▎ 摘　　要

NOVELTY - Antistatic polyglycolic acid composition comprises 100 pts. wt. polyglycolic acid, 0.01-10 pts. wt. antistatic agent, preferably 0.1-1 pts. wt. The antistatic agent is edge-modified graphene and the edge-modified graphene has the following characteristics: the average sheet diameter is 2-30 μm, preferably 5-15 μm, have an average aspect ratio of 600-10,000:1, preferably 1500-3800:1, have a conductivity of 200-800 S/m, preferably 300-600 S/m. In the edge-modified graphene, the oxygen content in terms of oxygen element is 3-30 (at)%, preferably 5-18 at%. The hydrogen content in terms of hydrogen element is 1-10 at%, preferably 3-8 at%. USE - The composition and material are useful in the field of electronic packaging material (claimed). ADVANTAGE - The composition: has good mechanical property and antistatic property; can be naturally degraded; greatly improves mechanical property e.g. tensile strength and impact strength, which is of great significance for practical production and application; has non-cross-linked structure; can be degraded in a neutral environment; does not cause secondary pollution to the formation and meets the requirements of circular economy. The method: is environmentally-friendly, simple process and economical; has short reaction cycle and prepares edge carboxylated graphene has good sheet integrity. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: antistatic polyglycolic acid complex material, which is prepared by antistatic polyglycolic acid composition; and preparing antistatic polyglycolic acid complex material comprising mixing the components of the antistatic polyglycolic acid composition, melting and mixing, extruding and granulating to obtain the antistatic polyglycolic acid complex material.
