However, achieving these mechanical properties while also maintaining high EMI shielding effectiveness (SE) for shielding materials remains a significant challenge. Here, a stretchable patterned carbon nanotube (CNT) array composite film, reinforced with two-dimensional (2D) nanomaterials (Ti<sub>3</sub>C<sub>2</sub>T<sub>x</sub> and graphene), is fabricated using a straightforward scraping method. The resulting CNT array/Ti<sub>3</sub>C<sub>2</sub>T<sub>x</sub>/graphene composite films possess a periodic grid structure. Specifically, the composite film with a regular hexagonal pattern demonstrates an EMI SE of 36.5 dB in thNanomaterials (Basel, Switzerland)Stretchable, Patterned Carbon Nanotube Array Enhanced by Ti<sub>3</sub>C<sub>2</sub>T<sub>x</sub>/Graphene for Electromagnetic Interference Shielding.PMC119020165207241552371247Liu XZheng JFeng JHuang JFu ZZeng ZLi BWang YGui XfalseStretchable, Patterned Carbon Nanotube Array Enhanced by Ti<sub>3</sub>C<sub>2</sub>T<sub>x</sub>/Graphene for Electromagnetic Interference Shielding.Stretchability and flexibility are essential characteristics for high-performance electromagnetic interference (EMI) shielding materials in wearable and smart devices.
