FINE CARBON SHEET LAMINATE HAVING STRUCTURE OF WEEK INTERLAMINAR BONDING FORCE AND METHOD FOR PREPARATION THEREOF

摘要

A fine carbon sheet laminate having a structure of week interlaminar bonding force, wherein at least two graphene sheets composed of carbon atoms having a long side of 100 nm or more and a short side of 3 nm or more are laminated, respective layers have long sides of a similar length and short sides being different in length, respective groups of carbon atoms constituting two adjacent layers coordinate with each other in a relationship exhibiting no crystallinity in the C0 direction, two layers are bonded with each other with a bonding force weaker than the van der Waals force required for forming a graphite structure, the distance between two adjacent layers is 0.344 nm or more, and chiralities of respective layers are combined at random; and a method for preparing the fine carbon sheet laminate which comprises pyrolyzing an organic compound containing a Group VI element of the Periodic Table in the presence of a transition metal ultra-fine particle catalyst.
