In this article we review the current state of knowledge in the field of responsive nanoparticles for aqueous-based systems. The review focuses on the use of stimuli-responsive copolymers that can either self-assemble into 'soft' nanoparticles or that are attached to the surface of solid nanoparticles. We first describe the most common methods for synthesizing the different responsive polymers used in the design of such nanoparticles, highlighting living radical polymerization techniques in particular. Subsequently, we give examples of how copolymers containing such responsive blocks can selfassemble into a wide range of 'soft' structures. We also depict the main techniques for attaching responsive polymers to the surface of solid nanoparticles and list advantages and drawbacks of each. Finally, for both soft self-assembled systems and solid core-polymer shell systems, we show specific examples of these systems used in a varied range of applications including drug delivery, smart emulsifiers, transport across membranes, sensors and coatings.

“…, an α-bromoketone, a dithioester and a hydroxyl-containing group, permits the initiation of a second block by NMP [53], ATRP [54], RAFT [55], and ring-opening polymerization (ROP) [56] processes, respectively. Moreover, such an approach greatly broadens the macromolecular engineering possibilities.…”

“…For example, the sequential CMRP of NVP, and the ROP of caprolactone (CL), leads to interesting copolymers that present a hydrosoluble and biocompatible segment (PNVP), in addition to a biodegradable segment (poly(caprolactone); PCL) [56]. Another good example here is the preparation of a well-defined, pH responsive PVAc-b-PAN-b-P4-VP triblock copolymers by the sequential CMRP of VAc and AN, followed by the NMP of 4-vinyl pyridine (4-VP) [53]. Well-defined PVAc-graft-PS copolymers were also prepared by subsequent cobalt-mediated VAc/vinyl chloroacetate copolymerization and the ATRP of styrene, initiated from the pendant chloride functions [57].…”

Controlled radical polymerization driven by cobalt complexes has emerged over the past decades as a powerful tool for the design of precision polymers. This so‐called Cobalt‐Mediated Radical Polymerization (CMRP) relies on the temporary deactivation of the radical chains by a cobalt complex, which strongly decreases the probability of bimolecular termination reactions. CMRP imparts control to industrially important monomers and allows formation of polymers with predictable molecular weights and well‐defined architectures. This book chapter describes general mechanistic principles, key parameters and synthetic progress of CMRP as well as remaining challenges.

“…As a new CRP technique, cobalt-mediated radical polymerization (CMRP) has recently attracted a considerable amount of attention due to its ability to mediate the polymerization of nonconjugated vinyl monomers, such as vinyl acetate (VAc) and N-vinylpyrrolidone [9][10][11][12][13][14][15][16][17][18]. The combination of CMRP and other CRP techniques can allow the synthesis of block copolymers composed of nonconjugated and conjugated monomers.…”

“…The combination of CMRP and other CRP techniques can allow the synthesis of block copolymers composed of nonconjugated and conjugated monomers. Detrembleur et al [17] synthesized well-defined ABC triblock copolymers via a combination of CMRP and NMP techniques. They first synthesized poly(vinyl acetate)-b-polyacrylonitrile diblock copolymers by CMRP, and then conducted the NMP of the conjugated monomers of styrene (St), n-butyl acrylate, and 4-vinylpyridine (4VP) after the end-functionalization of the diblock copolymers.…”

Well-defined poly(vinyl acetate)-block-poly(4-vinylpyridine) (PVAc-b-P4VP) block copolymers were synthesized for the first time by a combination of cobaltmediated radical polymerization (CMRP) and reversible addition-fragmentation chain transfer (RAFT) polymerization, and were used to prepare PVAc-b-P4VP hairy polystyrene (PSt) particles. PVAc end-capped by a cobalt(II) acetylacetonate complex was first synthesized by the CMRP of vinyl acetate, after which the cobalt complex was modified into a dithiobenzoate group for the RAFT polymerization of 4-vinylpyridine. The hairy PSt particles were synthesized by the dispersion polymerization of St using the PVAc-b-P4VP as both a macro-initiator and a colloidal stabilizer under UV radiation. The average size of PSt particles synthesized with 20 wt.% of PVAc-b-P4VP (M n 0 39,500 g/mol) was 136 nm (CV019.2%). Very small Au nanoparticles were successfully immobilized on the surface of the PSt particles.
