Process and apparatus for producing a molecularly oriented film

摘要

Apparatus for forming a film of uniformly oriented molecules from a solution or suspension of the molecules including means to house the molecules in a swinging bucket centrifugation apparatus. The housing means has a gravitational isopotential surface with a radius of curvature equal to the distance between the surface and the spin axis of the centrifugation apparatus. The isopotential surface is normal to the direction of the gravitational forces during spinning. Means for evaporating solvent during centrifugation is provided.
