摘要:
通过共聚合策略在1,2-双(三乙氧基硅基)乙烷(BTESE)中引入4,4'-二(三乙氧基硅基)联苯(BTESBPh)后制备得到复合有机硅膜(BTESE-BPh)。相对于经典的BTESE膜,BTESE-BPh膜拥有较大的孔径,使得其CO2捕集能力得到很大提高。N2吸附-脱附以及气体渗透性能测试证实了复合膜的结构演化。使用该复合有机硅膜分离CO2/N2时,CO2通量达2.49×10-6 mol·m-2·s-1·Pa-1,CO2/N2选择性为22.2,这在CO2捕集应用中表现出极大优势。
Abstract:
The composite organosilica membrane(BTESE-BPh)is developed by the copolymerization reaction between 1,2-bis(triethoxysilyl)ethane(BTESE)and 4,4'-bis(triethoxysilyl)biphenyl(BTESBPh).Compared with the classical BTESE membrane, the BTESE-BPh membrane has a larger pore size, which greatly improves its ability to capture CO2. N2 adsorption-desorption isotherms and gas permeation tests confirms the structural evolution of the composite membrane. For the separation application of CO2/N2, the CO2 permeance reaches 2.49×10-6 mol·m-2·s-1·Pa-1, and the CO2/N2 selectivity approaches 22.2, exhibiting great advantages in CO2 capture applications.
