Abstract We studied the electric and ferroelectric properties of reduced graphene oxide/lead titanate (PbTiO3) hybrids synthesized by the hydrothermal processes. The samples were characterized by X-ray diffraction, differential scanning calorimetry, Fourier transform IR spectroscopy, Raman spectroscopy, and high-resolution transmission electron microscopy. Additionally, the DC electrical properties and the conduction mechanism were explored in a wide temperature range (300–817 K). Furthermore, the measurements were extended to measure the pyroelectric behavior in an extended temperature range. Additionally, calculation with the aid of the pyroelectric current was done to obtain the ferroelectric polarization as a function of temperature.

还原氧化石墨烯促进 PbTiO3 的电传输特性

摘要 我们研究了水热法合成的还原氧化石墨烯/钛酸铅 (PbTiO3) 杂化物的电学和铁电性能。样品通过 X 射线衍射、差示扫描量热法、傅里叶变换红外光谱、拉曼光谱和高分辨率透射电子显微镜进行表征。此外，在较宽的温度范围内（300-817 K）探索了直流电特性和导电机制。此外，测量被扩展到测量在扩展的温度范围内的热电行为。此外，借助热电流进行计算以获得作为温度函数的铁电极化。
