Conductive paper has low-cost, lightweight, sustainability, easy scale-up, and tailorable advantages, allowing for its promising potential in flexible electronics, such as bendable supercapacitors, solar cells, electromagnetic shields, actuators. Ionic gels, exhibiting a lower Young’s modulus together with facile manufacturing, can fully serve the conductive component to prepare paper. Herein we report low-cost (∼1.3 dollars/m2), continuous, high-throughput (up ∼30 m/min) fabrication of reliable long-term (stable more than two months) As-prepared shows high electrical durability negligible bending–recovering signal changes over 5000 cycles. Using this ionic gel (IGP) key component, build variety proof-of-principle demonstrations show capacity IGP constructing electroluminescent devices diverse patterns, including square, an alphabetic string, laughing face. Our methodology open new powerful route fabricate myriad applications future electronics.
