Journal ArticleDOI
Lightweight Ti2CTx MXene/Poly(vinyl alcohol) Composite Foams for Electromagnetic Wave Shielding with Absorption-Dominated Feature
TL;DR: Comparison experiment reveals that the good impedance matching derived from the multiple porous structures, internal reflection, and polarization effect plays a synergistic role in the improved absorption efficiency and superior EMI shielding performance.
Journal ArticleDOI
Mesoporous carbon hollow microspheres with red blood cell like morphology for efficient microwave absorption at elevated temperature
Hailong Xu,Xiaowei Yin,Minghang Li,Fang Ye,Meikang Han,Zexin Hou,Xinliang Li,Litong Zhang,Laifei Cheng +8 more
TL;DR: Red blood cell like-mesoporous carbon hollow microspheres (RBC-PCHMs) have been synthesized by modified stober method with following pyrolysis and etching procedures.
Journal ArticleDOI
Constructing hollow graphene nano-spheres confined in porous amorphous carbon particles for achieving full X band microwave absorption
TL;DR: In this article, a kind of hollow graphene nano-spheres uniformly confined in porous amorphous carbon particles (HGS@PAC) are fabricated via a facile pyrolysis of bi-metal organic framework (bi-MOF).
Journal ArticleDOI
Ultralight MXene-Coated, Interconnected SiCnws Three-Dimensional Lamellar Foams for Efficient Microwave Absorption in the X-Band
Xinliang Li,Xiaowei Yin,Hailong Xu,Meikang Han,Minghang Li,Shuang Liang,Laifei Cheng,Litong Zhang +7 more
TL;DR: Order lamellar f-Ti3C2T X/SiCnws hybrid foams with ultralow density are synthesized by a combination of self-assembly and bidirectional freezing processes and exhibit excellent EM absorption properties superior to most of the current foam-based counterparts.
Journal ArticleDOI
