Stretchable electromagnetic interference (EMI) shields with strain-insensitive EMI shielding and Joule heating performances are highly desirable to be integrated wearable electronics. To explore the possibility of applying geometric design in elastomeric liquid metal (LM) composites fully investigate influence LM geometry on stretchable heating, multifunctional wrinkle-structured LM/Ecoflex sandwich films excellent stretchability developed. The denser wrinkle enables not only better electrical conduction, higher effectiveness (SE) steady-state temperature, but also enhanced strain-stable far-field/near-field performance Joule-heating capability. More strikingly, compared most previously reported or electric heaters, densely wrinkled film could achieve multidirectional behavior slightly strain-enhanced strain-invariant SE under stretching parallel perpendicular field EM waves, as well show ideal over a larger strain range 250%. current findings suggest an effective strategy for developing LM-based properties.

Abstract The incompatibility between low and high frequencies, the constraints of thickness absorption bandwidth, are great challenges for electromagnetic wave (EMW) absorbers. combination microscopic wrinkled morphology macroscopic stacking structure offers possibility constructing lightweight broadband EMW‐absorbing materials. Herein an artificial periodic unit is demonstrated, wCNT@PS/R, which consists urchin‐inspired wrinkled‐carbon nanotube (CNT)‐coated polystyrene (PS) spheres organosilicon rubber matrix. geometry studied optimized. Due to good impedance matching, excellent macrostructural reflections, strong dielectric loss, pentagon achieves a promising effect band (EAB) 12.61 GHz, covering both low‐frequency (S‐ C‐band) high‐frequency (X‐ Ku‐band) bands. 4.0 mm total density as 0.194 g cm −3 , provides new idea cost‐effective preparation thin, ultralight, EMW

The disordered assembly and low conductivity of carbon nanotubes are the main problems that limit application electromagnetic interference (EMI) shielding. In this work, an ordered lamellar structure multiwalled nanotube/Ti3C2Tx (MWCNT/Ti3C2Tx) hybrid films was achieved by vacuum-assisted filtration through hybridization Ti3C2Tx nanosheets nanotubes, where were tightly sticking on surface via physical adsorption hydrogen bonding. Compared with pure films, MWCNT/Ti3C2Tx a significant improvement in 452.5 S/cm EMI shielding effectiveness (SE) 44.3 dB under 50 wt% thickness (8.6 μm) orderly stacking structure, which finally resulted high specific SE (SSE/t, divided density thickness) 55,603.1 dB∙cm2∙g−1.
