为研究可穿戴织物的电加热性能以及水洗对其性能的影响,通过简单安全可大规模产业化的无转移液相浸涂沉积法在涤纶针织物上沉积并原位还原,制备了还原氧化石墨烯(RGO)涂层织物加热器。借助扫描电子显微镜和傅里叶红外光谱仪对制备的RGO涂层涤纶织物进行表观形态与化学结构分析,同时研究了RGO涂层涤纶织物的导电、力学、电加热性能。结果表明:RGO涂层涤纶织物的电导率为430.9 mS/cm,在10 V电压下可达到65.58℃的稳定温度,最大升温速率为3.41℃/s;经过2次水洗循环后,在10 V的电压下,RGO涂层涤纶织物可达到43℃。本文研究表明,RGO涂层涤纶织物具有优异的电热性能,在医用电热、运动康复等领域具有良好的应用潜力。

In order to study the electrical heating properties of wearable fabrics and the influence of washing on their properties,a reduced graphene oxide(RGO)coated fabric heater was prepared through a simple,safe and industrial-scale liquid phase immersion deposition method that by depositing RGO on polyester knitted fabrics and for reduction in situ.The morphology and chemical structure of RGO coated polyester fabric were characterized by scanning electron microscopy and Fourier transform infrared spectrometer.The electrical conductivity,mechanical and electric heating properties of RGO coated polyester fabrics were also measured.The resulTSshow that the electrical conductivity of the RGO coated polyester fabric is 430.94 mS/cm.In addition,the RGO coated polyester fabric can reach a stable-state temperature of 65.58℃under a voltage of 10 V,and the maximum heating rate of 3.14℃/s.After two cycles of washing,the RGO coated polyester fabric can reach 43℃under 10 V applied voltage.This paper shows that the RGO coated polyester fabric has remarkable electrical heating properties with great application potentials in medical electrothermal,athletic rehabilitation and other fields.
