Summary: In this study, nanocomposite membranes with uniform dispersion of amorphous PANI nanofibers were prepared using different concentrations of Pebax 1657 and PANI. The membranes exhibited defect-free structures and lower crystallinities. As the nanofiber loading increased, the CO2 permeability and selectivity of the membranes increased, surpassing the Robeson upper bound limit and approaching the values in 2008. The CO2 permeability and ideal CO2/CH4 selectivity of the nanocomposite membrane loaded with 10 wt.% PANI nanofibers increased to 121.2 Barrer and 33, respectively, showing increments of 64% and 40%.

Summary: Membrane bioreactors (MBRs) have gained attention in recent years as biotechnology-based wastewater treatment processes. However, the issue of membrane fouling/biofouling has limited their widespread use. A novel MIL-101(Cr) (MCPs)/polyethersulfone (PES) composite membrane was prepared using the phase inversion method. Adding 0.4 wt% MCPs significantly improved the hydrophilicity and pore characteristics of the membrane, resulting in reduced fouling/biofouling. The optimal composite membrane exhibited improved water flux, fouling resistance, and COD removal efficiency.

Summary: For the first time, lycopodium was incorporated into a polyvinylidene fluoride matrix to fabricate a lycopodium/polyvinylidene fluoride membrane for desalination applications. The membrane showed superior performance in terms of flux, salt rejection, water contact angle, and hydrophobicity compared to the neat polyvinylidene fluoride membrane. The presence of lycopodium with its hydrophobic nature and interconnected nano-channels in the membrane structure contributed to the improved flux and salt rejection.
