Shear-flow-induced Assembly Of 2D Nanosheets For The Fabrication Of Composite Films With High Tensile Strength – Nature

Nature Aug 28, 2026

High-performance bioinspired composite materials require the precise alignment of synthetic nanosheets to mimic the mechanical properties of highly ordered laminated microstructures found in nature. Here we detail a nanosheet superspreading alignment strategy for fabricating nanocomposite films that uses shear-flow forces at the interface between two immiscible phases to induce long-range high-order alignment of the 2D nanosheets that enhances the films8217 mechanical properties. In situ interface crystallization or cross-linking follows the alignment and effectively locks the oriented configuration the resulting orientation order parameter is ampgt0.85. Subsequent solvent dewetting enables continuous film formation over large areas while maintaining well-defined microstructural integrity. This process overcomes the misorientation and aggregation typical of conventional alignment methods and can be scaled using a multi-nozzle extrusion setup compatible with commercial heating and film-collection components. The step-by-step procedures cover the nanosheet precursor preparation the continuous-film fabrication and their microstructural characterization and require 880423 days to complete. The procedures are applicable to a broad range of nanosheet materials including graphene oxide MXenes transition-metal dichalcogenides and layered clays and the resulting composite films exhibit enhanced mechanical strength toughness and multifunctionality. Nanocomposites based on graphene oxide and clay nanosheets exhibit a tensile strength of up to 1215 177 80 MPa mean 177 s.d and a Young8217s modulus of 198.8 177 6.5 GPa while clay-based nanocomposite films reach a toughness of 36.7 177 3.0 MJ m87223. Superspreading alignment is a versatile and robust approach for the scalable fabrication of high-performance composites for materials science. We present a protocol for the fabrication of highly ordered composite films in which 2D nanosheets can be aligned and fixed yielding high tensile strength and suitability for high-performance wearable electronics.
