Abstract: This disclosure relates to collagen like polypeptides, applications, and uses related thereto. In certain embodiments, the disclosure relates to collagen like polypeptides wherein hydroxy proline is substituted with amino proline and containing amino acids having side chains with carboxylic acids wherein the polypeptides are configured through electrostatic interactions of the amine and carboxylic acid groups to form solid structures. In certain embodiments, the disclosure contemplates modifications of these polypeptides in order to impart desirable properties to the solid structures.

Abstract: Synthetic protein copolymers with plastic and elastic properties, and methods producing the copolymers, are provided. For example, a BAB triblock copolymer comprises a hydrophilic block and one or more hydrophobic blocks. The mechanical properties of a gel, fiber, fiber network, or film form of the copolymer are varied by one or more conditions before or after copolymer production. For example, a copolymer sequence can be varied before production, and one or more processing conditions such as solvent, pH, or temperature can be varied after production.
