Surfactants are one of the most important products in the chemical industry and are used in a wide range of applications such as automobile oils, pharmaceuticals, kitchen and household cleaners, and drilling muds used in oil exploration. The design and development of surfactants with high surface activity has been a hot topic in the field of physical chemistry. In recent decades, Gemini surfactants have been developed. It consists of three parts, ie, hydrophilic and lipophilic. Base and linking groups, this different structure promotes them to have different physicochemical properties than common surfactants. However, combining a polymer surfactant with a tanning surfactant not only changes the physicochemical properties of the polymer surfactant, but also results in lower surface tension and critical micelle concentration, and it can also control its structure to suit different applications. Claim.
So far, no one has explicitly proposed the structure of a polymer twin surfactant. Therefore, it is of great significance to synthesize different structural polymer surfactants. The functional and composite materials research team of the Fine Chemical Engineering Center of the Xinjiang Institute of Physics and Chemistry, Chinese Academy of Sciences proposed a new idea for the design of a dimeric terpolymer surfactant based on RAFT polymerization. The results show that the RAFT polymerization can precisely control macromolecular polymerization. The structure of the material is such that it reaches the desired molecular weight and the hydrophobic hydrophilic end.
Researchers designed the synthesis route of the polymer neoactive surfactant acrylic acid-acrylate, examined the effects of reactant molar ratio, RAFT reagent content, etc. on the polymerization, and characterized the product using infrared, nuclear magnetic and other methods, and The properties of the water-air interface and the micelle structure were measured and analyzed. The double-terpolymer terpolymer surfactants based on RAFT polymerization have good application prospects in the fields of daily chemical industry, pharmaceuticals, petrochemicals, environmental engineering and biotechnology.
The results of this study have been published online in the Journal of Surfactant and Detergent, and related work has been funded by the National “Thousand People Project†- Xinjiang Project and the National Natural Science Foundation of China.
