Although multifunctional, flexible, and wearable textiles with integrated smart electronics have attracted tremendous attention in recent years, it is still an issue to balance new functionalities with the inherent performances of the textile substrates. 2D early transition metal carbides/nitrides (MXenes) are considered as ideal nanosheets for fabricating multifunctional and flexible textiles on the basis of their superb intrinsic electrical conductivity, tunable surface chemistry, and layered structure. Herein, highly conductive and hydrophobic textiles with exceptional electromagnetic interference (EMI) shielding efficiency and excellent Joule heating performance are fabricated by depositing in situ polymerized polypyrrole (PPy) modified MXene sheets onto poly(ethylene terephthalate) textiles followed by a silicone coating. The resultant multifunctional textile exhibits high electrical conductivity of ≈1000 S m⁻¹ in conjunction with an exceptional EMI shielding efficiency of ≈90 dB at a thickness of 1.3 mm. The thin silicone coating renders the hydrophilic PPy/MXene‐decorated textile hydrophobic, leading to an excellent water‐resistant feature while retaining a satisfactory air permeability of the textile. Interestingly, the multifunctional textile also exhibits an excellent moderate voltage‐driven Joule heating performance. Thus, the deposition of PPy‐modified MXene followed by silicone coating creates a multifunctional textile that holds great promise for wearable intelligent garments, EMI shielding, and personal heating applications.

具有出色的电磁干扰屏蔽和焦耳加热性能的多功能耐水MXene装饰的聚酯纺织品

尽管近年来，具有集成智能电子功能的多功能，柔性和可穿戴纺织品引起了极大的关注，但是在新功能与纺织品基质的固有性能之间取得平衡仍然是一个问题。2D早期过渡金属碳化物/氮化物（MXenes）基于其极好的固有电导率，可调节的表面化学性质和分层结构，被认为是制造多功能和柔性纺织品的理想纳米片。在此，通过将原位聚合的聚吡咯（PPy）改性的MXene片材沉积到聚对苯二甲酸乙二醇酯织物上，然后再涂覆有机硅涂层，从而制造出具有出色的电磁干扰（EMI）屏蔽效率和出色的焦耳加热性能的高导电性和疏水性织物。^-1，在1.3 mm的厚度下具有≈90dB的出色EMI屏蔽效率。薄的有机硅涂层使亲水性PPy / MXene装饰的纺织品具有疏水性，从而在保持纺织品令人满意的透气性的同时，具有出色的防水功能。有趣的是，多功能纺织品还表现出出色的适度电压驱动的焦耳加热性能。因此，先沉积PPy改性的MXene，再进行有机硅涂层，可形成一种多功能纺织品，在可穿戴智能服装，EMI屏蔽和个人取暖应用方面具有广阔的前景。
