Abstract

This study presents a method for fabricating a film-based heating element using a polymer material with an array of intersecting conductive elements embedded within it. Track-etched membranes (TM) with a thickness of 10m were used as the template, and their pores were filled with metal, forming a three-dimensional grid. Due to the unique manufacturing process of TM, the pores inside intersect with each other, allowing for contacts between individual nanowires (NWs) when filled with metal. Experimental results demonstrated that filling the TM pores with silver allows for heating temperatures up to 78 degrees without deformation or damage to the heating element. The resulting flexible heating element can be utilized in medical devices for heating purposes or as a thermal barrier coating.

摘要

本研究提出了一种使用聚合物材料制造基于薄膜的加热元件的方法，该聚合物材料中嵌入了一系列相交的导电元件。使用厚度为10微米的径迹蚀刻膜（TM）作为模板，其孔隙填充金属，形成三维网格。由于TM独特的制造工艺，内部孔隙相互交叉，填充金属时单个纳米线（NWs）之间能够实现接触。实验结果表明，用银填充TM孔隙可使加热温度高达78摄氏度，且加热元件不会变形或损坏。所得的柔性加热元件可用于医疗设备的加热用途或用作热障涂层。
