在这项研究中，我们基于使用室温离子液体（IL）进行导电预处理，成功获得了具有不同表面性质的碳纳米管（CNT）衍生物的扫描电子显微镜（SEM）图像。获得的 SEM 图像的质量取决于其表面特性和所用 IL 的亲水性。当样品表面和IL的亲水性接近时，获得的SEM图像具有高分辨率。相比之下，用离子液体预处理的样品的 SEM 图像与样品具有不同的亲水性，观察到的分辨率低且质量低。该结果表明两种亲水性之间的关系是该可视化方法的主导因素。
In this study, we succeeded in acquiring scanning electron microscope (SEM) images of carbon nanotube (CNT) derivatives with different surface properties based on an electro-conductive pre-treatment using a room temperature ionic liquid (IL). The quality of the obtained SEM images depended on their surface properties and the hydrophilicities of IL used. When the hydrophilicities of both the sample surface and the IL were close, the obtained SEM images had a high resolution. In contrast, SEM imges of samples pretreated with an IL, which had different hydrophilicities from the sample, was observed with low resolution and low quality. This result suggests that the relationship between both hydrophilicities is the dominant factor for this visualization method.
