In this study, we report the successful fabrication of a novel antibacterial triboelectric nanogenerator (TENG) using a polymer composite film based on polyhexamethylene guanidine hydrochloride (PHMG). The composite materials, with optimised ingredient ratios, consist of PHMG, polyvinyl alcohol (PVA) and glutaraldehyde (GA) as a crosslinking agent (PHMG-GA-PVA). Utilising 3D printing, these composite materials were directly deposited on the conductive substrates and used as positive TENG electrodes. The obtained results show that the TENGs based on PHMG-GA-PVA exhibit high output efficiency, achieving peak-to-peak open-circuit voltage ( ) and short-circuit current ( ) values of 664.5 V and 116.8 μA, respectively, at a low operating frequency of 1 Hz with an actuation force of 10 N. The device retains approximately 98% of its initial output voltage value after 360 000 contact-release cycles.
在本研究中，我们报告了一种基于聚六亚甲基胍盐酸盐（PHMG）的聚合物复合膜成功制备出新型抗菌摩擦纳米发电机（TENG）。这些具有优化成分比例的复合材料由PHMG、聚乙烯醇（PVA）和作为交联剂的戊二醛（GA）组成（PHMG-GA-PVA）。利用3D打印技术，将这些复合材料直接沉积在导电基板上，并用作TENG的正电极。所得结果表明，基于PHMG-GA-PVA的TENG表现出高输出效率，在1 Hz的低工作频率和10 N的驱动力下，分别实现了664.5 V的峰峰值开路电压（ ）和116.8 μA的短路电流（ ）值。在360000次接触-释放循环后，该装置保留了其初始输出电压值的约98%。
