چکیده
The formation of polyion complexes (PICs) comprising thermoresponsive polymers is intended to result in the aggregates that undergo significant structural changes with temperature. Moreover observed modifications might be critically affected by polymer structure and PICs composition. Different block copolymers based on cationic poly(3-acrylamidopropyltrimethylammonium chloride) poly(N-isopropylacrylamide) were synthesized aqueous RAFT/MADIX polymerization at room Addition poly(acrylic acid) a controlled fashion led aggregates. induced temperature characterized differential scanning calorimetry, Nuclear Magnetic Resonance spectroscopy scattering methods. Thermoresponsive when increasing above cloud point block. reversibility these phenomena depends strongly parameters

Polyion Complex Vesicles with Solvated Phosphobetaine Shells Formed from Oppositely Charged Diblock Copolymers
Diblock copolymers consisting of a hydrophilic poly(2-(methacryloyloxy)ethyl phosphorylcholine) (PMPC) block and either a cationic or anionic block were prepared from (3-(methacrylamido)propyl)trimethylammonium chloride (MAPTAC) or sodium 2-(acrylamido)-2methylpropanesulfonate (AMPS). Polymers were synthesized via reversible addition-fragmentation chain transfer (RAFT) radical polymerization us...
متن کاملNon-Surface Activity of Cationic Amphiphilic Diblock Copolymers
Cationic amphiphilic diblock copolymers containing quaternized poly (2vinylpyridine) chain as a hydrophilic segment (PIp-b-PNMe2VP) were synthesized by living anionic polymerization. By IR measurement, we confirmed the quaternization of the polymer (PIp-b-PNMe2VP), and determined the degree of quaternization by conductometric titration. The surface tension experiment showed that the polymers ar...
متن کاملMechanistic insights into the formation of InP quantum dots.
This paper examines the molecular mechanism of InP colloidal quantum dot (QD) syntheses. Unlike methods for monodisperse PbSe and CdSe we found that existing InP syntheses result in total depletion of molecular phosphorous species following nucleation, so QD growth is due exclusively to non-molecular ripening. We find that amines inhibit precursor depletion via solvation, and these findings may...
متن کاملPolymersomes: tough vesicles made from diblock copolymers.
Vesicles were made from amphiphilic diblock copolymers and characterized by micromanipulation. The average molecular weight of the specific polymer studied, polyethyleneoxide-polyethylethylene (EO40-EE37), is several times greater than that of typical phospholipids in natural membranes. Both the membrane bending and area expansion moduli of electroformed polymersomes (polymer-based liposomes) f...
متن کاملAggregates in solution of binary mixtures of amphiphilic diblock copolymers with different chain length.
The polydispersity effect of amphiphilic AB diblock copolymers on the self-assembled morphologies in solution has been investigated by the real-space implementation of self-consistent field theory (SCFT) in two dimensions (2D). The polydispersity is artificially obtained by mixing binary diblock copolymers where the hydrophilic or hydrophobic blocks are composed of two different lengths while t...
