A new rubber antioxidant has won the Gold Medal of the Geneva International Exhibition of Inventions for its patent.

The patented achievement developed by the research team led by young researcher Zhang Yagang - a synthetic method for a new type of high-performance ester-based antioxidant - has recently won the Gold Medal at the 47th Geneva International Exhibition of Inventions, along with the Invention Award presented by the Hong Kong Invention and Innovation Association.

Zhang Yagang is currently employed at the Xinjiang Technical Institute of Physics and Chemistry, Chinese Academy of Sciences. In an interview on the 24th, he stated that the awarded patent innovatively embeds multiple antioxidant groups into a single framework, significantly enhancing antioxidant capacity. Due to its advantages of high efficiency, low coloration, and low toxicity, it is mainly used in lubricants, plastics, rubber, fibers, cosmetics, and other fields, demonstrating excellent application prospects.

Zhang Yagang noted that when the research team applied this antioxidant to lubricants, test data showed that the antioxidant capacity of the same oil product increased by 130% to 150%. "This new antioxidant has excellent compatibility with most organic materials."

It is reported that antioxidants are widely used in industry and daily life because plastics, lubricants, rubber, cosmetics, etc., all undergo oxidative aging during use, and antioxidants can effectively inhibit or delay this oxidation process.

The Geneva International Exhibition of Inventions is co-hosted by the World Intellectual Property Organization, the Swiss Federal Government, etc. This year's exhibition featured more than 1,000 inventions from over 50 countries and regions including the United States, Germany, France, and China, covering fields such as biomedicine, new materials, and energy environmental protection. The awards include Special Jury Prize Gold Medal, Gold Medal, Silver Medal, and Bronze Medal.
