Findings on Materials Research Detailed by Investigators at Toyo University (Cationic ring-opening polymerization of lactones onto chemically modified single layer graphene oxide)

By a News Reporter-Staff News Editor at Journal of Technology -- Current study results on Materials Research have been published. According to news reporting out of Kawagoe, Japan, by VerticalNews editors, research stated, "The introduction of the acyl perchlorate groups on the surface of single layer graphene oxide was achieved via the reaction of silver perchlorate to alkyl chloride groups, which were attached to oxygen-containing functionality of single layer graphene oxide. Ring opening polymerization of beta-propiolactone, gamma-butyrolactone, delta-valerolactone, s-caprolactone was conducted in a graft-from mechanism to the single layer graphene oxideCFI-2FC104- groups."

Our news journalists obtained a quote from the research from Toyo University, "Without such groups, single layer graphene oxide by itself was found not to support ring-opening polymerization; graphene oxide was not found to exhibit a carbocatalyst effect. Thermogravimetric analysis showed that the grafting efficiency was around 10 wt% for each lactone and improved the oxidative resistance over that of pure single layer graphene oxide."

According to the news editors, the research concluded: "Transmission Electron Microscope images revealed that single layer graphene oxide contained numerous dark contrast nanoparticles across the surface, corresponding to the formation of silver oxide from the use of silver perchlorate."
