摘要: This work reports the transport of carbon dioxide, oxygen, and nitrogen in amorphous membranes vulcanized natural rubber reinforced with regenerated cellulose. The values permeability coefficient composites 25% cellulose, measured at 25 °C 15 cmHg pressure, are roughly one-third those same conditions for these gases rubber. isotherms representing variation both diffusion coefficients pressure present a relatively sharp increase region low pressures, attributed to changes free volume. analysis characteristics terms free-volume theory suggests that gas is severely hindered cellulose phase cellulose–rubber interphase composites. © 2000 John Wiley & Sons, Inc.
