Abstract
Unique grafting of the poly(glycidyl methacrylate) from the surface of graphene oxide (GO) with the controllable reduction of GO particles was performed in a single-step reaction using atom transfer radical polymerization technique. The control of the GO surface reduction and modification can be achieved by appropriate selection of the ratio between tertiary amine and GO particle contents. Finely tuned electrical conductivity of the GO-PGMA particles enables simple tailoring of electro-responsive properties of their silicone oil suspensions.

Unique grafting of the poly(glycidyl methacrylate) from the surface of graphene oxide (GO) with the controllable reduction of GO particles was performed in a single-step reaction using atom transfer radical polymerization technique
Very recently we found that electrical conductivity of GO can be finely tuned by adjusting the ratios of tertiary amine to GO and of tertiary amine ligand to copper catalyst during atom transfer radical polymerization (ATRP) [28]
In this study we applied the possible tuning of the GO electrical conductivity during ATRP for preparation of new GO/polymer hybrids applicable as a dispersed phase in ER suspensions
