Preparation and microwave absorption properties of FeNi/graphite nanocomposites YANG Li(杨 丽), HE Huan(何 欢), LIU Hong-bo(刘洪波), ZOU Yan-hong(邹艳红), CHEN Hui(陈 惠), ZHOU Ru-quan(周如全) College of Materials Science and Engineering, Hunan University, Changsha 410082, China Received 15 July 2007; accepted 10 September 2007 Abstract: FeNi/graphite nanocomposites were prepared......
characteristics of carbon atoms on the edge and basal plane were determined by analyzing structure of graphite crystal and bond of different carbon atoms. The results show that the atoms on the edge are more...) on the edge are faster, and tighter SEI is formed there. A hexagonal close-packed model for graphite particle was developed. The fraction of carbon atoms on the surface and edge was derived in expression......
同石墨组成试样的表面形貌 Fig. 2 Surface morphologies of samples with different graphite 图3所示为铜与石墨简单堆积的截面图.其中,将石墨与铜颗粒以球形近似,并忽略接触过程中的弹性和塑性变形.对于不同粒度石墨组成的试样而言,铜与石墨的堆积情况是不同的[11].由图3可知,当石墨总量一定时,随着石墨粒度的减小,每个石墨颗粒与铜...石墨往往无法实现均匀的混合,因此,在图2(a),(b)和(c)中可以明显观察到局部的石墨聚集区.而对于添加沥青石墨的试样D(见图2(d))而言,粘结剂能给铜和石墨提供足够的粘结力,在混料过程中改善了石墨与铜的均匀分布. 图3 石墨-铜堆积截面 Fig. 3 Section of accumulation of copper and graphite particles 在......
