Self-assembly of micelles into designed networks

چکیده
The EO20PO70EO20 (molecular weight 5800) amphiphile as a template is to form dispersed micelle structures. Silver nanoparticles, as inorganic precursors synthesized by a laser ablation method in pure water, are able to produce the highly ordered vesicles detected by TEM micrography. The thickness of the outer layer of a micelle, formed by the silver nanoparticles interacting preferentially with the more hydrophilic EO20 block, was around 3.5 nm. The vesicular structure ensembled from micelles is due to proceeding to the mixture of cubic and hexagonal phases.

Orthogonal self-assembly of low molecular weight hydrogelators and surfactants.
The concurrent self-assembly of new 1,3,5-trisamide-cyclohexane-based low molecular weight hydrogelators and various surfactants in water leads to the formation of self-assembled fibrillar networks with encapsulated micelles. This prototype system presents an example of orthogonal self-assembly, that is, the independent formation of two different supramolecular structures, each with their own c...

A new type of voltage-responsive comb-like superamphiphilic block polymer PEG113-b-PAA30/FTMA was prepared by the electrostatic interactions of an ionic ferrocenyl surfactant (FTMA) and an oppositely charged double-hydrophilic block polyelectrolyte poly-(ethylene glycol)-b-poly(acrylic acid) (PEG113-b-PAA30) in aqueous solution. An in situ electrochemical redox system was designed to research i...
متن کاملCascade Molecule−Particle−Molecule Self-Assemblies for Fabricating Narrowly Size-Distributed Polymeric Superparticles with a Bicontinuous Nanostructure
Broader developments of nanoscience and nanotechnology require complexly but regularly structured nanoparticles whose fabrications in turn pose a great challenge to nanoscience and nanotechnology. In this communication, we report a new and robust method with a clear mechanism for fabricating narrowly size-distributed superparticles with a bicontinuous inner structure. The processes for the fabr...
متن کاملSelf-assembly of ultra-small micelles from amphiphilic lipopeptoids.
Poly(N-substituted glycine) "peptoids" constitute a promising class of peptide-mimetic materials. We introduce the self-assembly of lipopeptoids into spherical micelles ca. 5 nm in diameter as well as larger assemblies by varying the peptoid sequence design. Our results point to design rules for the self-assembly of peptoid nanostructures, enabling the creation of stable, ultra-small peptidomim...
متن کاملRevealing and tuning the core, structure, properties and function of polymer micelles with lanthanide-coordination complexes.
Controlling self-assembly processes is of great interest in various fields where multifunctional and tunable materials are designed. We here present the versatility of lanthanide-complex-based micelles (Ln-C3Ms) with tunable coordination structures and corresponding functions (e.g. luminescence and magnetic relaxation enhancement). Micelles are prepared by charge-driven self-assembly of a polyc...
