柔性全编织摩擦纳米发电织物的制备

为使柔性摩擦纳米发电机更好地贴合人体，且方便制备，将柔性摩擦纳米发电机进行服饰化。通过锥形 编织的方法将锦纶（PA6）与涤纶（PET）缝纫线分别缠绕在镀银的金属长丝表面，形成2 种皮芯结构的复合导电纤 维绳，其中皮层PA6与PET纤维缝纫线作为摩擦层，芯层镀银金属长丝作为电极层，将2 种复合导电纤维绳经机织 制备成柔性自供能织物作为摩擦纳米发电机，收集人体运动机械能并转化为电能，进而为可穿戴设备供电；同时对 该发电织物的表面形貌和输出性能进行表征。结果表明：这种摩擦纳米发电织物的开路电压为20.0 V，短路电流 为1.50 μA，瞬时功率最大为1.6 mW/m² ；该柔性摩擦纳米发电机由缝纫线编织而成，具有很好的柔性、透气性以及水洗性，材料廉价易得，且制备工艺简单。

Preparation of flexible all-braiding triboelectric nanogenerator

In order to well fit human body with flexible all-braided triboelectric nanogenerator(FTENG) and easily prepare FTNG, the FTNG was garmented.By using cone-spinningmethod, the skin-core structured composite yarns were formed by winding nylon (PA6) and polyester (PET) sewing yarn onto the surface of Ag fiber surface, respectively. These composite yarns were woven into self-powered fabrics with a shuttle, in which PA6 cortex cortex andPET were usedas friction layer and the core layer of Ag fiber was used as electrode for effective biomechanical energy harvesting and active wearable electronics. Based on the skin-core structured composite yarns and the advanced 2-D structural design, the open circuit voltage and short circuit current are 20.0V and 1.50μA, respectively, and the maximum peak power density can reach 1.6mW/m-2. In addition, the collected power iscapable of charging a commercial capacitor.
