Abstract Fibre‐based materials have received tremendous attention due to their flexibility and wearability. Although great efforts been devoted achieve high‐performance fibres over the past several years, it is still challenging for multifunctional macroscopic satisfy versatile applications. 2D transition metal carbides/nitrides (MXenes) with intriguing physical/chemical properties explored in broad application, may be able reinforce synthetic fibres. Inspired by natural materials, first time, flexible smart textiles are fabricated using a 3D printing process hybrid inks of TEMPO (2,2,6,6‐tetramethylpiperidine‐1‐oxylradi‐cal)‐mediated oxidized cellulose nanofibrils (TOCNFs) Ti 3 C 2 MXene. The display good rheological properties, which allow them accurate structures rapidly printed. TOCNFs/Ti self‐assemble an aligned structure ethanol, mimicking features plant In contrast conventional limited functions, exhibit significant responsiveness multiple external stimuli (electrical/photonic/mechanical). electromechanical performance can processed into sensitive strain sensors. Such will promising diverse applications, including wearable heating textiles, human health monitoring, human–machine interfaces.

Ultrarobust Ti₃C₂T_x MXene-Based Soft Actuators via Bamboo-Inspired Mesoscale Assembly of Hybrid Nanostructures

ACS Nano, Journal Year: 2020, Volume and Issue: 14(6), P. 7055 - 7065

Soft actuation materials are highly desirable in flexible electronics, soft robotics, etc. However, traditional bilayered actuators usually suffer from poor mechanical properties as well deteriorated performance reliability. Here, inspired by the delicate architecture of natural bamboo, we present a hierarchical gradient structured actuator via mesoscale assembly micro–nano-scaled two-dimentional MXenes and one-dimentional cellulose nanofibers with molecular-scaled strong hydrogen bonding. The resultant integrates high tensile strength (237.1 MPa), Young's modulus (8.5 GPa), superior toughness (10.9 MJ/m3), direct fast hygroscopic within single body, which is difficult to achieve actuators. proof-of-concept prototype robot demonstrated emphasize its robustness even after bending 100 000 times, kneading, or being trampled an adult (7 500 times heavier than crawling robot). This bioinspired strategy provides approach for application next-generation robust robotics.
