Printed flexible heaters (FHs) with excellent heating performance and thermal stability are quite desirable for the development of portable thermotherapy platform. Herein, the facile screen‐printing technology is used to fabricate the highly oxidation‐resistant Cu @ Ni rose‐stem nanowires (RSNWs) ‐ based low‐cost scalable FHs. The Cu @ Ni RSNWs possess low sheet resistance of 1.9 Ω sq−1 after low temperature sintering (90 °C). The FHs not only exhibit great oxidation resistance (almost no change at 180 °C for 30 min), but also maintain the great conductivity (ΔR /R 0 < 0.3) even after being exposed to ambient atmosphere for 60 days. Furthermore, the FHs exhibit great heating performance with the saturation temperature of 172.8 °C under 6 V, and can keep stable heating cycles for 5500 s under both parameters of the stepwise‐rising voltage from 2 to 6 V and consistent load‐on voltage of 6 V. In addition, the heaters array can greatly shorten the time of raising the temperature of the blood bag from 5 to 20 °C. The outstanding heating performance of the FHs provides great chances for portable variable‐area flexible heating platform in the field of multiduty thermal management.

印制的基于柔性加热器的热疗平台,用于多任务热管理

具有出色的加热性能和热稳定性的印刷柔性加热器(FH)非常适合便携式热疗平台的开发。此处,简便的丝网印刷技术用于制造高度抗氧化的Cu @ Ni玫瑰茎纳米线(RSNWs)基的低成本可扩展FH。经过低温烧结(90°C)后,Cu @ Ni RSNWs具有1.9Ωsq -1的低薄层电阻。FHs不仅表现出出色的抗氧化性(在180°C下30分钟几乎没有变化),而且保持了出色的电导率(ΔR / R 0<0.3),即使暴露在大气中60天也是如此。此外,FH具有出色的加热性能,在6 V下的饱和温度为172.8°C,并且在2到6 V的逐步上升电压和恒定的负载电压两个参数下都能保持5500 s的稳定加热周期。 6V。此外,加热器阵列可以大大缩短将血袋温度从5升高到20°C的时间。FH的出色加热性能为多任务热管理领域中的便携式可变区域柔性加热平台提供了巨大的机会。
