Title:
ANTIBACTERIAL ANTIVIRAL MICROCAPSULE, PREPARATION METHOD THEREFOR AND APPLICATION THEREOF
Document Type and Number:
WIPO Patent Application WO/2022/094924
Kind Code:
A1
Abstract:
An antibacterial antiviral microcapsule, a preparation method therefor and an application thereof. The antibacterial antiviral microcapsule is a composite microcapsule using antibacterial antiviral effective components as a core material, using synthetic resins as a shell material, and modified with functional chemical groups on the surface. The preparation method comprises: preparing a core material containing antibacterial antiviral effective components; using synthetic resins as a shell material to prepare a microcapsule; and modifying the surface of the prepared microcapsule.The antibacterial antiviral effective components, the synthetic resins, and the functional chemical groups are combined, and by means of a synergistic effect, long-lasting controlled release of the loaded antibacterial antiviral effective components is achieved; the prepared antibacterial antiviral microcapsule has a good attachment capacity, is wide in application range, has contact killing and anti-adhesion effects on a variety of microorganisms, and can keep the surface of an object to which the microcapsule is attached clean; moreover, the microcapsule has good biocompatibility and a long-lasting antibacterial antiviral effect, and thus, a new strategy can be provided for public health and safety protection.
