Construction of Ni@polypyrrole nanochains/Ti3C2Txternary composites with excellent microwave absorption properties

Ni@PPy NCs/Ti 3 C 2 T x ternary composites are successfully fabricated by the combination of solvothermal method, hydrothermal method and vacuum-assisted filtration, showing the optimum RL min of −62.61 dB at 6.82 GHz and 2.71 mm.
