There is provided herein a dryer polymer substance adapted to pervaporate a fluid (such as water, water vapor or both), the polymer substance includes: a porous support member having a plurality of pores, wherein at least a portion of the pores are filled with a cross-linked co-polymer comprising (i) a cationic monomer and an anionic monomer, (ii) a zwitterionic monomer, or a combination thereof. The substance may include a membrane or a tube. There is further provided herein a process for the preparation of a dryer polymer substance adapted to pervaporate a fluid (such as water, water vapor or both), the process includes impregnating into at least a portion of the pores of a porous support member a solution which comprises: (i) a cationic monomer and an anionic monomer, (ii) a zwitterionic monomer, or a combination of (i) and (ii), graft co-polymerizing the anionic monomer and the cationic monomer and/or the zwitterionic monomer within at least a portion of the pores to form a co-polymer, and cross-linking the co-polymer, such that the pores of the support member are at least partially grafted with a cross-linked co-polymer bound to the support member.
本文提供了一种适用于蒸发流体(如水、水蒸气或两者)的干燥聚合物物质,该聚合物物质包括:具有多个孔隙的多孔支撑件,其中至少一部分孔隙填充有交联共聚物,该共聚物包括(i) 阳离子单体和阴离子单体,(ii) 齐聚物单体,或它们的组合。该物质可包括膜或管。本文还提供了一种用于制备干燥聚合物物质的工艺,该物质适于蒸发流体(如水、水蒸气或两者),该工艺包括将一种溶液浸渍到多孔支撑件的至少部分孔隙中,该溶液包括:(i)阳离子单体和阴离子单体,(ii)齐聚物单体,或(i)和(ii)的组合,在至少部分孔隙内接枝共聚阴离子单体和阳离子单体和/或齐聚物单体以形成共聚物,并交联共聚物,使支撑件的孔隙至少部分接枝与支撑件结合的交联共聚物。
