Reticulated foam

In a reticulated foam only the lineal boundaries where the bubbles meet (Plateau borders) remain.

The solid component of a reticulated foam may be an organic polymer like polyurethane, a ceramic, or a metal.

These materials are used in a wide range of applications where the high porosity and large surface area are needed, including filters, catalyst supports, fuel tank inserts, and loudspeaker covers.

While Plateau's laws, the rules governing the shape of soap films in foams were developed in the 19th century, a mathematical description of the structure is still debated.
