摘要
针对现有发热丝柔性差、不耐水洗等问题,提出在涤纶纱线表面均匀涂覆碳纳米管的柔性发热丝制备方法。依据柔性发热丝制备工艺要求,设计了可在纱线表面均匀涂覆碳纳米管的实验系统。利用该系统在涤纶纱线表面进行均匀涂覆碳纳米管实验研究,并对所制备的发热丝进行电阻测量、微观形貌观察及发热性能测试。结果表明:采用这个实验系统可实现柔性发热丝的制备;长度为15 cm的发热丝平均电阻率为24.895Ω·cm,标准偏差为0.473Ω·cm;微观形貌照片显示涤纶纱线表面均匀涂覆了一层网状结构碳纳米管材料;在施加36 V电压下构建的并联网状结构表面4 min内可获得50.3℃的加热温度。
Aiming at the problem that the current heating wire has poor flexibility and insufficient washability,the conducting flexible heating wire was prepared by coating with carbon nanotubes on the surface of polyester yarn.According to the technology requirement of flexible heating wire preparation,the experimental system for uniform coating yarn was designed and applied in coating of carbon nanotubes on the surface of polyester yarn.The resistance and thermal properties were measured,and the microscopic image was observed.The results show that the experimental platform can realize the preparation of flexible heating wire,the average resistivity of the heating wire with a length of 15 cm is 24.895Ω·cm and the standard deviation is 0.473Ω·cm.The surface of the polyester yarn is uniformly coated with a layer of mesh structure carbon nanotube material.Under the application of 36 V voltage,the parallel network structure constructed by the heating wire surface can reach 50.3℃heating temperature within 4 min.
