Strategy for self-assembly of the poly(9,9-dihexylfluorene) to microspheres: optimizing the self-assembling conditions

Direct formation of nano-objects via in situ self-assembly of conjugated polymers

“…84 Some of these polymers may be well suited for INCP, such as oligo( p-phenylene ethynylene) (which forms nanowires) 85 and poly(9,9-dihexylfluorene) (which forms spherical nanoparticles and nanowires). [86][87][88][89] Other polymers may be more challenging to adapt to INCP, such as P3HT (which was previously utilized as the soluble block in INCP), despite its ability to form nanofibers and 2Drectangles using other methods. 61,62,[90][91][92][93][94][95] Similarly, poly(3octylthiophene) (which forms nanowires) 96 and poly [3-(2,5,8,11-tetraoxatridecanyl)thiophene] (which forms nanoribbons) 97 would also be challenging due to their side chains which provide good solubility.…”

Bio-Inspired Polymeric Structures with Special Wettability and Their Applications: An Overview

“…Superhydrophilic surfaces play increasingly important roles in human life: superhydrophilic meshes for oil/water separation [ 96 , 125 , 126 , 127 , 128 ], anti-fogging superhydrophilic glasses [ 129 ], superhydrophilic papers for easy printing [ 130 ], self-cleaning [ 131 , 132 ], anti-biofouling [ 133 , 134 , 135 ], corrosion resistance [ 136 ], friction reduction [ 137 ], etc. As a consequence, a variety of bio-inspired superhydrophilic structures, (i.e., a porous/hierarchical/sponge structure, micro-/nanofibers/pillars/beads/tubes, and polymer coated meshes) [ 59 , 96 , 125 , 128 , 129 , 134 , 135 , 138 , 139 , 140 , 141 , 142 ] have been developed through the techniques of polymerization [ 140 , 143 , 144 ], self-assembly [ 145 ], deposition [ 146 ], immersion [ 125 ], electrospinning, etc. [ 141 , 147 ].…”

“…Thus, new materials that overcome these drawbacks are in high demand. Polymers such as PDMS (polydimethylsiloxane), PU (polyurethane), and polystyrene have shown excellent flexibility and stretchability and are regarded as ideal candidates for superhydrophilic materials [ 140 , 141 , 142 , 143 , 144 , 145 , 146 , 147 , 148 ]. Xu et al [ 127 ] developed a three-dimensional hierarchical oil/water separation sponge, which produced a transparent milk-like oil/water emulsion over a period of 5 min, by mixing 3% ( w/w ) chitosan with 10% ( w/w ) polyacrylamide (PAM) as a pre-gel solution ( Figure 9 f).…”

One-step preparation of conjugated homopolymer sub-microspheresviaa controllable supramolecular approach toward optoelectronic applications

“…24,25 As a result of high planarity, rigidity and hydrophobicity, CPs chains tend to pack together and self-assemble into anisotropic nano-aggregates by post-polymerization method, ultimately generate irregular zero-dimensional (0D) nanoparticles or dots, 22,25 one-dimensional (1D) bril, 7 even two-dimensional (2D) layered structures, 26 but structurally isotropic spheres are rarely reported. 27,28 Recently, alternating copolymers with two different p-conjugated components were demonstrated to form well-shaped CPSMs quantitatively with diameters ranging from a few hundreds of nanometres to several micrometres, ascribed to large steric hindrance on their backbone that reduces planarity of the polymers and inhibits anisotropic packed growth. 10 However, up to now, it is rarely post-polymerization method to construct well-dened, widely size-tunable spherical sub-microstructures prepared from pconjugated homopolymer toward potential optoelectronic application, especial colloidal crystal.…”
