properties, stability and application fields. The difference between the two will be explained in detail through a more in-depth comparison. 1. Differences in chemical structure and functional groups Nanocellulose: Chemical structure: Nanocellulose is a nanoscale fiber material extracted from natural cellulose.

Nanocellulose degrades cellulose into nano-scale fibers through chemical or mechanical treatment, with high specific surface area and good mechanical properties. Surface functional groups: Unmodified nanocellulose surface contains a large amount of hydroxyl groups (
