膨胀石墨的孔隙结构-中国国家自然科学基金和日本学术振兴会联合研究项目报道

通过对膨胀石墨膨化容积，石墨蠕虫之间和内部孔隙尺寸的测定，详细研究了膨胀石墨的孔结构，建立了一些估测孔结构的新技术；为了研究膨胀石墨的孔结构，发展了一些测量新技术：包括石腊浸渍法，将石墨蠕虫浸渍在液态石蜡中，石蜡就会填充石墨间的大孔隙，通过断裂方法还可以看到蠕虫内部孔隙，这些方法均需要借助图像处理技术。本论文第一部分分析了市售膨胀石墨的孔隙结构，第二和第三部分分别讨论了胀化温度和插层剂对孔结构的一些影响。

Pore structure of exfoliated graphite- A report on a joint research project under the scientific cooperation program between NSFC and JSPS

The pore structure of exfoliated graphite was discussed on the basis of exfoliation volume, and size determination of pores among and inside the worm-like particles. In order to evaluate pore structures, new techniques were developed, which included a paraffin impregnation method for filling large spaces between the particles and fracturing across the worm-like particles for pores inside the particles, both being assisted by an image processing technique. In the first part of the present review, the pore structure of a commercially available exfoliated graphite was determined. In the second and third parts, the effects of exfoliation temperature and intercalate content are respectively discussed.
