原始语种摘要: Abstract(#br)Biphenyl-based covalent triazine framework (CTF) particles, as a new class of organic porous materials, were incorporated into polydimethylsiloxane (PDMS) for the fabrication of a high performance pervaporation membrane for n -butanol ( n -BtOH) recovery. Increasing the CTF loading remarkably enhanced both the flux and the separation factor of the membrane. This was ascribed to the strongly hydrophobic, highly porous and mesoporous structure of CTF providing highly permeable and preferential pathways for n -BtOH. Importantly, compared to other reported PDMS-based mixed matrix membranes containing conventional microporous particles, our CTF-incorporated PDMS (CTF/PDMS) membrane exhibited a significantly higher flux and excellent separation factor. Increasing feed temperature...
