Good Dispersion

A simple one-pot process was developed for the covalent immobilization of atom transfer radical polymerization (ATRP) initiators with quaternized triethylamine moieties on the carboxyl-functionalized multiwalled carbon nanotubes (MWCNTs). The initiator-coupled MWCNTs exhibited good dispersion in water and could be used directly to prepare water-dispersion of polymer-MWCNT hybrids, such as stimuli-responsive poly(N-isopropyl acrylamide)-MWCNT hybrids, via surface-initiated ATRP of N-isopropylacrylamide in an aqueous medium. The present one-pot synthesis of the ATRP initiator-immobilized MWCNTs with good dispersion in water provides an alternative route to the direct preparation of water-soluble polymer-MWCNT hybrids in aqueous media.

Responsive Gels

Temperature-responsive poly(N-isopropylacrylamide) (PNIPAAm) gels were prepared via atom transfer radical polymerization (ATRP), and their mechanical and responsive properties were investigated from the viewpoint of their network homogeneity.

Controllable Size

ABSTRACTSpherical carbon particles (CPs) with controllable size and surface functionalities were prepared via hydrothermal treatment using sucrose as a precursor and then post modification methods. The CPs were prepared in two steps; firstly, dewatering of sucrose molecules at relatively low temperatures and secondly, carbonization at high temperatures. The micro/nano-sized CPs were functionalized by 2-Acrylamido-2-methylpropane sulfonic acid (AMPS), (3-Acrylamidopropyl)-trimethylammonium chloride (APTMACI), and N-isopropylacrylamide (NIPAM) in order to have the corresponding polymers on the surface of CPs. The monomers were polymerized via atom transfer radical polymerization (ATRP) by means of grafted initiator onto the CPs surface. Additionally, copolymer of these monomers was synthesized to introduce additional properties. The stability of the functionalized CPs in different solutions, and pH, temperature responsive behaviors of the newly prepared CP-polymers composite were evaluated.
