论文摘要
3D打印技术为开发储能设备提供了一种创新的方法，以创建用于现代电子产品的便捷和低成本定制电极。通过在二维（2D）材料上移动一滴离子溶液来产生电势是一种新颖的雨能收集方法。这项工作证明了基于液体固定接触电气的3D印刷纳米生成器，雨滴通过带正电荷的超薄特尿酸（GD2TE3）板。实验结果表明，通过在装饰的3D打印纳米发育仪上移动一滴离子溶液，可以产生高达〜0.6 V的电压。通过增强大量3D印刷多孔结构的表面积，纳米发育仪的输出效率提高了约400％。进行了密度功能理论（DFT）计算，表明GD2TE3的（112）表面的高电导率是由于p型荷载体。此外，我们通过使用石墨杆并任意操纵表面电荷来说明输出性能（〜0.8V）的增强。因此，这项工作可以开辟一条新的途径，以推动对蓝色能源收集的科学研究并应对能源危机。
The 3D printing technology offers an innovative approach for developing energy storage devices to create facile and low-cost customized electrodes for modern electronics. Generating electric potential by moving a droplet of ionic solution over two-dimensional (2D) materials is a novel method for rain energy harvesting. This work demonstrated a liquid-solid contact electrification-based 3D printed nanogenerator where raindrop passes through the positively charged ultrathin Gadolinium Telluride (Gd2Te3) sheets. Experimental results showed that voltage as high as ~0.6 V could be generated by moving a droplet of ionic solution on the decorated 3D printed nanogenerator. The output efficiency of the nanogenerator is increased ~400% by enhancing the surface area of copious 3D printed porous structures. Density Functional Theory (DFT) calculations are done, revealing that the high electrical conductivity of (112) surface of Gd2Te3 is due to the p-type charge carriers. Additionally, we illustrate the enhancement of the output performance (~0.8V) by using a graphite rod and arbitrarily manipulating the surface charge. Therefore, this work can open up a new avenue to advance scientific research of Blue energy harvesting and tackle the energy crisis.
