Preparation method of flexible conductive antibacterial polylactic acid composite nanometer fiber film

The invention discloses a preparation method of a flexible conductive antibacterial polylactic acid composite nanometer fiber film. The method is characterized in that 80-95% of polylactic acid, 1-10%of graphene and 1-10% of nano silver by mass are included, after oxidation of graphene, an oxidized graphene dispersion liquid is prepared, the polylactic acid and nano silver are added to the oxidized graphene dispersion liquid and stirred till the polylactic acid is dissolved, a reducing agent is added to reduce the graphene, a solution for static spinning is prepared, and the film is preparedthe fibers obtained by static spinning. The prepared flexible conductive antibacterial polylactic acid composite nanometer fiber film is high in tensile strength and antibacterial, flexibility and conducting performance, and can be used for conducting paper, an electronic fabric, a flexible circuit, a flexible sensor and the like. 本发明公开了种柔性导电抗菌聚乳酸复合纳米纤维膜的制备方法，其特征是，以质量百分比计，包括聚乳酸80-95%，石墨烯1-10%以及纳米银1-10%，将石墨烯氧化后，制备氧化石墨烯分散液，将
