"insufficient energy density/ MXene nanosheet difficulty stablizing 3D printing inks, overcome using layer-by-layer deposition enabling precise microporous hierarchical/ interfacial architecture construction... material design flexibility, process controllability, scalability... DIW 3D printed interdigitated structure encapsulated with H2SO4-PVA solid electrolyte, some HNC as crosslinking agent inhibiting nanosheet agglomeration/ optimizing ink's shear-thinning... flexible electronics, energy storage, smart sensing"
