In April 2021, China Chemical Fiber Industry Association entrusted an international authoritative testing organization to take random samples at the site of gaoene technology, through a series of procedures such as sealing, sample delivery and testing. In August, a formal conclusion was reached:

It is verified by AFM method that the thickness of Monolayer Graphene Oxide  of Gaoxi Tech is 1.1nm, which is consistent with the theoretical value of Monolayer Graphene Oxide!

So far, the Graphene Multifunctional Composite Fiber has passed the dual certification of China Chemical Fiber Industry Association and International Graphene Product Certification Center (IGCC)
