Bacterial cellulose-based antibacterial dry film for acute trauma and preparation method and application thereof

Abstract

The invention relates to a bacterial cellulose-based antibacterial dry film for acute trauma, which comprises a bacterial cellulose-based dry film and an inorganic antibacterial agent. The drug loading quantity of the bacterial cellulose-based antibacterial dry film is 1.00*10<-5>-4.0mg / cm<2>. The preparation method of the bacterial cellulose-based antibacterial dry film comprises the following steps: cutting a bacterial cellulose-based wet film into a diaphragm; drying; then, soaking the diaphragm into an inorganic antibacterial agent solution which is prepared in advance; and drying for the second time to obtain the bacterial cellulose-based antibacterial dry film. The bacterial cellulose-based antibacterial dry film provided by the invention has the advantages of light and soft texture, good biocompatibility, high hygroscopicity, good air permeability, lasting antibacterial property and the like; and the preparation method is simple, convenient and easy to implement and is low in cost. In the practical application process, the bacterial cellulose-based antibacterial dry film can be cut into pieces in arbitrary shapes, can not adhere to the skin, can not irritate the skin, can be quickly degraded in the environment after being discarded, and can be used as an environment-friendly functional antibacterial dressing.

Description

Bacterial cellulose-based antibacterial dry film for acute trauma and its preparation and application technical field The invention belongs to the field of bacterial cellulose-based antibacterial film and its preparation method and application, in particular to a bacterial cellulose-based antibacterial dry film for acute trauma and its preparation and application. Background technique Bacterial Cellulose (BC) is a natural cellulose synthesized by microorganisms. From the chemical molecular formula, BC is no different from ordinary plant cellulose, but it has extremely high mechanical strength due to its unique physical and chemical structure. and biocompatibility. The formed BC is composed of ribbon-shaped microfibers, which are highly crystalline and highly single-oriented fibers, which are intricately entangled together to form a unique three-dimensional network structure. There are many "holes" inside the unique three-dimensional network structure of BC, which has good ...
