AB - Biomass‐originated materials are the future's next‐tier polymers. This work suggests improving mechanical and barrier properties of nature‐sourced polymers using non‐covalent supramolecular interactions. Polysaccharide chitosan is modified with amino acids via an esterification pathway using a systematic variation of hydrogen bond and aromatic domains (Degrees of substitution 12–49%). These controlled modifications improve stability due to non‐covalent interactions, resulting in biopolymers with tailored thermal (decomposition temperature 232–275 °C), mechanical (Young's modulus 540–2667 MPa), and surface properties (roughness 4–40 nm). Chitosan and natural amino acids that are already manufactured at scale are purposely selected. The facile synthesis, controlled properties, stimuli‐responsive potential, and inexhaustible origin of the raw materials provide the presented findings with the potential to become the method for the formation of high‐performance biodegradable alternatives to petroleum‐based polymers that can be used in packaging, food, agriculture, and medicine.
