The invention relates to the technical field of composite materials, and discloses an antibacterial composite fiber membrane, which in parts by weight comprises 2-3 parts of antibacterial microcapsules, 5-7 parts of tapioca starch, 1-2 parts of glycerin, 6 parts of gelatin and deionized 100 parts of water; wherein, the preparation method of antibacterial microcapsules comprises the following steps: S1. get citronella essential oil and ethyl acetate to mix and dissolve to obtain a mixed solution; S2. get β-cyclodextrin and deionized water to mix and dissolve to obtain supersaturated solution; S3. adding mixed solution to the supersaturated solution, followed by magnetic stirring, freeze-thaw and suction filtration to obtain a precipitate; S4. drying the precipitate to constant weight to obtain antibacterial microcapsules; the present invention utilizes β- The citronella essential oil is made into antibacterial microcapsules by cyclodextrin embedding method, and then tapioca starch is used as film-forming matrix, glycerol is used as plasticizer, and gelatin is used as enhancer, and the spinning solution is mixed to obtain spinning solution, which is obtained by electrospinning technology. The antibacterial composite fiber membrane achieves the effects of bacteriostasis, pest control, long action time and green safety. |
