Synthesis of Stretchable and Self-healing Electroconductive Composites Using Supramolecular Organic Polymer Embedded with Copper Microparticles |
| 초록 |
Inspired from the healing mechanism of human skin and other biological systems, researchers are working on self-healing materials which have enormous applications starting from healthcare (like e-skin, e-nose, and e-tongue) to many other fields (e.g., wearable devices, soft robotics, and synaptic devices). It is still a great challenge to develop an ordinary self-healing electronic device because all the components of that device should be electrically and mechanically self-healable and stretchable as well. Here, our development of a new self-healing semiconducting composite based on supramolecular organic polymer and copper microparticles is introduced. It is highly stretchable (over 200%) and shows an excellent self-healing ability of electrical and mechanical properties at ambient conditions within just 5 minutes. Its healing ability is about 75%~87% for mechanical property and nearly 100% for electrical properties. Maintaining optimal healing of mechanical property, its sheet resistance and electrical conductivity are found in the range of a semiconductor, 2.88 Ω/sq and 5.14 S/cm respectively. Its electrical conductivity can be restored upon 5 repeated cutting-healing cycles and also tunable by varying the copper loading. These results demonstrate the potential of our self-healing material for developing self-healing semiconducting devices and show promising directions in the field of sustainable electronics. |
