Hydrophobic-electrostatic balance driving the LCST offset aggregation-redissolution behavior of N-alkylacrylamide-based ionic terpolymers [PDF]

, 2009
A series of random terpolymers composed of N-isopropylacrylamide (NIPAAm), 2-acrylamido-2-methyl-1-propanesulfonic acid (AMPS), and N-tert-butylacrylamide (NTBAAm) monomers were synthesized by free radical polymerization.

Coacervate Droplet Sequestration of Heterogeneous Nanoplastics With Elastin‐Like Polypeptides

Angewandte Chemie, EarlyView.
Phase‐separated polypeptide droplets captured incidental nanoplastics as a reusable nanoplastic sink. The engineered droplets selectively partitioned nanoplastics and exhibited unique interactions depending on droplet type and nanoplastic identity, establishing biopolymer coacervates as a potential platform for nanoplastic characterization and removal.

Kosmotropic effect leads to LCST decrease in thermoresponsive polymer solutions [PDF]

The Journal of Chemical Physics, 2018
We study the phenomena of decrease in lower critical solution temperature (LCST) with addition of kosmotropic (order-making) cosolvents in thermoresponsive polymer solutions. A combination of explicit solvent coarse-grained simulations and mean-field theory has been employed.

Effect of Anionic Structure on the LCST Phase Behavior of Phosphonium Ionic Liquids in Water

, 2018
To shed light on the mechanism of lowest critical solution temperature (LCST) phase behavior, the phosphonium-based ionic liquids (ILs) with different anions ([CF3COO]−, [CH3COO]−, and [PF6]−) were chosen and studied in this work by molecular dynamics ...
