The invention discloses a method for preparing an Ag-carrying
bacterial cellulose hydrogel
antimicrobial dressing and a product thereof. The method comprises the following steps of: soaking a
bacterial cellulose hydrogel film in solution of silver
metal precursor; then heating the film to be between 121 and 135 DEG C in a high-pressure sterilizing pot, and pressurizing between 0.205 and 0.313MPa; standing
bacterial cellulose for 5 to 30min; and then taking the treated bacterial
cellulose out for washing, partial
dehydration, packaging and sterilization to obtain an Ag-carrying bacterial
cellulose hydrogel
antimicrobial dressing which is formed by compounding silver
metal nano-particles and bacterial
cellulose and is attached with 0.01 to 10 weight percent of the silver
metal nano-particles in a bacterial cellulose three-dimensional
porous network structure. The preparation process of the invention has the advantages of simplicity, easiness, convenient operation, controllable preparation technology, no
pollution and low cost; and the prepared nano-particles have the advantages of high purity,
small particle size,
uniform size and good
dispersity. The obtained Ag-carrying bacterial cellulose hydrogel
antimicrobial dressing has the characteristics of good antimicrobial property,
high water content, good water-retaining property, strong
toughness, good air permeability and the like, and can meet the requirements of treating various wounds by a wet method.
