Tuning of multicompartment micelles from cross-linkable ABC triblock copolymer with the addition of core-forming homopolymer
Multicompartment disks with bumpy edges could be synthesized controllably by dissolving a linear ABC amphiphilic triblock copolymer of polystyrene-b-polybutadiene-b-poly (2-vinylpridine) (PS440-b-PBd1020-b-P2VP114) in selective solvent mixtures of toluene and methanol. The disk size was controllable by the initial copolymer concentration. Diameter of the disks increased with the increase of the...
متن کاملComplex domain architecture of multicompartment micelles from a linear ABC triblock copolymer revealed by cryogenic electron tomography.
Cryo-electron tomography of raspberry-like multicompartment micelles formed by a linear ABC triblock copolymer in water revealed that the fluorocarbon domains may be dispersed all over the hydrocarbon core.
متن کاملHydrogen peroxide-responsive micelles self-assembled from a peroxalate ester-containing triblock copolymer.
A novel ABA triblock copolymer by using peroxalate esters as linkages was synthesized. In water, this amphiphilic copolymer self-assembled into micelles which were used as drug delivery carriers. When stimulated with hydrogen peroxide, the micelles disassembled to release drugs since the responsive peroxalate ester linkages would be cleaved after the reaction with hydrogen peroxide.
متن کاملCoaxial nanotubes of stimuli responsive polymers with tunable release kinetics.
Stimuli responsive polymeric (SRP) nanotubes have great potential as nanocarriers of macromolecules due to their large surface areas and release mechanisms that can be activated externally. In this work, we demonstrate vapor phase synthesis of coaxial nanotubes with layers of different SRP polymers for improved release kinetics. Temperature responsive poly(N-isopropylacrylamide) (pNIPAAm), pH r...
متن کاملWet-Spun Stimuli-Responsive Composite Fibers with Tunable Electrical Conductivity
Wet-spun stimuli-responsive composite fi bers made of covalently crosslinked alginate with a high concentration of single-walled carbon nanotubes (SWCNTs) are electroconductive and sensitive to humidity, pH, and ionic strength, due to pH-tunable water absorbing properties of the covalently crosslinked alginate. The conductivity depends on the material swelling in humid atmosphere and aqueous so...
