The GraphChina 2018 was held September 19 – 21 in Xi’an, China. The conference was divided into three parallel symposia, focusing on different topics like graphene and 2D materials frontier research, graphene-related emerging industries and graphene application in traditional industries. During the conference a group of scientists and entrepreneurs (ISC was represented by Dr. Norbert Fabricius) discussed on the role of international collaboration to facilitate the industrialization of graphene and related materials. Standardization was identified as one of the most important activities to achieve this target. The results of the discussion was summarized in the “Xi’an Graphene Declaration” signed by the attendees.
