Improvements in and relating to material separations

摘要

A method of separating at least part of one or more components from a mixture of components includes exposing the mixture to a porous barrier, the barrier being formed of a material structure having, or behaving in the manner associated with, a negative Poisson ratio. Through the use of such materials, improved reparations, improved de-fouling of barriers and a variety of other beneficial properties can be obtained.
