A series of aromatic polyimide membranes were synthesized using direct polycondensation of various diamines containing flexible ether groups and bulky substituents with various aromatic dianhydrides. It is expected to promote the gas permeability of the polyimide membrane and maintain similarly gas
The sorption and transport of water in nylon 6,6 films as functions of the relative humidity (RH) and temperature were studied. Moisture-sorption isotherms determined gravimetrically at 25, 35, and 45ยฐC were described accurately by the GAB equation. Water-vapor transmission rates were enhanced above
