The breakthrough in fluorosilicone oil technology has opened a new chapter in new energy and high-end manufacturing

1.High-temperature resistant fluorine-containing silicone oil contributes to the development of new energy vehicles
The new type of fluorosilicone oil demonstrates outstanding stability in high-temperature environments through molecular structure optimization. The research team adopted the block copolymerization technology of perfluoropolyether and polysiloxane, enabling the material to maintain low viscosity at temperatures above 200℃ and effectively enhancing the heat dissipation efficiency of the thermal management system for new energy vehicle batteries. Experimental data show that the temperature difference of the battery module equipped with this material can be controlled within 2℃, the cycle life is extended by 33%, and the cost is only 1/10 of that of traditional fluorinated liquid. This breakthrough provides crucial support for high-rate fast charging technology. It is expected that related applications will rapidly popularize in 2026 with the implementation of the national safety standards for power batteries.

2. Synthetic process innovation reduces production costs
In response to the high energy consumption problem existing in the traditional preparation process of fluorosilicone oil, researchers have developed a supercritical CO₂ assisted synthesis technology, which has increased the reaction efficiency to 98% and reduced the solvent usage by 90%. By introducing phenyl sesquiciloxane as the branched structure, the freezing point of the material is reduced to -60 ℃, and the thermal decomposition temperature exceeds 350℃, meeting the usage requirements in extreme environments. This atomically economical designed process not only simplifies the production flow but also enhances the product purity to 99.99%, with metal ion residues controlled at the ppb level, laying the foundation for industrial mass production.

3. Application expansion in the aerospace field
In the sealing system of spacecraft, the high-pressure resistance performance of fluorosilicone oil-reinforced composites has been significantly improved. Experiments show that its sealing retention time in an environment of 300℃, 10MPa pressure and strong oxidants has been extended from 15 minutes of traditional materials to more than 2 hours. After the satellite solar panel hinge adopted this material, the volatile loss rate in a vacuum environment was reduced to 0.01% per year, ensuring that the mechanism remained flexible during 15 years of in-orbit operation. In addition, the specially modified fluorosilicone oil film was used as the thermal control coating. After 200 thermal cycles ranging from -180 ℃ to + 150℃, the solar absorption ratio remained stable at 0.85±0.02, becoming the core material of the deep space probe.

4. Upgrading of medical equipment materials
Biocompatibility studies have shown that the protein adsorption capacity of artificial heart valves modified with fluorosilicone oil surfaces has decreased by 87%, and the risk of thrombosis has dropped to 1/5 of that of traditional materials. In the manufacturing of microfluidic chips, as a hydrophobic medium, it can achieve precise manipulation with a single-cell capture efficiency of up to 99.3%, providing a new tool for gene sequencing and cell analysis. Cutting-edge research has also applied it to targeted drug delivery systems. By regulating the length of the fluorine chain, the drug sustained-release cycle is precisely controlled within 72±2 hours, reducing the damage of chemotherapy drugs to normal tissues by 60%.
