Cellulose is a natural polymer compound mainly composed of β - glucose units connected by β -1,4-glycosidic bonds, and is the main component of plant cell walls. As one of the most abundant organic polymers on Earth, cellulose not only plays an important role in plant physiological structures, but also has a wide range of applications in industry and daily life. This article will explore the main characteristics and application fields of cellulose. The structural characteristics of cellulose endow it with specific physical and chemical properties The high regularity and crystallinity of carboxymethyl cellulose molecular chains give it high mechanical strength and stability. In addition, a large number of hydroxyl (- OH) groups enable cellulose to form hydrogen bonds, enhancing its low solubility in water, which makes cellulose more stable in humid environments. In addition, the biocompatibility and biodegradability of cellulose are also important features, which makes its impact on the ecological environment relatively small. In terms of applications, cellulose has a wide and diverse range of uses Firstly, in the field of agriculture, cellulose, as a component of some animal feed, enhances the nutritional value of the feed and promotes animal digestion. Secondly, cellulose is widely used in the food industry as a thickener, stabilizer, and emulsifier, helping to improve the texture and freshness of food. In addition, methyl cellulose also holds a place in the pharmaceutical industry as an excipient for drugs, providing excellent release characteristics and bioavailability. Another important application area is the development of cellulose derivatives Through chemical modification, hydroxyethyl cellulose can be converted into derivatives with different functions, such as carboxymethyl cellulose, cellulose ether, etc. These derivatives have been widely used in industries such as cosmetics, plastics, and coatings. Especially in the paper industry, cellulose is regarded as a raw material, and various types of paper and cardboard are produced through chemical and physical processing, demonstrating its importance in resource utilization. The biodegradability of cellulose makes it highly potential for sustainable development Against the backdrop of global concern for environmental protection and renewable resources, the use of ethyl cellulose source materials to manufacture biodegradable plastics has become one of the research hotspots. This type of new material not only reduces reliance on traditional petroleum based plastics, but also helps alleviate environmental pollution problems. In summary, cellulose, as an important natural polymer material, has demonstrated extensive application value in many fields due to its unique chemical and physical properties. Whether in the fields of food, agriculture, pharmaceuticals, or environmentally friendly materials, the potential of cellulose is worth further exploration. In today's society where sustainable development is increasingly valued, the research and application of cellulose will provide more solutions to address environmental challenges.
