Abstract
Protein polyurethane alloys including one or more proteins dissolved within one or more polyurethanes. The protein polyurethane alloy may have one or more mechanical properties that are superior to the polyurethane in the absence of protein. The protein polyurethane alloys may be incorporated into a layered material including one or more protein polyurethane alloy layers.
Claims14
An aqueous protein polyurethane alloy formulation, comprising:
- water;
- a polyurethane;
- a protein dissolved within at least the polyurethane;
- and
- a foam stabilizer selected from the group consisting of:
- a nonionic surfactant, an anionic surfactant, a hydrophobically-modified ethylene oxide urethane, and a non-ionic silicone dispersion,
- wherein the formulation comprises about 5 wt % to about 60 wt % of the protein and about 10 wt % to about 85 wt % of the polyurethane, based on the weight of protein and polyurethane.
