High-performance fiber strain sensor of carbon nanotube/thermoplastic polyurethane@styrene butadiene styrene with a double percolated structure
文献摘要：
In this work,a high-performance fiber strain sensor is fabricated by constructing a double percolated structure,consisting of carbon nanotube(CNT)/thermoplastic polyurethane(TPU)continuous phase and styrene butadiene styrene(SBS)phase,incompatible with TPU(CNT/TPU@SBS).Compared with other similar fiber strain sensor systems without double percolated structure,the CNT/TPU@SBS sensor achieves a lower percolation threshold(0.38 wt.％)and higher electrical conductivity.The conductivity of 1％-CNT/TPU@SBS(4.12×10-3 S·m-1)is two orders of magnitude higher than that of 1％-CNT/TPU(3.17×10-5 S·m-1)at the same CNT loading of 1 wt.％.Due to double percolated structure,the 1％-CNT/TPU@SBS sensor exhibits a wide strain detection range(0.2％-100％)and an ultra-high sensitivity(maximum gauge factor(GF)is 32411 at 100％strain).Besides,the 1％-CNT/TPU@SBS sensor shows a high linearity(R2=0.97)at 0％-20％strain,relatively fast response time(214 ms),and stability(500 loading/unloading cycles).The designed sensor can efficiently monitor physiological signals and movements and identify load distribution after being woven into a sensor array,showing broad application prospects in wearable electronics.
