Abstract
A draw solute for forward osmosis may include a copolymer including a first structural unit, where a temperature-sensitive side chain is graft polymerized, and a second structural unit including a hydrophilic functional group. The temperature-sensitive side chain may include a structural unit for a side chain including a temperature-sensitive moiety. The temperature-sensitive moiety may be represented by Chemical Formula 1, Chemical Formula 2, or Chemical Formula 3: wherein Rand Rare each independently hydrogen or a linear or branched C3 to C5 alkyl group, provided that at least one of Rand Ris not hydrogen, Ris a C3 to C5 alkylene group, and Ris a linear or branched C3 to C5 alkyl group. The draw solute may be used to form an osmosis draw solution for use in a forward osmosis water treatment device and method.
