| Research Abstract |
High performance filtration membranes made of diamond-like carbon (DLC) were developed. DLC membranes obtained by plasma CVD or sputtering techniques showed superior properties as organic-solvent resistant nanofiltration membranes when proper porous alumina or polymeric substrates were used. Organic solvents quickly permeated through a DLC layer with pores less than 1 nm in diameter and the solvent flux increased inversely proportional to the viscosity of the solvents. The hydrophilicity of the nanopores increased when nitrogen atoms were introduced into the DLC layer. Furthermore, by the selection of proper polymeric substrates and controlling the deposition conditions, we could successfully fabricated nanopores no more than 0.8 nm in diameter, which can reject azobenzene perfectly and about 90% of sodium chloride.
