Abstract
This study reports the use of a silane coupling agent (KH550) and sodium dodecyl benzene sulfonate (SDBS) for the modification of the MWCNTs to explore the influence of chemical modification on the piezoresistive performance of the flexible sensor film filled with multi-walled carbon nanotubes (MWCNTs). Modified MWCNTs and polyurethane (PU) were used to prepare the sensing materials. The fabric electrode was made of silver-plated yarn, and the film was assembled into a flexible piezoresistive sensor, following which it was integrated into the openings for fingers in the knitted gloves. The results revealed that the modification could significantly improve the electrical and mechanical properties of the MWCNTs. It could also be used to determine the forces generated by the hand during pressing, holding, etc. Thus, the sensor presents huge application prospects in the field of fabrication of wearable devices, medical detection, and electronic skin.
