“…Screening the polymer matrices and fillers can provide high-performance gas separation MMMs by increasing their compatibility. − Polymer matrices include glassy polymers (6FDA-DAM, PSF), , rubber polymers (PU, PVAC), , cellulose polymers (EC, AC), , and new-type polymers (PIMs). , The −CF 3 groups of 6FDA-type polyimide polymers show properties of rigidity, medium permeability, and good olefin/alkane selectivity, making 6FDA-type polyimide polymers a promising polymer matrix. Ethylcellulose (EC), with a large free volume and a low glass transition temperature, shows a potential application in olefin/paraffin separation.…”

The development of efficient membranes for ethylene/ethane (C 2 H 4 /C 2 H 6 ) separation is highly important. Here, we report the development of a series of new mixed matrix membranes (ZnAtzPO 4 /6FDA-DAM MMMs) based on a microporous material with phosphate anion pillar ZnAtzPO 4 (Atz = 3-amino-1, 2, 4-triazole) and 6FDA-DAM polymer matrix. Compared with the pure 6FDA-DAM membranes, the C 2 H 4 permeability and the C 2 H 4 /C 2 H 6 selectivity of 10 wt % ZnAtzPO 4 /6FDA-DAM MMMs were simultaneously increased by 46 and 6%, breaking the trade-off between permeability and selectivity. Interestingly, the separation performance of ZnAtzPO 4 /6FDA-DAM MMMs at 10 wt % for the equimolar C 2 H 4 /C 2 H 6 gas mixture was 105.0 Barrer and 3.90, which surpassed the 2013 upper bound of C 2 H 4 /C 2 H 6 . For ZnAtzPO 4 /6FDA-DAM MMMs with 10 wt % filler loading, both the solubility selectivity and the diffusion selectivity continued to rise concurrently, enhancing the C 2 H 4 /C 2 H 6 separation performance of ZnAtzPO 4 /6FDA-DAM MMMs. This work generates a useful concept for the design and fabrication of highperformance MMMs.

Driven by environmental and economic considerations, this study explores the viability of utilizing coconut juice residues (CJRs), a byproduct from coconut milk production, as a carbon source for bacterial cellulose (BC) synthesis in the form of a versatile bio-membrane. This work investigates the use of optimization modeling as a tool to find the optimal conditions for BC cultivation in consideration of waste minimization and resource sustainability. Optimization efforts focused on three parameters, including pH (4–6), cultivation temperature (20–30 °C), and time (6–10 days) using Design Expert (DE) V.13. The maximum yield of 9.31% (g/g) was achieved when the cultivation took place at the optimal conditions (pH 6, 30 °C, and 8 days). This approach aligns with circular economy principles, contributing to sustainable resource management and environmental impact reduction. The experimental and predicted optimal conditions from DE V.13 were in good agreement, validating the study’s outcomes. The predictive model gave the correlations of the optimal conditions in response to the highest yield and maximum eco-efficiency. The use of prediction modeling resulted in a useful tool for forecasting and obtaining guidelines that can assist other researchers in calculating optimal conditions for a desired yield. Acetylation of the BC resulted in cellulose acetate (CA) membranes. The CA membrane exhibited the potential to separate CO2 from a CH4/CO2 mixed gas with a CO2 selectivity of 1.315 in a membrane separation. The promising gas separation results could be further explored to be utilized in biogas purification applications.
