Gel foam

It is worth noting that gels, foams and emulsions are all examples of different kinds of solutions. In true solutions the two phases completely mix together but in these systems the two phases are separate. 

A foam that, in addition to the stabilizing surfactants, contains polymer. Polymer thickened foams are formulated to produce increased stability and viscosity. See also Gel Foam, Stiff Foam. 

Protein-polysaccharide cross-linking gives rise to protein conjugates with modified properties, such as an enhanced stability to heat, organic solvents, and proteolysis, which could bear biotechnological applications, but could also be used for preparation of gels, foams, and colloids. 

Modem spermicides are produced in a variety of formulations, including gels, foams, creams, suppositories, pessaries, capsules, foaming tablets, and melting films. Spermicides are also used in conjunction with other methods, such as diaphragms, condoms, and sponges, but also with intrauterine contraceptive devices and methods based on fertility awareness (1).

The liquidity of pure gel is bad, and the flow rate and diffusion range is small. Gel foam can be transported smoothly higher and farther range after adding gel into gas phase medium. 

Gel foam has good sealing performance. When the foam is broken, the gel in the foam continues to play a role of sealing and covering, and ensure the constancy and validity of seahng. 

Gel foam expansion ratio is high, making the gel foam cost of unit volume greatly decreased.
