Micellization Thermodynamics of Pluronic P123 (EO20PO70EO20) Amphiphilic Block Copolymer in Aqueous Ethylammonium Nitrate (EAN) Solutions
Poly(ethylene oxide)-poly(propylene oxide)-poly(ethylene oxide) (PEO-PPO-PEO) block copolymers (commercially available as Pluronics or Poloxamers) can self-assemble into various nanostructures in water and its mixtures with polar organic solvents. Ethylammonium nitrate (EAN) is a well-known protic ionic liquid that is expected to affect amphiphile self-assembly due to its ionic nature and hydro...
متن کاملMicellization of block copolymers
This article deals with recent progress including the author’s work in the field of block copolymer self-assembly in solution and on solid surfaces. The synthesis methods for producing block copolymers with well-defined structures, molecular weights and composition are outlined with emphasis on ionic and controlled free radical polymerization techniques. A general overview of the preparation, c...
متن کاملCompetition between the micellization and the liquid–liquid phase separation in amphiphilic block copolymer solutions
We have formulated the mixing Gibbs energy density for the micelle phase of an amphiphilic block copolymer solution using mean-field lattice theory. We have found a transition between the micellization and the liquid–liquid phase separation in this solution by comparing the mixing Gibbs energy density for the micelle phase with that for the homogeneous phase. Micellization is preferred over the...
متن کاملSuper-helices self-assembled from a binary system of amphiphilic polypeptide block copolymers and polypeptide homopolymers.
We report here a discovery that amphiphilic polypeptide block copolymers and polypeptide homopolymers are able to aggregate together into super-helical structures of rods and rings, in which polypeptide chains form the core and PEG chains form the shell.
متن کاملAmphiphilic Block Copolymer Nano-micelles: Effect of Length Ratio of the Hydrophilic Block
Block copolymer nano-micelles are especially important in cancer treatment because of their fine dimensions. In this article, three systems of amphiphilic copolymers with similar lengths and different ratios of the hydrophobic and hydrophilic chains are studied using implicit-solvent coarse-grained molecular dynamics simulations. The factor fphil is defined as the ratio of the number...
