【摘要】 研究了聚乙烯醇(PVA)在氢氧化钠催化下与草酸(OA)酯化交联的一种新的膜的制备及性能表征.将PVA与聚偏氟乙烯(PVDF)制成PVA/PVDF交联复合膜,利用红外光谱(IR)表征了交联膜的化学结构.并研究了其作为蒸汽渗透膜分离乙醇-水混合物的分离性能.更多还原

【Abstract】 The preparation and characterization of PVA - OA membranes by crosslink - esterification are described. PVA -OA membranes were prepared by PVA crosslink - esterified with OA at NAOH.The chemical structure of PVA- OA membranes were characterized by IR - spectrometry.The PVA/PVDF composite membranes were used for separation of water - ethanol by vapor permeation.The performances of vapor permeation of the composite membranes were also studied.更多还原
