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.
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.
