Beschreibung
Zusammenfassung:	The invention discloses a preparation method and application of a hypericin/purple phosphorus quantum dot/bacterial cellulose composite membrane, and relates to a preparation method and application of a bacterial cellulose composite membrane. The invention aims to solve the problems that the existing bacterial cellulose is limited in the field of food preservation due to no bacteriostatic activity, and a packaging material which is not easy to degrade causes serious harm to human health and environment. The method comprises the following steps: 1, preparing purple phosphorus quantum dots; 2, pretreating the bacterial cellulose membrane; and 3, compounding to obtain the hypericin/purple phosphorus quantum dot/bacterial cellulose composite membrane. The hypericin/purple phosphorus quantum dot/bacterial cellulose composite film is used for killing staphylococcus aureus. Under the photocatalytic condition, the staphylococcus aureus can be efficiently killed within 60 minutes; the prepared hypericin/purple phospho
