Provided are compositions that include at least one two-dimensional layer of an inorganic compound and at least one layer of an organic compound in the form of one or more polypeptides. Methods of making and using the materials are provided. The organic layer contains one or more polypeptides, each of which have alternating repeats of crystallite-forming subsequences and amorphous subsequences. The crystallite-forming subsequences form crystallites comprising stacks of one or more beta-sheets. The amorphous subsequences form a network of hydrogen bonds. A method includes i) combining one or more polypeptides with an inorganic material and an organic solvent, and ii) depositing one or more polypeptides, the inorganic material and the organic solvent onto a substrate. These steps can be repeated to provide a composite material that is a multilayer composite material. The composite materials can be used in a wide array of textile, electronic, semi-conducting, and other applications.
A method of making a composite material comprising at least one two-dimensional (2D) inorganic layer comprising two-dimensional titanium carbide (MXene) and an at least one organic layer, the organic layer comprising one or more polypeptides which comprise alternating repeats of crystallite-forming subsequences and amorphous subsequences, wherein the crystallite-forming subsequences form crystallites comprising stacks of one or more β-sheets, and wherein the amorphous subsequences form a network of hydrogen bonds, the method comprising i) combining the one or more polypeptides with an inorganic material and an organic solvent, and ii) depositing the one or more polypeptides, the inorganic material and the organic solvent onto a substrate, thereby forming at least one composite layer comprising the one or more polypeptides and the inorganic material, and optionally repeating i) and ii) to form the composite material that is a multilayer composite material.
