Ionic liquid gels have great application potential and are highly enthusiastic about research and development at home and abroad.

Ionic liquid gel is a new gel material that uses ionic liquid as the dispersion medium and has a three-dimensional cross-linked polymer network structure. Ionic liquid gels not only have the properties of ionic liquids such as conductivity, non-volatility, and thermochemical stability, but also have the environmental responsiveness and network structure of ordinary gels. Based on this, ionic liquid gels are widely used in supercapacitors, lithium batteries, photovoltaic cells, Electrochromic devices, biosensors, functional membrane materials, underwater communications and other fields show great application prospects.

In terms of classification, ionic liquid gels can be divided into three categories: physical, chemical and mixed types. The three-dimensional network structure of physical ionic liquid gels is cross-linked through weak non-covalent interactions; The components of chemical ionic liquid gels are cross-linked through covalent interactions; mixed ionic liquid gels are constructed using organic and inorganic materials. Mixed ionic liquid gels have excellent performance and wider application fields, and are one of the key research directions in this field.

According to the “2022-2027 China Ionic Liquid Gel Industry Market In-depth Research and Development Prospects Forecast Report released by the Industrial Research Center , The starting materials of ionic liquid gels can be divided into monomers, polymers, mixtures, etc. Due to different starting materials, the preparation methods of ionic liquid gels are also different. Currently, the more typical preparation methods include free radical polymerization and casting. method, ionic liquid self-polymerization method, etc.

Ionic liquid gels have broad application prospects. In order to seize market opportunities, many countries around the world have carried out research on ionic liquid gels. In China, ionic liquid gel research institutions include Ningbo Institute of Materials Science, Xi’an Jiaotong University, Institute of Physics and Chemistry, Chinese Academy of Sciences, South China Advanced Institute of Soft Matter Science and Technology, etc. At present, the research hotspots of ionic liquid gels are mostly focused on molecular design, composition-structure-performance relationship, and preparation of functional materials.

Ionic liquid gel has molecular designability. As an electrolyte, ionic liquid gel can be made into any shape with electrode materials, which is conducive to promoting the development of electrochemical devices in the direction of diversification, miniaturization, ultra-thinness and flexibility. However, existing ionic liquid gel electrolytes often have problems such as poor mechanical properties, low lithium ion migration numbers, and unstable electrode interfaces, which limit their practical application to a certain extent. The ionic liquid gel market needs to be further developed in the future.

Industry analysts said that ionic liquid gels have the characteristics of both ionic liquids and gels, and are widely used in underwater communications, biosensors, and energy. Materials, supercapacitors and other fields have huge application potential. Ionic liquid gels have been a hot research topic at home and abroad in recent years. With the in-depth research and advancement of application technology, the application fields of ionic liquid gels are expected to be further expanded in the future, and the industry has good development prospects.
