Abstract

The invention relates to a preparation method of a PANI / MXene / carbon cloth composite wave absorbing material. The preparation method comprises following steps: adding carbon cloth, which has been processed by an acid, into an MXene solution, stirring, adding the obtained MXene / carbon cloth composite material into an acidic solution containing aniline, which can adhere on the surface of the carboncloth, and carrying out polymerization reactions. The conditions of the preparation method are mild; and the obtained material is light and thin, has high flexibility and an excellent wave absorbing performance, can be cut to prepare shield layers of radar or electronic devices, daily protective materials, and protective clothing for special occasions, and has great market demand and a wide application prospect.

Description

technical field [0001] The invention belongs to the field of preparation methods of flexible wave-absorbing materials, in particular to a method for preparing PANI / MXene / carbon cloth composite wave-absorbing materials. Background technique [0002] Driven by the new wave of technology, the whole world is developing rapidly, and the era of 5G intelligent society is coming, and our lives are undergoing rapid changes. The continuous development of electronic communication equipment, while bringing us great convenience, the resulting electromagnetic radiation also poses a huge hazard to our health and living environment, so "electromagnetic pollution" has become another hot topic today. Electromagnetic pollution is caused by the disordered super-intensity radiation of electromagnetic waves. In addition to natural electromagnetic pollution caused by natural factors such as cosmic rays, atmospheric lightning, thermal radiation from the sun and the earth, there are also electronic ...
