説明

We fabricated osmotic agents（OAs）with controlled lower critical solution temperature（LCST）for the PRO system utilizing low-grade heat. In this experiment, several kinds of copolymers were synthesized as OAs from hydrophilic and hydrophobic tertiary amine monomers. The LCSTs of the copolymer solutions were controlled from 23.5 to 41.0 ℃ by changing the copolymer composition. The osmotic pressures of the obtained OA solutions dramatically increased in the presence of CO2. The optimum copolymer composition of OA was suggested by the standpoints of LCSTs, high osmotic pressure and easy release of CO2.
