3D-shaped 3D-continuously graphene cellulose(3D^(2)GC)architecture

In the endeavor to develop three-dimensional(3D)-architected sophisticated hierarchical structures,the synergy between inplane and out-of-plane interactions at interfaces offers new functionalities.This interplay,governed by van der Waals(vdW)interfacial nanoarchitectonics,facilitates the design of efficient thermally conductive pathways.This work delves into the kinetics underlying a dual-templating strategy,seamlessly integrating two-dimensional(2D)-graphene sheets with one-dimensional(1D)-cellulose chains at heterointerfaces,thereby transforming into 3D-shaped and 3D-continuously anisotropic structures,termed as(3D^(2)GC)architecture.Hereby,we designed and fabricated an anisotropic graphene cellulose scaffold(GCS)employing a nickel template.The as-grown GCS replicates the 3D-shaped and configuration of the template.The 3D-continuously interconnected fibrous-porous network of the GCS,combined with its anisotropic thermal properties(λ_(axial)/λ_(radial)),not only is promising for advanced thermal technologies but also offers advantages in cost-effectiveness and eco-effectiveness.
