This review focuses on an emerging class of controlled radical polymerization named Organometallic-Mediated Radical Polymerization (OMRP). The latter is based on the temporary deactivation of the growing radical species by a transition metal complex and the reversible formation of a carbon-metal covalent bond. Initially developed with cobalt complexes, OMRP has extended to several metals today. As highlighted here, the choice of the metal, the structure of ligands, temperature, and additives deeply affect the course of the polymerization and its mechanism. Macromolecular engineering opportunities offered by OMRP are also described, as well as practical applications sustained by the resulting polymer materials. [less ▲]

The huge research effort devoted to the chemical modification of CNTs by grafted macromolecules is driven by the need to enhance their affinity for a variety of environments, a necessary step for designing advanced nanomaterials. This chapter aims at reviewing the until now investigated “grafting to” methods used for the surface modification of carbon nanotubes (CNTs) by polymers of various functionalities. Two major strategies are emphasized on the basis of the number of needed modification steps. The first technique consists in functionalizing the CNTs surface to promote in a second step the covalent anchoring of polymer chains bearing complementary reactive groups either at one chain-end or along the chain. The second approach is straightforward as result of the ability of the selected polymer to add directly onto the sp2 carbons of the CNTs surface. The major advantage of the “grafting onto” techniques is that the molecular characteristics (molecular weight, polydispersity, functionality,…) of the polymers can be tailored prior to the grafting reaction. Moreover, when using the proper controlled or living polymerization techniques and grafting conditions, polymers of well-defined architecture, functionality and properties can be easily anchored to the CNTs surface, which makes the “on-demand” tuning of the chemical properties of CNTs possible.

This communication will focuse on recent progress in the field of cobalt-mediated radical polymerization (CMRP). For example, the beneficial impact of cobalt complexes on the course of acrylate and vinyl chloride (VC) polymerizations will be discussed. The addition of conjugated unsaturated derivatives, like dienes, fullerenes and carbon nanotubes, onto (co)polymers preformed by CMRP has also been investigated. Similarities and differences between these radical addition processes will be presented as well as the potential applications of the resulting copolymers and carbon based materials for photodynamic therapy (PDT) and electromagnetic interferences (EMI) shielding.

The synthesis of a new pH-sensitive amphiphilic A2B mikto-arm star-shaped aliphatic copolyester (with A = PCL and B = tertiary amine-bearing PCL) with two hydrophobic arms and one hydrophilic arm when protonated at pH = 5.5. The copper mediated azide-alkyne cycloaddition was used for the synthesis of the star copolyester and to impart the pH sensitivity to the hydrophilic arm by grafting of tertiary amine groups onto azide bearing PCL chain. The formation of polymersomes in water at pH 5 was assessed by DLS and TEM analyses. [less ▲]

The use of organo-montmorillonite as nanofiller for the preparation of polymer nanocomposites still attracts a lot of attention both on experimental and industrial scale. In order to enlarge the range of organo-montmorillonites available for this application, supercritical carbon dioxide (scCO2) was used as a medium for the organomodification process. This environmentally friendly solvent showed a great potential to obtain ready-to-use organo-montmorillonite powders. Intercalation with high degrees of exchange was obtained when the surfactants (alkyl ammonium, phosphonium, and imidazolium salts) were in the liquid state at the reaction temperature. The addition of a small quantity of co-solvent enabled the intercalation of solid surfactants, such as those bearing hydroxyl or carboxyl groups. Basal spacings of montmorillonite modified in scCO2 corresponded to those measured for organo-montmorillonite prepared in the wet process. A detailed investigation of the reaction conditions was finally performed in order to up-scale the process. [less ▲]
