摘要：The invention relates to a microcapsule comprising an inorganic antimicrobialagent coated with a hydrophilic polymer. The hydrophilic polymer is able to absorbsufficient water as to enable the action of the encapsulated antimicrobial agent. Thesemicrocapsules are useful to impart antimicrobial activity and can be used in polymercompositions, sprays and coatings. A method of preparing the microcapsule bytreatment of the antimicrobial agent with a solution of the hydrophilic polymer isprovided. Another embodiment of the invention is a method of preparing the
microcapsule by coating of the antimicrobial agent with a polymer precursor followed bytreatment with a reactive ingredient. Another embodiment of the invention is a methodof preparing the microcapsule by melt compounding the antimicrobial agent with thehydrophilic polymer followed by grinding to the desired particle size. Polymercompositions comprising the microcapsules and a matrix polymer are also provided.Another embodiment of the invention is an article prepared from the polymercompositions comprising the microcapsules and a matrix polymer.
