摘要
物联网(IoT)技术的兴起增加了对玻璃电子器件的需求。然而,玻璃电子产品的生产需要复杂的工艺,包括导电材料涂层和化学气相沉积,这需要使用额外的化学品。因此,这引发了有关化学和电子废物的环境问题。本研究提出了一种快速、经济、简单的方法,以满足对玻璃电子产品日益增长的需求,同时解决与玻璃电子产品生产工艺相关的环境问题。该方法包括将聚酰亚胺(PI)带转化为激光诱导石墨烯(LIG),并使用紫外激光直接写入技术将其转移到玻璃基板上。这种工艺无需在环境空气中进行额外的化学处理,就能制造出嵌入石墨烯的玻璃。随后,残留的 PI 带被去除,从而得到了电阻率为 1.065 × 10-3 Ω m 的 LIG 玻璃电极。这些 LIG 电极在除雾、加热、温度传感和太阳能取暖等窗户应用方面展示了高效的功能,适用于汽车和住宅窗户。这种生态友好型技术在基于物联网的智能和可持续窗户电子设备方面的潜在可扩展性进一步突出了其满足不同用户需求的适应性。
In Situ Transfer of Laser-Induced Graphene Electronics for Multifunctional Smart Windows
The ascent of internet of things (IoT) technology has increased the demand for glass electronics. However, the production of glass electronics necessitates complicated processes, including conductive materials coating and chemical vapor deposition, which entail the use of additional chemicals. Consequently, this raises environmental apprehensions concerning chemical and electronic waste. In this study, a fast, cost-effective, and simple approach are presented to meet the growing demand for glass electronics while addressing environmental concerns associated with their production processes. The method involves converting polyimide (PI) tape into laser-induced graphene (LIG) and transferring it onto a glass substrate using ultraviolet laser direct writing technology. This process allows for the fabrication of LIG-embedded glass without additional chemical treatments in ambient air. Subsequently, the residual PI tape is removed, resulting in LIG-based glass electrodes with an electrical resistivity of 1.065 × 10−3 Ω m. These LIG electrodes demonstrate efficient functionality for window applications such as defogging, heating, temperature sensing, and solar warming, suitable for automotive and residential windows. The potential scalability of this eco-friendly technology to IoT-based smart and sustainable window electronics further underscores its adaptability to meet diverse user needs.
