The following article will review the preparation method of nanocellulose and its application research progress in different fields.

Preparation method of nanocellulose.

There are various methods for preparing nanocellulose, mainly including acid hydrolysis, mechanical crushing and biological methods.

Acid hydrolysis method: This method obtains nanocellulose by acid hydrolysis of plant raw materials such as wood, bamboo, etc. Acid hydrolysis has high production efficiency and product quality, but it will produce a large amount of acidic wastewater, which will have a certain impact on the environment.

Mechanical crushing method: Crush plant fiber raw materials to nano-level through mechanical means. Mechanical crushing has little impact on the environment, but has low production efficiency and is difficult to control product quality.

Biological method: Use microorganisms, such as bacteria, fungi, etc. to convert raw materials into nanocellulose through fermentation or enzymatic decomposition. Biological methods have the advantages of environmentally friendly and renewable, but the current production efficiency and product quality still need to be improved.

Research progress on application of nanocellulose

Special paper manufacturing: Nanocellulose has shown great application potential in the field of special paper manufacturing. By adding nanocellulose, the tensile strength, tear and fold resistance of the paper can be significantly improved. In addition, nanocellulose can also improve the transparency and barrier properties of paper, and improve the flexibility and environmental protection of paper.

Biomedical: Nanocellulose has wide application prospects in the field of biomedical due to its high specific surface area and excellent biocompatibility. For example, nanocellulose can be used to make wound dressings, drug delivery systems, tissue engineering stents, and the like.

Composite materials: Nanocellulose can be used as a reinforcement material for the preparation of high-performance composite materials. Its high crystallinity and high orientation can provide strong interfiber bonding forces, thereby improving the mechanical properties and thermal stability of composite materials.

Sensor: Nanocellulose- based sensors are superior to some sensors made of traditional materials in terms of sensitivity, mechanical properties, stability, specificity and environmental friendliness. Nanocellulose-based sensors have wide application prospects in proximity sensing, pH sensing, electrochemical sensing, glucose sensing and ion sensing detection.

With the development of science and technology and the enhancement of environmental awareness, the application prospects of nanocellulose will be broader. Future research should further explore ways to improve the efficiency and product quality of nanocellulose preparation, expand its application scope, and pay attention to its environmental impact assessment to ensure that while achieving economic benefits, it can also achieve sustainable ecological and social development.
