| Outline of Final Research Achievements |
Polymer-based membranes are widely used for gas separation, filtration, desalination of seawater, wastewater treatment, etc. Chemical, petrochemical, energy and environment-related industries, however, strongly require highly durable membranes applicable under extreme conditions, since the present polymeric membranes gradually deteriorate with time due to undesired swelling, clogging, and chemical reactions. At present, a widely used technique for diamond-like carbon (DLC) deposition is plasma chemical vapor deposition (CVD) using organic compounds. In the plasma CVD of organic compounds, a highly cross-linked network of sp3 carbons is obtained under certain conditions, resulting in thin carbon films with mechanical stability comparable to that of diamond. Recently, we successfully prepared nanoporous DLC membranes which exhibited extremely high permeability to water and organic solvents while maintaining a considerable degree of mechanical strength.
