Abstract
Structural improvement of a bio-inspired 3D globular carbon foam by a continuously thermal treatment: A comprehensive study
Highlights
Since the discovery of carbon nanostructures such as carbon nanotubes (CNTs) [1] and graphene [2] the interest increases to use such materials for several applications, e.g. sensors [3], bioimplantats [4], composites [5,6,7] and batteries [8]
We show for the first time the effect of high temperature annealing as a function of the treatment temperature on the electrical and morphological properties of 3D carbon structures, called Globugraphite
We examine the extent to which graphitization influences temperature stability and the electrical conductivity
Summary
Since the discovery of carbon nanostructures such as carbon nanotubes (CNTs) [1] and graphene [2] the interest increases to use such materials for several applications, e.g. sensors [3], bioimplantats [4], composites [5,6,7] and batteries [8]. Assembly of graphitic structures [13,14,15,16] can be carried out One of these methods was the discovery of Aerographite [11]. The growth process of carbon nanostructures leads to the formation of defective points at the atomic level during the arrangement of carbon atoms. These defects reduce the mechanical [22,23] as well as the electrical [24] properties of carbon structures. To high-temperature graphitization, first annealing processes with graphene could be observed at a temperature of up to 600°C [27].
