This research explores the development of highly durable flexible electronic textiles (e-textiles) for wearable electronics, focusing on improving their washability and performance. A conductive graphene-based ink was screen-printed onto a polyester textile. Water-based polyurethane (PU) coatings with variable crosslinker ratios and thickener were applied to solve washability issues. The results show that the PU coatings significantly enhanced the electrical stability and durability of the printed pathways after multiple washing cycles. The conductivity remained intact after 120 washing cycles, indicating that the final properties of the e-textile, which contained 6 wt% thickener and 3 wt% crosslinker, provided effective water protection. The results highlight the promise of these coated e-textiles for wearable electronics applications, especially in the occupational and healthcare sectors, where long-term flexibility and washability are critical.
本研究探索用于可穿戴电子设备的高耐用柔性电子织物（电子织物）的发展，重点在于提高其可洗性和性能。一种基于石墨烯的导电油墨被丝网印刷到聚酯织物上。应用具有可变交联剂比例和增稠剂的水性聚氨酯（PU）涂层来解决可洗性问题。结果表明，PU涂层在多次洗涤循环后显著提高了印刷线路的电稳定性和耐久性。在120次洗涤循环后电导率保持不变，这表明含有6重量%增稠剂和3重量%交联剂的电子织物的最终性能提供了有效的防水保护。这些结果突出了这些涂层电子织物在可穿戴电子设备应用中的前景，特别是在职业和医疗保健领域，其中长期的柔韧性和可洗性至关重要。
