Abstract
The invention is directed to a method for producing a composite material comprising a biofabricated material and a secondary component. The secondary component may be a porous material, such as a sheet of paper, cellulose, or fabric that has been coated or otherwise contacted with the biofabricated material. The biofabricated material comprises a uniform network of crosslinked collagen fibrils and provides strength, elasticity and an aesthetic appearance to the composite material.
Claims15
A method for making a composite material comprising:
- dispersing, encapsulating, incorporating, depositing, or otherwise introducing at least one biofabricated material into or onto at least one porous, permeable, or absorptive secondary component;
- wherein the at least one biofabricated material comprises a network of non-human collagen fibrils, wherein less than 10% by weight of the collagen fibrils in the material are in the form of collagen fibers having a diameter of 5 μm or more and less than 10% by weight of the collagen fibrils are in the form of fibrils aligned for 100 μm or more of their lengths;
- wherein said material contains no more than 40% by weight water;
- and wherein said material contains at least 1% of a lubricant;
- or
- dispersing, encapsulating, incorporating, depositing, or otherwise introducing at least one biofabricated material into or onto at least one porous, permeable, or absorptive secondary component;
- wherein said and at least one biofabricated material comprises a network of recombinant non-human collagen fibrils, wherein the collagen contains substantially no hydroxylysine;
- wherein said material contains no more than 25% by weight water;
- and wherein said material contains at least 1% of a lubricant, wherein said lubricant is a fat, castor oil, pine oil, lanolin, mink oil, neatsfoot oil, fish oil, shea butter, aloe, cod oil, a sulfonated oil, a polymer, an organofunctional siloxane, an anionic surfactant, a cationic surfactant, a cationic polymeric surfactant, an anionic polymeric surfactant, an amphiphilic polymer, a fatty acid, a modified fatty acid, a nonionic hydrophilic polymer, a nonionic hydrophobic polymer, a polyacrylic acids, a polymethacrylic acid, an acrylic, a natural rubber, a synthetic rubber, a resin, an amphiphilic anionic polymer, an amphiphilic anionic copolymer, amphiphilic cationic polymer, amphiphilic cationic copolymer, and mixtures thereof.
