Carbon capture paint compositions and methods of making and using the same to capture carbon dioxide from air

A method of capturing carbon dioxide in a paint composition, comprising:

• providing a paint composition, wherein the paint composition includes from about 25.0 volume percent to about 45.0 volume percent of metal silicate particles, and
• from about 4.0 volume percent to about 8.0 volume percent of a binder, wherein the binder comprises poly(3,4-dihydroxyphenylalanine),
• from about 15.0 volume percent to about 35.0 volume percent of pigment particles, and water,
• based on a total volume of the paint composition;
• forming a paint composition on a surface by applying the paint composition to the surface;
• and
• exposing the paint composition on the surface to ambient air for a carbon capture duration.

A method of manufacturing a paint composition comprising:

• providing water,
• forming a binder solution by adding a binder volume of a binder to the water, and
• forming the paint composition by adding a pigment volume of pigment particles and a silicate volume of metal silicate particles to the binder solution,
• wherein the paint composition includes from about 25.0 volume percent to about 45.0 volume percent of the metal silicate particles,
• from about 4.0 volume percent to about 8.0 volume percent of the binder, wherein the binder comprises poly(3,4-dihydroxyphenylalanine),
• from about 15.0 volume percent to about 35.0 volume percent of the pigment particles, and a water volume of water.
