Study on the effect of CNT on the improved mechanical performance of flexible Ag NPs/CNT based electronics
Source abstract
Abstract
Flexible electronics such as flexible sensors play a significant role in the daily life. In this work, a simple sintering method was proposed to produce a flexible sensing component. In contrast with conventional Ag NPs based flexible conductive patterns, CNT enhanced flexible components were prepared, which can improve the sintering efficiency and mechanical durability against bending tests significantly. The effects of different CNT content in the composites on the electrical and mechanical performance were discussed. It was found the prepared samples with CNT wt% as 2% obtained improved mechanical durability and reliable electrical property against bending test for 20000 bending cycles in this work. Furthermore, the mechanism of CNT enhancement was discussed. Finally, a successful gesture detection application based on the prepared composites was demonstrated.
