Mixed matrix membranes prepared from high impact polystyrene with dispersed TiO2 nanoparticles for gas separation
The current study presents synthesis and characterization of high impact polystyrene - TiO2 nanoparticles mixed matrix membranes for separation of carbon dioxide from nitrogen. The solution-casting method was used for preparation of membranes. The nano mixed matrix membranes were characterized using scanning electron microscopy to ensure the suitable dispersion of nano particles in high impact ...
متن کاملGas Separation Properties of Mixed Matrix Membranes based on Polyimide and Graphite Oxide
In this work, three different graphene-based materials, namely graphite oxide (GrO), thermally reduced graphite oxide (T-RGrO) and ascorbic acid multi-phase reduced graphene oxide (AMP-RGO), were synthesized and used to produce mixed matrix membranes (MMM) based on Matrimid®5218 for as separation. From the samples produced, a complete set of characterization was performed including XRD, FTIR, T...
متن کاملCorrelation of separation factor versus permeability for polymeric membranes
The separation of gases utlhzmg polymenc membranes has emerged mto a commercially utlhzed unit operation It has been recogmzed m the past decade that the separation factor for gas pairs vanes inversely with the permeablhty of the more permeable gas of the speclflc pair An analysis of the literature data for bmary gas mixtures from the hst of He, Hz, 02, Nz, CH4, and COz reveals an upper bound r...

متن کاملCryogenic Permeability of Polyimide Shells
Polyimide shells are used as targets in Inertial Confinement Fusion (ICF) experiments. These shells are filled with DT gas, then cooled to low temperatures for cryogenic laser shots. During target preparation, shells require careful pressure and temperature control due to their sensitivity. The pressure is governed partly by permeation through the shell wall, which can only be determined with t...
