T/CNTAC 21-2018 The method for identifying graphene materials in fibers using transmission electron microscopy
Basic Information
Scope
Scope: This standard specifies the test methods for identifying graphene materials in fibers by transmission electron microscopy, including two sample preparation methods: dissolution extraction and ultrathin sectioning. Among them, the dissolution extraction method is suitable for fibers whose main materials can be dissolved, and the ultrathin sectioning method is suitable for fibers that are easy to prepare into ultrathin sections; Main technical content: This standard specifies the test methods for identifying graphene materials in fibers by transmission electron microscopy, including two sample preparation methods: dissolution extraction and ultrathin sectioning.
