Carbon nanolayers designed to absorb carbon dioxide.(EMERGING TECHNOLOGY)(Brief article)

Advanced Materials & Processes, July, 2007

A nanotechnology called electrostatic layer-by-layer self-assembly is under development by scientists from the Dept. of Energy's National Energy Technology Laboratory, the West Virginia University School of Medicine, and the University of Pittsburgh's Chemical Engineering Department. Originally developed for medical applications, the technology shows promise in the development of sorbent technology for the capture of carbon dioxide.

The LBL process involves repeatedly dipping a substrate into an amine solution, each dip creating a layer of approximately one to two nanometers. The process has the potential to produce highly efficient, highly uniform solid sorbents containing perhaps 100 times more of the amines than are deposited by the sorbent-preparation...
