Abstract
A degradable containment includes an outer structural layer constructed of a pulp material, a central carrier layer constructed of a biopolymer, and an interior nanomaterial layer constructed of a nanomaterial.
Claims14
A layered containment comprising:
- an outer structural layer defining a containment cavity and constructed of a pulp material;
- an interior nanomaterial layer constructed of at least one of the following:
- silicon dioxide, zinc oxide, and/or a nanomaterial of hydrophobic nanoparticles;
- and,
- a central carrier layer underlying the outer structural layer and constructed of a biopolymer,
- wherein the outer structural layer comprises a plurality of parts adhered by the central carrier layer and/or the interior nanomaterial layer without an additional adhesive and wherein the central carrier layer and/or the interior nanomaterial layer extend from a cavity of the containment to cover a portion or the entire exterior surface of the layered containment;
- and
- wherein the biopolymer comprises polyhydroxyalkanoate, lignin, or a mixture thereof.
