摘　　要：为制备基于涤/棉与导电锦纶长丝包缠复合纱的摩擦纳米发电机,以涤/棉混纺纱为皮层,导电锦纶长丝为芯层,通过空芯锭花式加捻技术,将涤/棉混纺纱均匀包缠在导电锦纶长丝上,得到基于复合纱的摩擦纳米发电机。通过研究基于包缠复合纱的摩擦纳米发电机的电量输出性能,结果表明:该摩擦纳米发电机具有优异的电学能量输出性能,其电量输出值随着复合纱长度的增加而增加,25 cm长可产生23.44 V的开路电压,短路电流和短路电荷量分别可达76.19 nA和7.86 nC;接触分离频率在0.5~2.5 Hz范围内,输出电量值随着频率的升高而不断增加;该发电机在1 Hz频率条件下循环1000次具有极好的稳定性。此类基于复合纱的摩擦纳米发电机可作为自供电传感器,用于摩斯密码的信息传递。Aiming at the creation of a tribo-electric nano-generator,a composite yarn,with the polyester-cotton blended yarns as the sheath layer and the conductive nylon filaments as the core layer,was prepared.A tribo-electric nano-generator was achieved by evenly wrapping the polyester-cotton blended yarns over the conductive nylon filaments using the hollow spindle fancy yarn technology.The electrical output of the tribo-electric nano-generator made from the composite yarn was studied.The results show thatnhe tribo-electric nano-generator demonstrated satisfactory electrical output,and the energy output value increases as the yarn length increases.The composite yarn with a length of 25 cm is shown to produce an open-circuit voltage of 23.44 V,and the short-circuit current and short-circuit charge reach 76.19 nA and 7.86 nC,respectively.Under the contact-separation frequency of 0.5 Hz~2.5 Hz,the output power value increases continuously with the increase of the frequency.The tribo electric nano generator maintained a stable work condition after reciprocating for 1000 cycles under 1 Hz frequency.This self-powered yarn based tribo-electric nano-generator can be used for information transmission of Morse code.
