“…16 These factors make ARGET ATRP more cost effective, environmentally friendly and safer than ATRP, making it desirable for the use of large-scale polymer brush synthesis, particularly in industry. ARGET ATRP has shown good results in the synthesis of various polymer brushes, [16][17][18][19] however, we were unable to find prior examples of the synthesis of PMETAC brushes via this route.…”

“…Grafting of polymers from solid substrates by the combination of PDA chemistry and ARGET-ATRP has been firstly reported in our previous work [45,46]. Preparation of grafted polymer-functionalized reduced graphene oxide (rGO) by PDA chemistry and ARGET-ATRP has not been reported by other research groups.…”

In this work, polymethyl methacrylate (PMMA) and polystyrene (PS) with controlled structures would be grafted on graphene material. The hybrid materials were prepared by coating graphene oxide (GO) with polydopamine (PDA) as a reactive underlayer and reducing agent, subsequently, surface-initiated polymerization of monomers (methyl methacrylate, styrene) based on the activators regenerated electron transfer atom transfer radical polymerization (ARGET-ATRP) technique. The polymer brush-modified graphene materials were then incorporated into the PMMA or PS matrix to get polymer nanocomposites with better thermal properties. The results of Fourier transform infrared spectroscopy (FTIR), X-ray photoelectron spectroscopy (XPS), scanning electron microscopy (SEM), transmission electron microscopy (TEM), and thermal gravimetric analysis (TGA) demonstrated that PMMA and PS chains were successfully anchored on the surfaces of functionalized GO sheets. The influence of the grafted polymer brush-modified GO on thermal stability of PMMA and PS was investigated by a simultaneous thermal analyzer. Thermal conductivity of the polymer nanocomposite was determined by a conductive calorimeter. The results showed that thermal stability, glass transition temperature ( T g ), and thermal conductivity of the polymer nanocomposites were obviously improved compared with pure PMMA or PS.

Troxerutin, a naturally occurring flavonoid glycoside, has a variety of beneficial activities characteristic for flavonols, such as strong antioxidant and anti-inflammatory properties. Besides the beneficial effects of troxerutin, limitations such as bioavailability have disrupted its application and prompt scientists to look for effective modification methods. This work presents the synthesis of troxerutin-based macromolecules with lipophilic poly(n-butyl acrylate) (PnBA) star arms via "core-first" procedure in a two-step synthetic route. Troxerutin as a polyphenol structure with ubiquitous reactive hydroxyl groups was for the first time modified with α-bromoisobutyryl bromide to receive an atom transfer radical polymerization (ATRP) initiator with 10 brominated initiation sites. The further step involved the synthesis of novel star-like macromolecules with troxerutin core and PnBA star arms by simplified electrochemically mediated ATRP (seATRP) in an environmentally friendly reaction medium-miniemulsion. Electrolysis under constant current conditions with temporal control was implemented, resulting in well-defined star-like polymers with complete preservation of chain-end functionality after restarting the synthesis. Hydrophobic properties of received troxerutin-based macromolecules were investigated by contact angles (Θ) measurements, followed by the free surface energy (FSE) calculations.
