AI Technical Summary
Traditional ATRP technology requires strict deoxygenation and is cumbersome to operate. Existing aerobic polymerization technology requires artificial light to drive the reaction, additional substrates, complex polymerization reaction systems, and poor controllability of free radical polymerization reactions, making it difficult to achieve green, low-cost, and large-scale industrial applications.
An aerobic controlled free radical polymerization method driven by sunlight and synergistic organic catalysis is adopted. The nonionic surfactant glucosyl-1-glutamic acid dioleate derivative glucose oxidase and organic photocatalyst work together to consume oxygen in the system, so as to achieve efficient and controlled free radical polymerization without degassing, using natural and clean energy sunlight as the driving force.
It achieves efficient and controllable free radical polymerization under normal air pressure without degassing or the addition of glucose. The polymer has a narrow molecular weight distribution, is easy to operate, is green and environmentally friendly, and is suitable for industrial production.
