Aqueous foam compositions and methods

A method of preparing a fire suppressing aqueous foam composition, comprising:

• combining water, a surfactant, and a carbon element to thereby generate an aeratable slurry;
• wherein
• the carbon element consists of at least one or more of graphene, graphene oxide, and graphite oxide;
• the surfactant is a non-fluorinated surfactant;
• and
• the aqueous foam composition is non-fluorinated.

A fire suppressing aqueous foam composition, comprising:

• water;
• a surfactant;
• a carbon element;
• a water-soluble polymer;
• a solvent;
• a corrosion inhibitor;
• a biocide;
• wherein
• the surfactant
• is a non-fluorinated surfactant;
• is present at 2-25 wt %;
• comprises one or more of an anionic surfactant, a cationic surfactant, a zwitterionic surfactant, and a nonionic surfactant;
• the carbon element
• consists of at least one or more of graphene, graphene oxide, and graphite oxide;
• is present at about 0.1-10 wt %;
• the water-soluble polymer is present at 0.0-3 wt %;
• the solvent
• is present at 3-20 wt %;
• comprises one or more of a glycol and a glycol ether;
• the corrosion inhibitor is present at 0.002-1 wt %;
• and
• the aqueous foam composition is non-fluorinated.
