Smart polymer gel has good application prospects and global R&D enthusiasm is high

Smart polymer gel is a type of polymer gel, which refers to a smart polymer that swells in a solvent and has a large amount of solvent but does not dissolve. Smart polymer gel can sense subtle changes and stimuli in the external environment, and transmit and amplify signals through molecular circuits to perform external work. Smart polymer gels belong to the category of smart materials. Compared with ordinary gels, smart polymer gels have the capabilities of sensing, processing, execution, identification, self-healing, and environmental strain. Through methods such as molecular design and organic synthesis, they can Give smart polymer gels more and more advanced functions.

In terms of classification, smart polymer gels can be divided into two categories: single-response smart polymer gels and dual-response smart polymer gels. Single-response smart polymer gels include temperature-sensitive, pH-sensitive, and heat-sensitive types. type, light-sensitive type, pressure-sensitive type, etc. Dual-response smart polymer gels include pH+temperature-sensitive type, light+heat-sensitive type, magnetic+heat-sensitive type, etc.

According to the “2023-2027 Smart Polymer Gel Industry Market In-depth Research and Investment Prospects Forecast Analysis Report released by the Industrial Research Center It shows that smart polymer gels are one of the hot spots in polymer scientific research at home and abroad. In foreign markets, smart polymer gel-related companies mainly include Sumitomo Chemical of Japan, BASF of Germany, Sanyo Chemicals of Japan, ConvaTec of the United States, Yoshii of Japan, Tao Chemistry etc.

At present, there are deficiencies in the research, technology and application of smart polymer gels in my country. Compared with the international advanced level, there is still a large gap, and the demand for high-end products still relies on imports. Domestic smart polymer gel R&D institutions mainly include Ningbo Institute of Materials, Chinese Academy of Sciences, Wuhan University, Changchun Institute of Applied Chemistry, Chinese Academy of Sciences, Guangzhou Institute of Chemistry, etc. Related companies include Changchun Yoshihara Biotechnology, Kanglidi Medical, Huizhou Huayang Medical, and Zhuhai Guojia New Materials wait.

Polymer gel is the most representative material. In recent years, with the advancement of technology, polymer gel has gradually developed towards high performance, multi-function, composite and intelligence. In this context, smart polymers Gels are gradually becoming a hot topic in the market. Smart polymer gels are environmentally responsive. Based on their characteristics, smart polymer gels have shown good applications in the fields of artificial muscles, environmental engineering, drug controlled release systems, shape memory, flexible electronics, smart wound dressings, soil moisturizers, etc. prospect.

The preparation process of smart polymer gel is divided into two categories: physical cross-linking method and chemical cross-linking method. Industry analysts said that smart polymer gels are environmentally responsive and have broad application prospects in medical, agricultural, electronics and other fields. , with technological breakthroughs in the future, the application scenarios of smart polymer gels will be further expanded. But overall, as a new material, there are still many challenges in the large-scale application of smart polymer gels.
