摘要：

Electromagnetic interference (EMI) shielding fabric is widely used to deal with radiation pollution. However, the traditional EMI shielding fabrics are limited by their reflection-dominated shielding mechanism, large loading and poor shielding performance. Herein, Ti3C2Tx coated cotton fabrics with low Ti3C2Tx loading (1.5-2.6mg/cm(2)) were prepared through a facile vacuum filtration process. Ti3C2Tx coated cotton fabric exhibits excellent electrical conductivity (up to 1570S/cm), EMI SE (up to 48.9dB) and superior shielding efficiency (up to 2969dBcm(2)/g) with a low Ti3C2Tx loading (2.6mg/cm(2)) in the frequency of 2-18GHz. Especially, Ti3C2Tx coated cotton fabric shows high ratio of absorption shielding efficiency (SEA)/reflection shielding efficiency (SER) (>9) in the frequency of 2-13.5GHz, indicating that the dominant shielding mechanism of Ti3C2Tx coated cotton fabrics is microwave absorption of EM radiation. Additionally, the Ti3C2Tx coated cotton fabric exhibits a high tensile strength (up to 70N) and fracture elongation (up to 18.3%). The result suggests that the Ti3C2Tx coated cotton fabric is a superior absorption-dominated EMI shielding material. The Ti3C2Tx coated cotton fabric with low loading, robust, and highly conductive properties can be regarded as an alternative electromagnetic wave absorbing material. [GRAPHICS]
