Precise Control over the Rheological Behavior of Associating Stimuli-Responsive Block Copolymer Gels
“Smart” materials have considerably evolved over the last few years for specific applications. They rely on intelligent macromolecules or (supra-)molecular motifs to adapt their structure and properties in response to external triggers. Here, a supramolecular stimuli-responsive polymer gel is constructed from heterotelechelic double hydrophilic block copolymers that incorporate thermo-responsiv...
متن کاملSelf-assembly of stimuli-responsive water-soluble [60]fullerene end-capped ampholytic block copolymer.
A well-defined, water-soluble, pH and temperature stimuli-responsive [60]fullerene (C(60)) containing ampholytic block copolymer of poly((methacrylic acid)-block-(2-(dimethylamino)ethyl methacrylate))-block-C(60) (P(MAA-b-DMAEMA)-b-C(60)) was synthesized by the atom transfer radical polymerization (ATRP) technique. The self-assembly behavior of the C(60) containing polyampholyte in aqueous solu...
متن کاملControlled nanogel and macrogel structures from self-assembly of a stimuli-responsive amphiphilic block copolymer.
RAFT polymerization was utilized to prepare an amphiphilic block copolymer containing both hydrophilic and hydrophobic segments. The self-assembly behavior of the block copolymer into nano-scale particulate structures was studied in both water and polar organic solvents. Uniform micelle assemblies were stabilized by reaction within the hydrophobic core, which contained pendant azide groups, thr...
متن کاملA dual location stimuli-responsive degradation strategy of block copolymer nanocarriers for accelerated release.
A new strategy that centers on the incorporation of stimuli-responsive cleavable linkages in dual or multiple locations as in both micellar cores and at polymer/solution interfaces leading to synergistically enhanced release of encapsulated anticancer drugs in cancer cells.
متن کاملPreparation, Characterization and Pharmacodynamic Evaluation of Fused Dispersions of Simvastatin using PEO-PPO Block Copolymer
The solubility enhancement of poorly soluble compounds is an important task in pharmaceutical technology as it leads to better bioavailability and a more efficient application. Fused dispersions (FDs) of simvastatin (SIM) using PEO-PPO block copolymer were prepared which paved the way for the formation of an amorphous product with enhanced dissolution and bioavailability. The accumulative s...
