Antibacterial film layer with waterproof and anti-fingerprint functions

The invention relates to the technical field of films, in particular to an antibacterial film layer with waterproof and anti-fingerprint functions. The antibacterial film layer comprises at least onesubstrate layer and antibacterial layers which are sequentially arranged from bottom to top, wherein the thickness of the base material layer is 1-300 nm; the antibacterial layers are composed of an antibacterial layer A and an antibacterial layer B; the antibacterial layer A is an organic antibacterial agent which is mainly vanillin or an ethyl vanillin compound, and the covering thickness of theantibacterial layer A is 1-300 nm; and the antibacterial film layer B is made of a silane-modified perfluoropolyether compound, and the covering thickness the antibacterial film layer B is 1-300 nm.The antibacterial film layer can play an antibacterial role and has very high hydrophobicity. 本发明涉及膜技术领域，具体是一种带防水防指纹功能的抗菌膜层，包括至少一个基材层和抗菌层，依次从下至上设置，基材层厚度为1-300纳米,其中抗菌层设有抗菌A层和抗菌B层，抗菌A层为有机抗菌剂，主要为香草醛或乙基香草醛类化合物，覆盖厚度为1-300纳米，抗菌B层为矽氧烷
