I found the field of Polymer Science very interesting. Saw the article A polyelectrolyte-containing copolymer with a gas-switchable lower critical solution temperature-type phase transition published in 2019.0. SDS of cas: 61-82-5, Reprint Addresses Zhu, SP (corresponding author), McMaster Univ, Dept Chem Engn, Hamilton, ON L8S 4L7, Canada.; Luo, ZH (corresponding author), Shanghai Jiao Tong Univ, Sch Chem & Chem Engn, Dept Chem Engn, Shanghai 200240, Peoples R China.; Zhu, SP (corresponding author), Chinese Univ Hong Kong, Sch Sci & Engn, Shenzhen 518172, Peoples R China.. The CAS is 61-82-5. Through research, I have a further understanding and discovery of 1H-1,2,4-Triazol-5-amine
A thermo-responsive copolymer with a gas-switchable LCST-type phase transition was synthesized by reversible addition-fragmentation chain transfer (RAFT) polymerization of N-isopropylacrylamide (NIPAM) and glycidyl methacrylate (GMA), followed by post-polymerization functionalization with sodium 3-amino-1,2,4-triazole (ATANa). Incorporating ionic moieties provides an elevated cloud point of 61 degrees C. Importantly, both CO2 and SO2 cause a reduction in the cloud point of the polymer solution. The CO2-triggered system can be easily and fully recovered to its initial state by introducing an inert gas (e.g. N-2), whereas the SO2-triggered system shows only partial recovery. The pH-dependent phase transition behaviors confirm that the gas bubbling-induced pH changes contribute to the gas-switchable cloud point of P(NIPAM-co-(GMA-ATANa)). In addition, P(NIPAM-co-(GMA-ATA)) (ATA: 3-amino-1,2,4-triazole), a counterpart of P(NIPAM-co-(GMA-ATANa)), was prepared and the relevant solution phase transition behavior was studied. Its cloud point shift in response to gas bubbling and pH adjustment is opposite to that of P(NIPAM-co-(GMA-ATANa)), indicating that the latter does not result from the protonation of amidine groups. Alternatively, a reversible H+-induced decrease in hydrophilicity was thus proposed. This contribution enriches the family of thermo-responsive polymers by introducing gas-sensitive polyelectrolytes and also broadens the scope of gas-responsive smart materials.
