蜂蜜不仅用于人类营养，最近也被研究为一种有前途的生物材料，有可能用作设备中的可持续介质膜[1-2]。我们在此报告了由蜂蜜与碳纳米管（CNTs）混合制成的薄膜的表征，旨在研究用于忆阻器器件的薄膜的可隧穿性。调节蜂蜜-碳纳米管薄膜的厚度和碳纳米管的浓度对器件的性能起着至关重要的作用。虽然包括蜂蜜-碳纳米管薄膜在内的生物材料的结构表征具有挑战性，但我们展示了几种表征技术的战略组合，以系统地研究蜂蜜基薄膜中不同碳纳米管浓度和退火时间对薄膜结构的影响。样品由蜂蜜、水和CNTs三种浓度的混合物制备：0.05、0.1和0.2 mg/mL。薄膜在熔融石英上自旋涂覆，并在90℃下分别退火0小时、4小时和12小时。采用光学显微镜、激光扫描共聚焦显微镜（Keyence VK-X3000）和拉曼光谱（Horiba Jobin Yvon HR800）进行表征。
Honey is not only used for human nutrition but is also being studied lately as a promising biomaterial with potential for use as a sustainable dielectric film in devices [1-2]. We report here the characterization of films made of honey mixed with carbon nanotubes (CNTs), aimed at tunnelable properties of the films for memristor device applications. Tuning the honey-CNT film thickness and the concentration of the CNTs will play a vital role in the performance of the device. While the structural characterization of biomaterials including the honey-CNT films is challenging, we demonstrate a strategic combination of several characterization techniques to systematically investigate the effects of different CNT concentrations in honey-based films and the annealing durations on the structures of the films.The samples were prepared as an admixture of honey, water and CNTs at three concentrations: 0.05, 0.1, and 0.2 mg/mL. Films were spin-coated on fused-quartz and annealed at 90 C for 0 hrs, 4 hrs, and 12 hrs, respectively. Optical microscopy, laser scanning confocal microscopy (Keyence VK-X3000), and Raman spectroscopy (Horiba Jobin Yvon HR800) were used for characterization.
