Abstract

In this work, we approached sintering and crystallization of soyabean powders with a “cold sintering” approach to develop a bioelectret for potential high-frequency communication applications. Structural disintegration and phase evolution of glycinin globulin proteins present in soyabean powders in relation to sintering parameters were investigated using X ray diffraction (XRD), Fourier transform infrared (FTIR) spectroscopy, and thermogravimetry analysis (TGA). Piezoresponse force microscopy (PFM) showed some localized area with weak (0.7 pm/V) to reasonable (2.7 pm/V) out of plane piezoresponse in cold pressed and sintered soyabeans, respectively. Sintered bioelectrets did not show any macroscopic piezoelectricity, however.

烧结大豆粉的可持续电介质：结构、热和压电特性

在这项研究中，我们采用 "冷烧结 "方法对大豆粉末进行烧结和结晶，以开发一种具有高频通信应用潜力的生物驻极体。我们使用 X 射线衍射 (XRD)、傅立叶变换红外光谱 (FTIR) 和热重分析 (TGA) 研究了大豆粉末中甘氨酸球蛋白的结构解体和相变与烧结参数的关系。压电响应力显微镜（PFM）显示，冷压大豆和烧结大豆中的一些局部区域分别具有微弱（0.7 pm/V）到合理（2.7 pm/V）的平面外压电响应。然而，烧结生物电极并未显示出任何宏观压电性。
