共轭静电纺碳黑掺杂PLLA/PDLA压电织物的制备及性能研究
Preparation and performance study of PLLA/PDLA piezoelectric fabrics doped with carbon black by conjugated electrostatic spinning
摘要
Abstract
In order to obtain piezoelectric smart fabric with excellent piezoelectric property,conjugated electrostatic spinning method was adopted,copper fiber was used as the conductive core,left-handed polylactic acid(PLLA)and right-handed polylactic acid(PDLA)were blended,and adding carbon black powder with different mass fractions to prepare the yarn then woven high-performance piezoelectric fabric.The prepared yarn and fabric were characterized by scanning electron microscopy,X-ray photoelectron spectroscopy,universal strength testing machine and piezoelectric testing device.The results indicated that the addition of carbon black could significantly improve the piezoelectric property of the fabric.When the carbon black doping ratio was 0.5%,the electrospinning voltage was 6.5 kV,the distance between the two needles was 18 cm,and spinning distance was 12 cm,the prepared fabric exhibited the best piezoelectric performance,the maximum output voltage of the fabric was 16.6 V,the current was 225.55 nA,and output performance was stable.It is considered that the piezoelectric fabric can monitor human motion signals and has great application potential in wearable devices,health monitoring and other fields.关键词
