Abstract
Official abstract text for this publication.
The present invention provides a method for preparing a material in the form of liquid for forming an antimicrobial surface coating with multi-level antimicrobial properties, comprising: encapsulating one or more volatile or gaseous biocides in two or more amphiphilic block copolymers to obtain a w/o/w double emulsion, and mixing the w/o/w double emulsion with one or more nonvolatile biocides, each of which is selected from the group consisting of a metal containing biocide, triclosan, a carboxylic acid, a sugar acid and a combination thereof.
First claim
Opening claim text (preview).
We claim: 1. A method for preparing a material in the form of liquid for forming an antimicrobial surface coating with multi-level antimicrobial properties, comprising: encapsulating one or more volatile or gaseous biocides in two or more amphiphilic block copolymers with different hydrophilic lipophilic balances (HLBs) to obtain a water-in-oil-in-water (w/o/w) double emulsion, and mixing the w/o/w double emulsion with one or more nonvolatile biocides, each of which is selected fro…
