石墨烯改性PLA复合抗菌增韧材料

石墨烯抗菌材料利用石墨烯纳米刀机制，完全破坏并阻隔细菌生长，可达到99%以上杀菌抑菌效果。研究院选用石墨烯作为活性抗菌成分，PLA原料为基材，采用自有知识产权技术分散制造工艺生产石墨烯PLA复合抗菌母粒，可应用于各种可降解材料，如一次性餐盒、保鲜膜、农用地膜、药品缓释包衣、免拆手术缝合线、人体组织修复材料等多个方向。

The graphene antibacterial material uses the graphene nanoknife mechanism to completely destroy and block the growth of bacteria, and can achieve more than 99% bactericidal and bacteriostatic effects. The research institute uses graphene as the active antibacterial ingredient, PLA raw material as the base material, and uses its own intellectual property technology dispersion manufacturing process to produce graphene PLA composite antibacterial masterbatch, which can be applied to various degradable materials, such as disposable lunch boxes, fresh-keeping Films, agricultural mulching films, drug sustained-release coatings, surgical sutures that do not need to be dismantled, human tissue repair materials, etc.
