A Simple and Effective Method for the Preparation of Porous Membranes with Three‐Dimensionally Arranged Pores

Abstract

A one‐step process for the preparation of porous polymer membranes (see Figure) by spreading mixtures of particles and organic liquid onto a water surface, followed by solidification of the liquid, removal of the particles, and transfer to desired supports, is reported (see Figure). The thickness of the porous membranes can be tuned from a single layer to more than ten layers.
