High Strength Metallurgical Graphene – Mechanisms of Growth and Properties / Grafen Metalurgiczny O Wysokiej Wytrzyma?o?ci – Mechanizmy Wzrostu I W?a?ciwo?ci

摘要

In this work, the growth mechanisms of chemical vapor deposited and metallurgical graphene and their selected mechanical and electrical properties were investigated. The study revealed the influence of the growth mechanisms on monoand poly-crystalline nanostructures of synthesized graphene monolayers. The structure of flake boundaries greatly affects both the mechanical and electrical properties. The key factors are overlapping of the graphene flakes, their degree of mismatch and the presence of π type bonds. All of these issues should be taken into account when developing industrially scaled technologies for graphene manufacturing.
