Pregnant women are often faced with electromagnetic pollution, edema, joint pain, mobility difficulties, and abnormalities in the heart rate. Designing targeted multifunctional intelligent wearable devices to shield against electromagnetic radiation hazards, relieve edema and joint pain, monitor movement and pulse is urgent. Herein, an unprecedented strategy is proposed to combine a metal–organic framework and a fabric substrate for electromagnetic interference shielding. Co@C@carbon fabric (Co-CCF) derived from ZIF-67@cotton fabric was prepared by simple in situ growth and annealing. Subsequently, the Co-PCCF was prepared by encapsulating Co-CCF using polydimethylsiloxane, which improves corrosion resistance and adhesive strength. Co-PCCF-1000 (annealing at 1000 °C) with a double conductive network structure shows efficient electromagnetic shielding performance (blocks more than 99.9% of electromagnetic waves). Co-PCCF with flexibility also shows fantastic fastness and stability to avoid damages during their use by pregnant women (still blocks more than 99% of electromagnetic waves after being repeatedly bent for 500 cycles at 90° and undergoing the ultrasonic treatment for 1 h and 1 M acid/salt/alkali corrosion for 12 h, respectively). In addition, Co-PCCF can reach the required thermal therapy temperature by controlling the voltage (1.5–3 V corresponding to 41.8–84.9 °C) and illumination intensity (0.2 W/cm2 corresponding to 70.8 °C). Meanwhile, Co-PCCF can monitor a wide range of human movement in real time, such as pulse, breath, and joint activities. Multifunctional Co-PCCF designed for pregnant women can effectively prevent electromagnetic pollution, relieve joint pain, and detect the human movement and possesses wide application prospects.

With the rapid development of information technology, the application scenarios of electromagnetic interference (EMI) shielding materials are more diversified. It is difficult for traditional EMI shielding materials to possess low density, high EMI shielding performance, strength, and flexibility in extreme environments such as oxidation/deformation/salt/alkali/high temperature/impact energy/bacteria. Herein, reduced graphene oxide nanosheets (RGO) and Ni nanoparticles were subsequently coated on glass fabrics (GFs) modified with bovine serum albumin (BSA) by adhesion, electrostatic adsorption, and metallization. A 1D glass fiber modified with BSA was used as a flexible substrate, while 2D RGO nanosheets that adhered on the surface of the abovementioned fibers provide a large specific surface area and structural defects and further promote the anchoring of 0D Ni nanoparticles. 2D/1D/0D construction shows an excellent synergistic effect, which promotes the formation of a firm conductive network and lays the foundation for multifunction. EMI shielding efficiency (EMI SE) of the prepared BSA/RGO/Ni-GFs (BRNGs) ranges from 52 to 72 dB in the range of 2−18 GHz. 2D/1D/0D BRNGs with flexibility also show fantastic binding fastness (EMI SE maintaining 89.1 and 86.0% after repeated bending 400 cycles at 90°and ultrasonic damage for 1 h, respectively) and chemical stability (EMI SE remaining 80.2, 95.3, and 92.6% after 200 °C oxidation for 12 h and salt/alkali corrosion for 12 h). In addition, Joule heating, photothermal properties, contact angle, heat dissipation, and mechanical and antibacterial properties of BRNGs were tested. The integration of excellent energy conversion, heat dissipation, and mechanical strength further improves the practicability of the electromagnetic shielding material. Antibacterial and hydrophobic properties of BRNGs are also beneficial to prolong the service life. This study provides a new idea for the design of multifunctional electromagnetic shielding composites.
