An ironand methyl methacrylate (MMA)-based electrochemically mediated atom transfer radical polymerization (eATRP) system was developed for the first time. Kinetic behaviors, including the effect of applied potential and catalyst loading, were systematically investigated. Results indicated that with more negative electrode potential, the polymerization rate increased until the mass transport li...

Hydrophobic interactions have been studied in detail the past based on hydrophobic polymers, such as polystyrene (PS). Because fluorinated materials relatively low surface energy, they often show both oleophobicity and hydrophobicity at macroscopic level. However, it remains unknown how fluorination of polymer influences microscopic In this work, we synthesized PS fluorine-substituted (FPS) by ...

An ethoxy-bridged dinuclear indium catalyst was used for the ring opening polymerization of the cyclic ester β-butyrolactone to form the biodegradable polyester poly(hydroxybutyrate) (PHB). The catalyst shows remarkable activity and control during polymerization, allowing for formation of diblock polymers. Addition of high ratios of alcohols to the catalyst leads to fast chain transfer and immo...

The monolithic materials of reduced graphene oxide (rGO) can be used successfully in CO2 adsorption. Here, the incorporation CeO2 particles with and without polymer brushes grafted from showed that structural properties could changed, affecting adsorption CO2. Polymer (1) poly(acrylic acid) (PAA), (2) poly(vinyl caprolactam) (PVCL) (3) poly[(2-(methacryloyloxy)ethyl) trimethylammonium chloride]...
