“…Amphiphilic polymers, bearing both hydrophobic and hydrophilic molecular components, show unique and specific properties and are quite different from those of homopolymers. Recently, the structures and behaviors of self-assembled amphiphilic polymers have been revealed in detail. , Information related to the macromolecular assembly will provide useful strategies for the design and structural control of the molecular level targeting of functional materials. − Amphiphilic polymers have attracted considerable attention as surfactants due to the coexistence of opposing properties (hydrophobic and hydrophilic) in a single molecule. They enable hydrophobic particles such as carbon nanotubes, metal particles, dyes, or pigments to be efficiently dispersed in aqueous media.…”

Water-soluble amphiphilic polymers containing styrene (St), acrylic acid (AA), or sulfonic acid moieties were synthesized and evaluated as polymeric surfactants for dye dispersions. 2-Acrylamide-2-methylpropanesulfonic acid (AMPS) was employed as a hydrophilic monomer containing a sulfonic acid moiety. The sulfonic acid moieties are effective hydrophilic molecular components adding moderate redispersion properties. Rheology, particle size distribution, surface tension, surface excess (Γmax), minimum area per molecule (A min), and redispersion properties were examined. This is because these factors are important in controlling the physical properties of an ink solution and the quality of printed materials. After the examination of surface parameters, the copolymer using St, AA, and AMPS shows the highest Γmax, indicating that it is most densely packed at the water/air interface. Aqueous solutions of polymers containing an AA moiety exhibit pseudoplastic properties, whereas those containing only a sulfonic acid moiety show a clear Newtonian fluid property. All color dispersions show unimodal particle size distribution and stable dispersion after thermal aging. However, sedimentation of dye particles was observed for polymers containing AMPS. Incorporation of AA and AMPS moieties in the amphiphilic polymer structure is proven to be suitable for the redispersion of dried or solidified ink into aqueous media. Regarding the rheology and the surface parameters, this study has shown that water-soluble polymers with sulfonic acid groups exhibit different properties from those containing acrylic acid. The introduction of sulfonic acid groups into conventional amphiphilic polymers consisting solely of styrene and acrylic acid was found to improve the redispersion properties of the ink. In this study, we demonstrate the potential of water-soluble amphiphilic polymers containing sulfonic acid groups as dispersants for inkjet inks.

“…Self-assembled nanostructured materials built from block polymers have attracted much attention. Block copolymers can self-assemble into ordered assemblies of various shapes, such as micelles and vesicles, according to the properties and proportions of their components [1][2][3]. The development of new functional nanomaterials based on the principle of self-assembly have shown a bright prospect in the field of high technology [4][5][6][7][8].…”

Building novel functional nanomaterials with a polymer is one of the most dynamic research fields at present. Here, three amphiphilic block copolymers of 8-hydroxyquinoline derivative motifs (MQ) with excellent coordination function were synthesized by Reversible Addition-Fragmentation Chain Transfer Polymerization (RAFT) polymerization. The coordination micelles were prepared through the self-assembly process, which the MQ motifs were dispersed in the hydrophobic polystyrene (PSt) blocks and hydrophilic Poly(N-isopropylacrylamide (PNIPAM)) blocks, respectively. The dual-emission micelles including the intrinsic red light emission of quantum dots (QDs) and the coordination green light emission of Zn2+-MQ complexes were built by introducing the CdSe/ZnS and CdTe/ZnS QDs in the core and shell precisely in the coordination micelles through the coordination-driven self-assembly process. Furthermore, based on the principle of three primary colors that produce white light emission, vinyl carbazole units (Polyvinyl Carbazole, PVK) with blue light emission were introduced into the hydrophilic PNIPAM blocks to construct the white light micelles that possess special multi-emission properties in which the intrinsic red light emission of QDs, the coordination green light of Zn2+-MQ complexes, and the blue light emission of PVK were synergized. The dual and multi-emission hybrid micelles have great application prospects in ratiometric fluorescent probes and biomarkers.
