Fabrication of hybrid polymer/metal organic framework membranes: mixed matrix membranes versus in situ growth
, Journal of Materials Chemistry A, Vol: 2, Pages: 9260-9271, ISSN: 2050-7488Hybrid polymer/metal organic framework (MOF) membranes have been prepared using either a mixed matrix membrane (MMM) or in situ growth (ISG) approach and were evaluated for application in organic solvent nanofiltration (OSN). MMMs were produced by dispersing pre-formed particles of the MOF HKUST-1 in polyimide P84 dope solutions. MMMs demonstrated both (i) higher rejections of styrene oligomers and (ii) lower flux decline than the polymeric control membranes. Furthermore, an alternative hybrid membrane fabrication methodology – in situ growth (ISG) of HKUST-1 in integrally skinned asymmetric polymer membrane supports – has been successfully demonstrated. Ultrafiltration support membranes were submerged in HKUST-1 precursor solutions in order to promote the growth of MOF within the porous structure of the polymer membranes. The presence of HKUST-1 in the membranes was proven with X-ray powder diffraction (XRPD). Energy-dispersive X-ray spectroscopy (EDX) was used to reveal the distribution of HKUST-1 throughout the ISG membranes, and was found to be even across the surface and throughout the cross-section. The ISG membranes also had higher solute rejections and lower flux decline than the MMMs.

Ultrathin Polymer Films with Intrinsic Microporosity: Anomalous Solvent Permeation and High Flux Membranes
, Advanced Functional Materials, Vol: 24, Pages: 4729-4737, ISSN: 1616-3028Organic solvent nanofiltration (OSN) membranes with ultrathin separation layers down to 35 nm in thickness fabricated from a polymer of intrinsic microporosity (PIM-1) are presented. These membranes exhibit exceptionally fast permeation of n-heptane with a rejection for hexaphenylbenzene of about 90%. A 35 nm thick PIM-1 membrane possesses a Young's modulus of 222 MPa, and shows excellent stability under hydraulic pressures of up to 15 bar in OSN. A maximum permeance for n-heptane of 18 Lm−2h−1bar−1 is achieved with a 140 nm thick membrane, which is about two orders of magnitude higher than Starmem240 (a commercial polyimide-based OSN membrane). Unexpectedly, decreasing the film thickness below 140 nm results in an anomalous decrease in permeance, which appears to be related to a packing enhancement of PIM-1, as measured by light interferometry. Further, thermal annealing of the membranes formed from PIM-1 reveals that their permeance is preserved up to temperatures in excess of 150 °C, whereas the permeance of conventional, integrally skinned, asymmetric polyimide OSN membranes decreases significantly when they are annealed under the same conditions. To rationalize this key difference in response of functional performance to annealing, the concept of membranes with intrinsic microporosity (MIMs) versus membranes with extrinsic microporosity (MEMs) is introduced.
