Phase inversion (chemistry)

Not to be confused with Phase inversion.

Phase inversion (also called phase separation or demixing) refers to two related phenomena in chemistry and materials science: (1) a controlled phase-separation process widely used to fabricate porous polymer membranes, and (2) the inversion of continuous and dispersed phases in an emulsion.

In membrane fabrication, phase inversion converts an initially homogeneous polymer solution into a solid, porous structure by inducing phase separation and solidification.
