Abstract
Disclosed is a method for synthesizing antioxidant materials based on transition metal dichalcogenide (TMD) compounds and a technology of preparing a composition using the same. The monolayer TMDs functionalized with an amphiphilic block polymer compound and which is stably dispersed in an aqueous solution are prepared by two methods. The thus prepared monolayer TMDs were proven to exhibit excellent and sustained antioxidant effects and excellent stability to light and heat.
Claims14
Monolayer transition metal dichalcogenides (TMDs) functionalized with an amphiphilic block polymer compound comprising a hydrophilic block and a hydrophobic block,
- wherein the amphiphilic block polymer compound contains polyethylene oxide (PEO) and poly(epsilon-caprolactone)(PCL), and the amphiphilic block polymer compound has the structure formula of following Formula 1:
- wherein m is an integer of 2 to 70 and n is an integer of 100 to 150,
- wherein the amphiphilic block polymer compound has a weight ratio of PCL:PEO of more than 1:1 and 1:20 or less.
