Hybrid Microcrystalline Cellulose-Polyvinylidene Fluoride Membrane for Simultaneous Carbon Dioxide Adsorption and Hydration
The alarming high atmospheric carbon dioxide (CO2) concentrations necessitate the development of effective, low-energy, and eco-friendly CO2 capture technologies. Polymeric membrane reactors are promising for gas separation due to their ease of fabrication and low energy requirements. However, they...

The alarming high atmospheric carbon dioxide (CO2) concentrations necessitate the development of effective, low-energy, and eco-friendly CO2 capture technologies. Polymeric membrane reactors are promising for gas separation due to their ease of fabrication and low energy requirements. However, they often suffer from low mechanical strength, thermal stability, permeability, and selectivity. Mixed matrix membranes (MMMs), which combine polymer matrices with inorganic or organic fillers, address these issues. In this study, MMM was fabricated by incorporating microcrystalline cellulose (MCC) with the polyvinylidene fluoride (PVDF) using non-solvent induced phase separation (NIPS) method. Scanning electron microscopy (SEM) revealed that the membranes have elongated finger-like pores and increases in size with higher MCC content. MMM3 (contain 5.0 wt.% MCC) had the highest porosity and mean pore radius of 55.74 % and 19.05 nm respectively. FTIR and XRD confirmed amorphous structure, and also showing the presence of the MCC and PVDF functional groups.
