Anisotropic porous material

摘要

The present invention is to provide an anisotropic porous material for a fluid filter which can perform a separation process of a large amount of fluid with high accuracy, which can achieve high flux, and which can improve detergent properties. The anisotropic porous material includes a plurality of pores. Each of the pores has an anisotropic shape in which a major axis and a minor axis can be defined. An arrangement of the pores has an orientation.
