“…Under acidic conditions, i.e., pH < 3.94, O/W emulsion could be stabilized as a result of the protonation of DMAEMA unit, making the emulsifier surface more hydrophilic. When pH was adjusted to more neutral or basic conditions, i.e., pH > 5.80, deprotonation of DMAEMA unit could promote the formation of more lipophilic surface, so the phase inversion from O/W to W/O was observed. Nevertheless, as pH elevated over 9.86, the stability of emulsions significantly decreased and even demulsification occurred due to the disintegration of micelles.…”

An efficient macromolecular emulsifier as water‐tolerant antifogging coating based on coumarin‐containing copolymeric micelles is reported. Compared to the previous work using poly(methyl methacrylate‐co‐2‐(dimethylamino)ethyl methacrylate), coumarin unit in copolymer‐based coating can be photo‐crosslinked under UV light to form an interchain network, successfully avoiding the use of chemical crosslinking agents.

Surface-initiated atom transfer radical polymerization (SI-ATRP) is a powerful tool that allows for the synthesis of organic–inorganic hybrid nanomaterials with high potential applications in many disciplines. This review presents synthetic achievements and modifications of nanoparticles via SI-ATRP described in literature last decade. The work mainly focuses on the research development of silica, gold and iron polymer-grafted nanoparticles as well as nature-based materials like nanocellulose. Moreover, typical single examples of nanoparticles modification, i.e., ZnO, are presented. The organic–inorganic hybrid systems received according to the reversible deactivation radical polymerization (RDRP) approach with drastically reduced catalyst complex concentration indicate a wide range of applications of materials including biomedicine and microelectronic devices.

An amphipathic spiropyran-based random copolymer P(SPMA-co-DMAEMA) was synthesized by atom transfer radical polymerization, and the resulting copolymer was characterized by means of 1 H nuclear magnetic resonance spectroscopy, Fourier transform infrared spectroscopy, and gel permeation chromatography. The self-assembly behaviors and morphology transition were systematically investigated under single and combined external environmental stimuli by transmission electron microscopy. With coumarin 102 as the model drug molecule, the selfassembly micelles were used to control drug loading, release, and re-encapsulation to some extent. The characterization results indicated the successful preparation of the spiropyran-based random copolymer P(SPMA-co-DMAEMA). The external stimuli had some influences on the morphology of the self-assembly aggregate, and the 'schizophrenic' behavior was interestingly found in this work. The drug release experiments showed the reversible loading and release process up to a point, which might expand the potential application domain of the amphiphilic spiropyran-based random copolymer in drug delivery.
