Abstract: Problems such as mechanical irritation of the face and microbial bacterial growth caused by prolonged wearing of masks, resulting in facial discomfort, need to be urgently solved. In this study, a polyacrylic acid (PAA)-sodium alginate (SA) microencapsulated composite hydrogel reinforced by bacterial cellulose (BC) was designed. Sodium alginate-coated lemon essential oil microcapsules (LEO@SA) were prepared using the microencapsulation technology method, and the hydrogen bonding cross-linking of BC with PAA was utilized to construct a three-dimensional hydrogel network structure. SEM and XPS analyses confirmed that the microcapsules were homogeneously dispersed in the hydrogel, and the introduction of BC enabled the material to exhibit excellent tensile strength of 0.06 MPa and elongation at break of 72.56%. The hydrogel showed excellent bacteriostatic effect against both Staphylococcus aureus (S. aureus) and Escherichia coli (E. coli) within 24 hours. And the inhibition rate of the material against S. aureus was more than 98% at pH 4.5 close to the skin of human face. he human skin adherence experiments showed that the hydrogel had good adhesive properties, which not only ensured the close fit between the hydrogel and the skin, but also effectively blocked the invasion of some bacterial microorganisms, and did not cause red marks on the skin after 8 hours of continuous wear. This study provides a reference for the development of new medical mask dressing.
