A Novel Architecture for Carbon Nanotube Membranes towards Fast and Efficient Oil/water Separation

Abstract Carbon nanotubes (CNT) are robust and proven as promising building blocks for oil/water separating membranes. However, according to classic fluid dynamic theory, achieving high permeation flux without sacrificing other membrane properties is a formidable challenge for CNT membranes, because...
