Control of osmotic pressure through CO ₂ -capture and release facilitated by the lower critical solution temperature (LCST) phase transition of acylated branched polyethylenimine

RSC Advances, 2016
A solution of acylated polyethylenimine absorbs CO 2 at low temperatures and draws water from high-salt saline due to the high osmotic pressure, while it liberates CO 2 after phase separation by mild heating and releases water into low-salt saline.

Influence of cyclodextrin on the UCST- and LCST-behavior of poly(2-methacrylamido-caprolactam)-co-(N,N-dimethylacrylamide)

Beilstein Journal of Organic Chemistry, 2014
The monomer 2-methacrylamido-caprolactam (4) was synthesized from methacryloyl chloride (3) and racemic α-amino-ε-caprolactam (2). Copolymerization of 4 with N,N-dimethylacrylamide (5) was carried out by a free-radical mechanism using 2,2’-azobis(2 ...

Self‐Driving Laboratory Optimizes the Lower Critical Solution Temperature of Thermoresponsive Polymers

Advanced Intelligent Discovery, EarlyView.
A low‐cost, self‐driving laboratory is developed to democratize autonomous materials discovery. Using this "frugal twin" hardware architecture with Bayesian optimization, the platform rapidly converges to target lower critical solution temperature (LCST) values while self‐correcting from off‐target experiments, demonstrating an accessible route to data‐

Color Change of N-Isopropylacrylamide Copolymer Bearing Reichardts Dye as Optical Sensor for Lower Critical Solution Temperature and for Host−Guest Interaction with β-Cyclodextrin

, 2016
With a simple reaction pathway, a polymerizable solvatochromic dye monomer was synthesized. Copolymerization of this dye monomer with NiPAAM leads to formation of a solvatochromic copolymer with lower critical solution temperature (LCST) behavior.

Integration of Liquid Handling Robotics, Turbidimetry, and Machine Learning Toward Inverse Design of Lower Critical Solution Temperature Polymer Formulations

Advanced Intelligent Systems, EarlyView.
An integrated OT‐2/plate reader platform automates LCST cloud point measurement of NIPAM‐co‐DMAEMA copolymers across high‐dimensional formulation spaces. Machine learning trained on the resulting high‐throughput datasets achieves R2 up to 0.96 and enables inverse design of polymer formulations to target transition temperatures with <1% error.
