Abstract

High dielectric constant nanoparticles into polymer matrices have attracted much attention because this process can improve the nanofriction generator performance. However, the dispersion of the developed materials remains a challenge. In this paper, we present a novel high-performance nanofriction generator (FBT-TENG) based on composite nanoparticles of Amino-functionalized barium titanate and functionalized graphite oxide (FGO/ABTO) with Polyimide (PI) as substrate, which can be used as a sensor for intelligent monitoring systems. Specifically, we introduced amino groups on the surface of barium titanate to improve its dispersion in the PI solution, and the dual effect composite with functionalized graphite oxide improved the TENG performance of the PI film. Due to the FGO/ABTO synergy, the FBT-TENG can generate high output voltages, currents and power densities of 75 V, 13 µA and 4.6 W/m², respectively, which is a 9 times increase in power density compared to the original PI film. FBT-TENG is capable of powering capacitors. In addition, the FBT-TENG can be used as a sensor to build an early Parkinson’s disease detection system, which provides a more convenient option for the early diagnosis of Parkinson’s patients and has the potential for a wide range of medical applications.

采用胺化钛酸钡复合纳米粒子的高性能三电纳米发电机用于帕金森病的早期诊断

将高介电常数纳米粒子加入聚合物基质的工艺可以提高纳米摩擦发生器的性能，因此备受关注。然而，所开发材料的分散性仍然是一个挑战。本文介绍了一种新型高性能纳米摩擦发生器（FBT-TENG），它基于氨基功能化钛酸钡和功能化氧化石墨（FGO/ABTO）的复合纳米粒子，以聚酰亚胺（PI）为基底，可用作智能监控系统的传感器。具体来说，我们在钛酸钡表面引入了氨基，以改善其在 PI 溶液中的分散性，而与功能化氧化石墨的双效复合则提高了 PI 薄膜的 TENG 性能。由于 FGO/ABTO 的协同作用，FBT-TENG 可以产生高输出电压、电流和功率密度，分别达到 75 V、13 µA 和 4.6 W/m2，与原始 PI 薄膜相比，功率密度提高了 9 倍。FBT-TENG 能够为电容器供电。此外，FBT-TENG 还可用作传感器，构建早期帕金森病检测系统，为帕金森病患者的早期诊断提供更便捷的选择，具有广泛的医疗应用潜力。

期刊介绍： The Chemical Engineering Journal is an international research journal that invites contributions of original and novel fundamental research. It aims to provide an international platform for presenting original fundamental research, interpretative reviews, and discussions on new developments in chemical engineering. The journal welcomes papers that describe novel theory and its practical application, as well as those that demonstrate the transfer of techniques from other disciplines. It also welcomes reports on carefully conducted experimental work that is soundly interpreted. The main focus of the journal is on original and rigorous research results that have broad significance. The Catalysis section within the Chemical Engineering Journal focuses specifically on Experimental and Theoretical studies in the fields of heterogeneous catalysis, molecular catalysis, and biocatalysis. These studies have industrial impact on various sectors such as chemicals, energy, materials, foods, healthcare, and environmental protection.
