Abstract The recent advancement in mechanically and chemically robust membranes has led to the capabilities of both reverse osmosis (RO) pervaporation (PV) for separation water/organic solvent organic mixtures. However, their performances are evaluated different permeation formulas. To address this, we have conducted an analysis using a unified parameter: activity‐based permeance. present study RO PV same organosilica membrane non‐aqueous solvents (methanol/ethanol, methanol/iso‐propanol [IPA], methanol/dimethyl carbonate) solvent‐aqueous mixtures (including water with methanol, ethanol, IPA, tert‐butanol, glucose), at concentrations ranging from 0% 100%. With use permeance, achieved consistent evaluation processes. Moreover, this approach provides prediction performance even PV.

Hygroscopic materials based on highly hygroscopic salts are promising for atmospheric water harvesting (AWH), but the metal- or halide-containing often have leakage and corrosion issues. Here, design synthesis of halide-free, hygroscopic, macroporous polymers from [2-(acryloyloxy)ethyl]trimethylammonium chloride simply via in situ foaming, solidification, ion exchange reported. The resulting exhibit interconnected structure, robust compression, leakage-free performance, they also demonstrate relatively high moisture adsorption capacities (up to 1.24 g

Abstract An imidazolium‐type room‐temperature ionic liquid containing silsesquioxane frameworks is successfully prepared. The polar products are grafted onto the surface of prepared aromatic polyamide (PA) membranes to improve water flux PA membranes. Membranes with an exhibit a 1.89 L m −2 h −1 bar ), 48% higher than that pure while salt rejection still remains at 96%. This improvement can be attributed enhanced hydrophilicity membrane surface, as evidenced by reduced contact angle.
