There have been many studies for poly(ethylene oxide) (PEO) materials due to their versatile applications. However, neat PEO tends to crystallize due to the helical structure of the chains. Poly(oxyethylene methacrylate) (POEM) is an amorphous PEO with a lack of crystallinity but with poor mechanical properties that limit its use in many applications. In order to address these issues, our group reported the synthesis of various amphiphilic graft copolymers and their use in dye-sensitized solar cells, supercapacitors and batteries. It has been well known that a graft copolymer is more advantageous than a block copolymer as it is economical and has a simple synthetic method. For example, the graft copolymer consisting of poly(vinyl chloride)-graft-poly(oxyethylene methacrylate) (PVC-g-POEM) was synthesized via atom transfer radical polymerization (ATRP) with a copper/ligand complex that functions as a reaction catalyst. |
