摘      要：This article is a preliminary study on antibacterial blends of polycaprolactone,chitosan and quaternized chitosan by melt *** were characterized,mechanical test and antibacterial evaluation against Escherichia coli and Staphylococcus aureus,were *** showed that the antibacterial potential of chitosan was limited in blends and polycaprolactone/chitosan did not show significant antibacterial effect compared with neat polycaprolactone(PCL).Inhibition rates of polycaprolactone/quaternized chitosan were 39.2%99.9%against Escherichia coli,while inhibition rate was 40.9%99.9%against Staphylococcus *** quaternized chitosan(QCTS)content was up to 20%,blends exhibited 99.9%inhibition rates against both two types of bacteria.
