The CO 2 gas separation performance of aminated reduced graphene oxide (A-rGO) incorporated PEBAX mixed matrix composite membranes, by means of amination heating time and A-rGO loading, is reported. The 5 h of heating time resulted in an essential molecular sieving property for CO 2 separation, thus used in membrane fabrication. The selective PEBAX/A-rGO5 layers were fabricated on top of the polysulfone supporting layer by a dip-coating method. The A-rGO was well-dispersed, the selective and support layers were seamlessly attached. The CO 2 permeability and CO 2 /N 2 selectivity of the PEBAX/A-rGO5 was greater than that of pristine PEBAX. 3 wt% of A-rGO5 loading resulted as the optimum since the gas selectivity decreased at higher loading. The PEBAX/A-rGO5 performance, which was slightly above the Robeson 2008 upper bound of permeability-selectivity relation for CO 2 /N 2 gas separation, shows a promising application for industrial CO 2 gas separation process.

基于还原氧化石墨烯胺化的混合基质复合膜用于 CO2 分离：加热时间和纳米填料负载的影响

报道了通过胺化加热时间和 A-rGO 负载量的结合了 PEBAX 混合基体复合膜的胺化还原氧化石墨烯 (A-rGO) 的 CO 2 气体分离性能。5 小时的加热时间导致CO 2 分离必不可少的分子筛分特性，因此用于膜制造。通过浸涂方法在聚砜支撑层的顶部制造选择性 PEBAX/A-rGO5 层。A-rGO 分散良好，选择性层和支撑层无缝连接。PEBAX/A-rGO5的CO 2 渗透性和CO 2 /N 2 选择性大于原始PEBAX的。3 wt% 的 A-rGO5 负载是最佳的，因为气体选择性在更高的负载下降低。PEBAX/A-rGO5 性能，
