Plastics play an indispensable role in daily life, but their adverse impacts on nature and human health are becoming increasingly severe due to their non-degradability and the persistent accumulation of plastic waste. It is essential to develop biodegradable, sustainable alternatives with favorable mechanical properties. Here, we developed a dilute-solution-based strategy that enables the facile and scalable production of high strength sustainable nanocomposites with multicomponent synergistic reinforcement. Owing to the shear-flow-induced nanosheets alignment and strong interfacial interactions, the nanocomposites achieve outstanding mechanical properties, with a high tensile strength of 566.9 ± 13.5 MPa. Moreover, these nanocomposites possess electromechanical stability and thermal stability, and can fully biodegrade within 30 days in natural soil. This strategy provides an effective pathway for the design of high-performance sustainable nanocomposites.
