Preparation and characterization of SPEEK/MMT-STA composite membrane for DMFC application
A silicotungstic acid (STA) was successfully impregnated onto K10 montmorillonite (MMT) in an effort to improve the properties of SPEEK membrane. Several characterizations such as Fourier transform infrared (FTIR), X-ray diffraction (XRD) and field emission scanning electron microscopy (FESEM) were carried out in order to confirm the entrapment of STA molecule onto MMT. It was found that the ST...
متن کاملStudies on the SPEEK membrane with low degree of sulfonation as a stable proton exchange membrane for fuel cell applications
Sulfonated poly (ether ether ketone) (SPEEK) with a low degree of sulfonation (DS = 40%) was prepared for proton exchange membrane fuel cells (PEMFC). Poly (ether ether ketone) (PEEK) was sulfonated in concentrated H2SO4 under N2 atmosphere and characterized by the hydrogen nuclear magnetic resonance (H-NMR) technique. After preparation of the SPEEK polymer, the obtained polymer was dissolved i...
متن کاملA Novel Composite Membrane for pH Responsive Permeation
Objective(s) In this study, a kind of pH sensitive composite membrane was prepared and drug permeation through it was investigated in terms of pH. Rationale of this study originated from the fact that a pH change which may be a result of a disease state in the body can trigger drug release. Materials and Methods Here, a kind of pH sensitive composite membrane containing different nanoparticle ...
متن کاملZwitterion Embedded Thin Film Composite Membrane for Oily Wastewater Treatment
The recent development in oil and gas industry increases the production and consumption of oil. The enormous amount of oily wastewater produced is urged to be treated to prevent humanity and environment from being threatened. Membrane technology is an appealing alternative for oily wastewater treatment due to its design simplicity, energy efficiency and environmentally benign approach. In this ...
متن کاملChitosan/Polyethersulfone Composite Nanofiltration Membrane for Industrial Wastewater Treatment
Chitosan/polyethersulfone (CS/PES) composite membrane was prepared from casting chitosan solution on polyethersulfone substrate membrane. The Substrate membrane was prepared by phase inversion technique using polyethersulfone (PES) and dimethylacetamide (DMAc) as solvent with and without the addition of polyvinylpyrrolidone (PVP) as pore-forming agent. The effects of the composition of the c...
