• Defect-free ZIF-8/GO/PIM-1 thin-film nanocomposite (TFN) membranes were fabricated. 2D ZIF/GO was produced by in situ growth of ZIF-8 on GO sheets as a continuous, uniform and thin layer. ZIF-8/GO composite results high dispersity compatibility ZG within PIM-1. PIM-1 infiltration into PVDF substrate avoided water pre-impregnation. TFN display PSI (228 kg m −2 h −1 ). In this work, film super-...

SILICONE1200 is an inexpensive domestic poly (dimethylsiloxane)-based sealer that was used in this study to remove volatile organic compounds from over-saturated water using the pervaporation technique. A series of liquid representing important part polluting products released every day were chosen for study. These alkyl halides (chloroform), aromatics (toluene), aliphatic hydrocarbons (heptane...

We study the influence of variations cross-section on drying dynamics by pervaporation in microfluidic channels surrounded water-permeable polydimethylsiloxane (PDMS) walls. Single linearly increasing and decreasing width display similar time, but different towards final drying. with stepwise or show jumps velocity when meniscus separating water-filled dry part channel crosses steps. In branche...

Facilitated transport membranes of polydimethylsiloxane (PDMS) with silver oxide (Ag2O) as the carrier were prepared and used for the separation of thiophenes/n-octane mixtures. The effect of the degree of Ag2O loading, feed temperature on the pervaporation properties of Ag2O-filled membranes was investigated experimentally. Ag2O-filling leads to an increase in selectivity to thiophenes but a d...

As a well-known one-atom thick nanosheets with preeminent physicochemical properties, graphene and its derivatives (e.g., graphene oxide, GO) have shown great potential on the membrane separation filed. This paper presents an update of GO laminates developments, including the membrane preparation methods, physicochemical properties and water vapor transport of GO laminates, and their applicatio...
