The creation of superelastic, flexible three-dimensional (3D) graphene-based architectures is still a great challenge due to structure collapse or significant plastic deformation. Herein, we report facile approach transforming the mechanically fragile reduced graphene oxide (rGO) aerogel into superflexible 3D by introducing water-soluble polyimide (PI). rGO/PI nanocomposites are fabricated using strategies freeze casting and thermal annealing. resulting monoliths exhibit low density,...
The creation of stiff yet multifunctional three-dimensional porous carbon architecture at very low cost is still challenging. In this work, lightweight and foam (CF) with adjustable pore structure was prepared by using flour as the basic element via a simple fermentation carbonization process. compressive strength CF exhibits high value 3.6 MPa whereas its density 0.29 g/cm3 (compressive modulus can be 121 MPa). electromagnetic interference (EMI) shielding effectiveness measurements...
Electromagnetic interference (EMI) shielding materials for electronic devices in aviation and aerospace not only need lightweight high effectiveness, but also should withstand harsh environments. Traditional EMI often show heavy weight, poor thermal stability, short lifetime, tolerance to chemicals, are hard-to-manufacture. Searching high-efficiency overcoming the above weaknesses is still a great challenge. Herein, inspired by unique structure of natural wood, highly anisotropic...
Currently, electromagnetic radiation and interference have a significant effect on the operation of electronic devices human health systems. Thus, developing excellent microwave absorbers huge significance in material research field. Herein, kind ultrafine zinc oxide (ZnO) nanoparticles (NPs) supported three-dimensional (3D) ordered mesoporous carbon spheres (ZnO/OMCS) is prepared from silica inverse opal by using phenolic resol precursor as source. The lightweight ZnO/OMCS nanocomposites...
Assembling Ti3C2Tx MXene nanosheets into three-dimensional (3D) architecture with controllable alignment is of great importance for electromagnetic wave absorption (EMA) application. However, it a challenge to realize due the weak van der Waals interconnection between nanosheets. Herein, we propose introduce gelatin molecules as "chemical glue" fabricate 3D Mxene@gelatin (M@G) nanocomposite aerogel using unidirectional freeze casting method. The are well aligned in M@G aerogel, yielding much...
Abstract A complex electromagnetic environment is a formidable challenge in national defense areas. Microwave‐absorbing materials are considered as strategy to tackle this challenge. In work, lightweight, flexible, and thermal insulating Carbon/SiO 2 @CNTs (CSC) aerogel successfully prepared coupled with outstanding microwave absorbing performance, through freeze‐drying high‐temperature annealing techniques. The CSC shows strong reflection loss (−55.16 dB) well wide effective bandwidth (8.5...
