We report on the grafting of poly(methyl methacrylate) (PMMA) onto the surface of high-density functionalized graphene oxides (GO) through controlled radical polymerization (CRP). To increase the density of surface grafting, GO was first diazotized (DGO), followed by esterification with 2-bromoisobutyryl bromide, which resulted in an atom transfer radical polymerization (ATRP) initiator-functionalized DGO-Br. The functionalized DGO-Br was characterized by X-ray photoelectron spectroscopy (XPS), Raman, and XRD patterns. PMMA chains were then grafted onto the DGO-Br surface through a ‘grafting from’ technique using ATRP. Gel permeation chromatography (GPC) results revealed that polymerization of methyl methacrylate (MMA) follows CRP. Thermal studies show that the resulting graphene-PMMA nanocomposites have higher thermal stability and glass transition temperatures (Tg) than those of pristine PMMA.

“…Secondly, some catalysts such as CuBr are unstable expose to the air and moisture. Therefore, a so-called reverse atom transfer radical polymerization (RATRP) has been developed rapid recently [11][12][13][14][15][16][17]. However, the preparation of welldefined polymer-grafted inorganic particles via RATRP is rarely reported yet [18][19][20].…”

The literature data about the use of catalytic systems and compositions based on iron and its com plexes for the controlled synthesis of polymers via the atom transfer mechanism are generalized and ana lyzed. The effects of the oxidation number of a metal atom, the ligand environment, the structure of a radical initiator, the activating additives, and other factors on the molecular weight characteristics of the polymers and the kinetics of vinyl polymerization are considered.
