Calibrated Membranes with Coated Pore Walls

Calibrated Membranes with Coated Pore Walls

Extremely uniform small-radius pores, formed in thin mica membranes, have been coated with mono-and multimolecular layers of fatty acids. Stearate monolayers orient themselves on the pore walls in layers 25 to 28 angstroms thick. The resulting membranes, with radii of the order 100 angstroms or less...

Zusammenfassung:Extremely uniform small-radius pores, formed in thin mica membranes, have been coated with mono-and multimolecular layers of fatty acids. Stearate monolayers orient themselves on the pore walls in layers 25 to 28 angstroms thick. The resulting membranes, with radii of the order 100 angstroms or less, may have applications in simulating certain features of biological membranes and in fabricating highly selective membranes for differential dialysis or ultrafiltration.
