Gelling agent that gels organic liquids (ionic liquids, liquid crystals, etc.) in trace amounts.
It can gel alcohol, oil, liquid crystals, ionic liquids, fluorinated solvents, etc., at a trace amount (1%), and can change between sol and gel through heating and cooling.
The "gelling agent" developed by Yamaguchi University gels organic liquids in small amounts (1%). The formed organic gel can change between sol and gel through heating and cooling. Examples of organic liquids that can be gelled include alcohols, oils, liquid crystals, ionic liquids, and fluorinated solvents. Additionally, this gelling agent does not contain hydrogen bonds, boasting high chemical stability. The gelling in small amounts allows for immobilization while maintaining the properties of the solvent, such as ionic conductivity, enabling applications in ionic liquid gels, liquid crystal gels, gel electrolytes for fuel cells, and carbon dioxide separation membranes. Structural optimization tailored to needs is also possible. 【Expected Use Cases】 Immobilization of functional organic liquids (liquid crystals, ionic liquids), immobilization of electrolyte solutions for dye-sensitized solar cells, gel electrolytes for fuel cells, immobilization of carbon dioxide separation absorbents, cosmetic materials, oxygen transport materials, ink materials, lubricants, thickening agents. ★Samples of the gelling agent are available! It can be customized according to applications (viscosity, solvents to be gelled, etc.). *For more details, please refer to the PDF document or feel free to contact us.

basic information
So far, we have been developing a substance that can be gelled using low molecular weight compounds: "organic gelling agents." Conventional low molecular weight gelling agents were mostly hydrogen-bonding types, but "organic gelling agents" do not have hydrogen-bonding functional groups, which gives them high chemical stability and allows for long-term storage. By adding a small amount (about 1%) of this gelling agent to the solvent to be gelled, a gel can be formed. Additionally, one of the characteristics is that the solvents that can be gelled include not only alcohol-based solvents but also hydrocarbons, high dielectric solvents (non-aqueous electrolytes), ionic liquids, and fluorinated solvents, providing a wide range of options.
