In this study, ZIF-67/cellulose nanofiber (CNF)-derived Co–C/C aerogel with an integrated design for microwave absorption and thermal camouflage functions was prepared. The hierarchical pore structure with coexisting micron-scale skeletal pores and MOF-derived nanopores was constructed through in-situ growth of ZIF-67 on CNF and low-temperature carbonization regulation. Simultaneously, uniformly distributed Co nanoparticles (20–30 nm) and defect-rich graphitized carbon heterointerfaces were obtained. The Co–C/C aerogel exhibited an ultra-low density (16.21–17.35 mg/cm<sup>3</sup>). In terms of microwave absorption, it achieved an effective absorption bandwidth of 6.87 GHz (covering the Ku band) at a thickness of 2.4 mm. This was attributed to the synergistic mechanisms of multiple scattering from hierarchical pores, enhanced interfacial polarization induced by low-temperature carbonization, and magnetic loss from Co nanoparticles. In addition, the material demonstrated a low thermal conductivity of 0.0492 W m<sup>−1</sup> K<sup>−1</sup>, and infrared imaging revealed its significant thermal signal shielding capability.

However, transforming such dispersions into functional and continuous thin films of graphene remains challenging due to limitations of conventional coating techniques such as spray coating, spin coating, drop casting, Langmuir-Blodgett deposition and printing. These methods often result random orientation and aggregation of nanosheets leading to thicker films and requiring sophisticated processing. Although graphene possesses exceptional physical properties arising from its unique structure, its full potential has yet to be realized, largely due to the absence of efficient and cost-effective thin film preparation methods. In this work, we report a self-assembly approach at the liquid-air interface that utilizes a volatile solvent to guide the dispersed nanosheets from random motion in the liquid phase into an orderly, tiled thin-film. Capillary forces during the drying process, driven by the Marangoni effect, result in the rapid formation of a distinct monolayer at the interface within 2 min as the volatile solvent evaporates. Sub-micron graphene thin films with different aspect ratios, multilayers and controlled film thicknesses in the range of ∼65 nm to ∼1 μm are successfully prepared. These self-assembled graphene films demonstrate an electrical conductivity of ≥ 10<sup>4</sup> S/m and a negative temperature coefficient of resistance of −8 × 10<sup>−4</sup>/°C.

Herein, we developed a strain/humidity bimodal sensor based on a graphene-cellulose nanofibril (graphene-CNF) composite film. The sensor demonstrates superior strain sensing (GF = ∼380 within 0 %–20 % strain) and humidity sensing (0.58 RH<sup>-1</sup> within 5 %–90 % RH) performance, as well as unique moisture-triggered self-healing properties (with a healing efficiency of 47.3 % and healing time of 40 s). The multimodal functionality enables versatile applications spanning skin-attachable physiological sensing, environmental monitoring, and proximity-responsive human-machine interfaces. Specifically for respiratory monitoring, the sensor achieves concurrent acquisition of ventilatory waveforms and the hydration status of the exhaled gas, which facilitates the systemic physiological assessment.
