Direct triblock-copolymer-templating synthesis of ordered nitrogen-containing mesoporous polymers

Nanostructured mesoporous carbons: Tuning texture and surface chemistry

“…Further progressive evaporation of the solvent (increase of the surfactant concentration) would favour the formation of H-bonds between the carbon precursor and the template [83][84][85]. The polymerization rate is easily controlled when phenol is used as carbon precursor in EISA.…”

Facile growth of monocrystalline gold–iron nanocrystals by polymer nanoemulsion

“…The triblock copolymer, poly(ethylene glycol)-block-poly(propylene glycol)-block-poly(ethylene glycol) (PEO-PPO-PEO) shows biocompatibility, non-charging trait, non-toxicity, and aqueous solubility and has been used in emulsion processes as a surfactant, besides the stabilization effect and the role of a reducing agent [17][18][19][20][21]. Making use of the copolymer as the surfactant, we have generated long-term stable, highly crystalline Fe 3 O 4 and Fe 3 O 4 /Au nanocrystals [20].…”

Tunable synthesis and multifunctionalities of Fe3O4–ZnO hybrid core-shell nanocrystals

“…9b belong to the C-H bending vibration and the C-O-C stretching vibration of the ether bonding from the polymer molecules on the nanocrystals, but red-shifted for the former and blue-shifted for the latter relative to the corresponding positions of $1587.2 cm À1 and $1120.5 cm À1 in the pure polymer (Fig. 9a), due to the changes in the elastic constants of the bonds as a consequence of gigantic curvature and forceful interactions [45][46][47][48]. Since the redundant PEO-PPO-PEO molecules were removed by the purification procedure, the phenomena indicate the covering of the PEO-PPO-PEO macromolecules on the surface of the Fe 3 O 4 -ZnO nanocrystals [45].…”
