Design and Fabrication of Modulus Graded Multi-Layer-Polymer Film for Application to Mechanically Robust Substrate Platform of Stretchable Electronics |
| 초록 |
Stretchable electronics based on geometrically/structurally protected inorganic materials are considered to offer great advantages for seamless human-device integration in the various fields due to their outstanding electrical performance. However, there is still a challenge in practical use, that mechanically vulnerable device integration due to unstable interfaces of large modulus/thermal expansion mismatch between rigid-soft materials. Herein, the multi-layer polymer film (MLPF) with gradient of mechanical and thermal properties was designed and fabricated in order to improve the mechanical durability and the processability through iCVD process. The MLPF effectively alleviates the interfacial instability and result in superb mechanical robustness. The MLPF was realized on the elastomer with an array pattern and was utilized for an application of amorphous Indium-Gallium-Zinc oxide (a-IGZO) based stretchable TFTs. |
