Liquid transport member having a high permeability bulk region and a high critical pressure port region

摘要

The present invention is a Liquid transport member with significantly improved liquid handling properties, having at least one bulk region completely circumscribed by a wall region, and which comprises at least one port region, where the product of the bubble point pressure of the port region multiplied with the bulk region permeability is higher than half of the product of the porosity of the member multiplied by the surface tension of the transported liquid.
