Bidirectional, Multilayer MXene/Polyimide Aerogels for Ultra‐Broadband Microwave Absorption
Xi'an Jiaotong University · Key Laboratory of Nuclear Radiation and Nuclear Energy Technology
Abstract
Abstract To obtain high‐performance electromagnetic microwave (EM) absorption materials with broad effective absorption bandwidth ( EAB ) and reduced thickness, designing structures has proved to be a promising way. Herein, ultra‐broadband multilayer bidirectional MXene/polyimide EM absorption aerogels containing multi‐structures on scales ranging from the micro‐ to the macroscale are produced with the aid of electric and temperature fields. On the microscale, under the action of electric force and temperature gradient, the ordered structures made of aligned Ti 3 C 2 T x MXene nanosheets and the microscale layered aerogel walls enable the bidirectional aerogel to achieve a wide EAB of 8.58 GHz at a thickness…
