Abstract
Low molecular weight dual responsive polymers, after purging with CO2, become polyelectrolytes with high osmolality, which can be used as draw solutes for seawater desalination. These polymers precipitate above their Lower Critical Solution Temperature (LCST) after removal of CO2 via purging with inert gas for ease of recovery and reuse.
摘要
低分子量双重响应聚合物在经过二氧化碳吹扫后，成为具有高渗透压的聚电解质，可作为海水淡化的汲取剂。这些聚合物在去除二氧化碳后，通过惰性气体吹扫，其低于临界溶液温度（LCST）会沉淀出来，便于回收和再利用。
