Abstract Constructing advanced functional nanomaterials with pre‐designed organized morphologies from low‐dimension synthetic and biological components is challenging. Herein, we report an efficient universal amphiphilicity‐driven assembly strategy to construct “hairy” flexible hybrid nanosheets a 1D cellulose nanofibers (CNFs) net conformally wrapped around 2D graphene oxide (GO) monolayers. This interface‐driven bio‐synthetic facilitated by tailoring the surface chemistry of GO sheets, resulting in individual sheets tightly surrounded dense conformal nanocellulose network. The mechanical stability products far exceeds compressive instability limits both components. Additionally, CNF network significantly enhances wetting ability initial hydrophobic reduced nanosheets, allowing fast water transport combined high filtration efficiency.
