Under well-defined conditions two polymers can form continous network structures as shown on this electron micrograph.

[polysulfone]

A scanning electron micrograph of a surface of a polysulfone-membrane of approximately 1.0 um pore size. The membrane can be used for separation of cell material in aqueous protein solutions.
