B01D67/0034 - CPC Classification

Classification description:

Processes specially adapted for manufacturing semi-permeable membranes for separation processes or apparatus; Organic membrane manufacture by inducing porosity into non porous precursor membranes by elimination of segments of the precursor, e.g. nucleation-track membranes, lithography or laser methods by micromachining techniques, e.g. using masking and etching steps, photolithography
