摘要：
Membranes comprising chitosan and re-acetylated chitosan for use in desalination and Salinity Gradient Power Vapor Pressure Desalination (SGP-VPD). A thin film composite (TFC) membrane comprising a minimally hydrophilic re-acetylated chitosan outer layer and a substantially hydrophilic chitosan porous support layer for performing desalination and a multi-layer membrane comprising substantially hydrophobic re-acetylated chitosan inner and outer layers surrounding a substantially hydrophilic chitosan porous support layer for performing SGP-VPD.
