Recent developments in carbon nanotube membranes for water purification and gas separation
journal contribution
posted on 2010-01-01, 00:00 authored by K Sears, Ludovic Dumee, J Schütz, Fenghua She, C Huynh, S Hawkins, M Duke, S GrayCarbon nanotubes (CNTs) are nanoscale cylinders of graphene with exceptional properties such as high mechanical strength, high aspect ratio and large specific surface area. To exploit these properties for membranes, macroscopic structures need to be designed with controlled porosity and pore size. This manuscript reviews recent progress on two such structures: (i) CNT Bucky-papers, a non-woven, paper like structure of randomly entangled CNTs, and (ii) isoporous CNT membranes, where the hollow CNT interior acts as a membrane pore. The construction of these two types of membranes will be discussed, characterization and permeance results compared, and some promising applications presented.
