Abstract
Described herein are foam-like materials having substantially the same physical structure of polyurethane foams but with properties that can be tailored for a particular application. Methods of forming these foam-like materials are also described.
Claims18
A porous material made by the steps of:
- providing a polyurethane foam base material having a porous surface;
- contacting the base material with a first fluid material;
- drawing the first fluid material into intimate contact with the base material to form a coat of the first fluid material on the base material;
- curing the coat on the base material;
- and
- removing the base material from the cured coat, resulting in a porous material comprising the cured first fluid material.

A porous material made by the steps of:
- providing an open cell polyurethane foam base material having a porous surface;
- contacting the base material with a liquid silicone dispersion to form a coating on the base material;
- removing a portion of the liquid silicone dispersion from the base material by using a vacuum to draw the first fluid material into intimate contact with the porous surface of the base material and using positive air pressure to blow away excess fluid material;
- curing the liquid silicone dispersion remaining on the base material after the step of removing a portion, to form a cured silicone elastomer coating on the base material;
- and
- removing the base material from the silicone elastomer coating, thereby leaving a porous material comprising silicone.
