High-performance asymmetric isoporous nanocomposite membranes with chemically-tailored amphiphilic nanochannels

Amphiphilic Membranes

Amphiphilic molecules (the word derives from the Greek αμφὶ φιλία, meaning “love on both sides”) are molecules which both love and hate water. They are formed by two parts with very different tastes, which are covalently bound together: one, the hydrophilic head, is polar or even ionized, and tends therefore to be close to the small, polar water molecules; the other, the hydrophobic tail, is us...

Polysulfone/ Carbon Nanotubes Asymmetric Nanocomposite Membranes: Effect of Nanotubes Surface Modification on Morphology and Water Permeability

Polysulfone/carbon nanotubes (PSF/CNTs) nanocomposite membrane was prepared via phase inversion induced by immersion precipitation technique. In addition, the surface of the CNTs were functionalized by polar carboxylic and amine groups to improve the interaction between the CNTs and the polymer matrix. For this purpose, the neat CNTs were chemically treated using sulfuric acid/ nitric acid (H2S...

Green Synthesis Nanocomposite Membranes

High-performance multi-functional reverse osmosis membranes obtained by carbon nanotube·polyamide nanocomposite

Clean water obtained by desalinating sea water or by purifying wastewater, constitutes a major technological objective in the so-called water century. In this work, a high-performance reverse osmosis (RO) composite thin membrane using multi-walled carbon nanotubes (MWCNT) and aromatic polyamide (PA), was successfully prepared by interfacial polymerization. The effect of MWCNT on the chlorine re...

Nanocomposite Electrodes for High-Performance Supercapacitors

S are a unique type of high-power electrochemical energy storage devices being developed for a wide range of applications, including consumer electronics, medical electronics, electrical utilities, transportation, and military defense systems. However, the energy and power densities, safety, and cycle life of currently available supercapacitors need to be significantly improved to satisfy the r...
