摘要

MXene and conductive polymers are attractive candidates for electromagnetic interference shielding (EMI) applications. The MXene–PAT-conductive polymer (CP) composites were fabricated by a cost-effective spray coating technique and characterized using X-ray photoelectron spectroscopy (XPS), scanning electron microscopy (SEM), X-ray diffraction (XRD) and Raman spectroscopy. A new approach has been developed for the synthesis of exfoliated MXene. The MXene–PAT–poly( p -aminophenol)–polyaniline co-polymer composite exhibited good electric conductivity (EC) of 7.813 S cm ~(?1) . The composites revealed an excellent thermal properties, which were 0.687 W (m K) ~(?1) thermal conductivity, 2.247 J (g K) ~(?1) heat capacity, 0.282 mm ~(2) s ~(?1) thermal diffusivity and 1.330 W s ~(1/2) m ~(?2) K ~(?1) thermal effusivity. The composites showed 99.99% shielding efficiency and the MXene–PAT–PANI–PpAP composite (MXPATPA) had EMI shielding effectiveness of 45.18 dB at 8.2 GHz. The reduced form of MXene (r-Ti _(3) C _(2) T _( x ) ) increased the shielding effectiveness (SE) by 7.26% and the absorption (SE _(A) ) was greatly enhanced by the ant farm like structure. The composites possess excellent thermal and EMI SE characteristics, thus can be applied in areas, such as mobile phones, military utensils, heat-emitting electronic devices, automobiles and radars.
