The conference shall gather the international scientific community working in the field of carbon nanotube, graphene, or other nanocarbon filled composites. These materials are summarized as carbon nanoparticles (CNPs) which explains the change from the conference title CNTComp (so far) to CNPComp (starting in 2013). The conference provides the forum where the latest results and findings in the field will be presented and offers researchers from both academic institutions and industry a great opportunity to exchange knowledge, make contacts and engage in discussions.
