摘要
Abstract
Nano-ZnO is a type of inorganic antibacterial material with low cost,high safety,and long-term stability and has received wide attention in polymer composites.The dispersion state of nano-ZnO in the polymer matrix is an impor-tant factor affecting its antibacterial performance.In this study,Zn(NO3)2 and KOH were directly precipitated in the presence of dodecyl trimethyl ammonium bromide to obtain petal-shaped ZnO nanosheets(PS-ZnO).The antibacterial performance of PS-ZnO and conventional nano-ZnO in polypropylene(PP)foams were compared.The results indicated that PS-ZnO exhibited a specific surface area of 59.6%,which is larger than that of conventional nano-ZnO due to the staggered three-dimensional microstructure,and its packing density also reached 0.23 g/cm3.PS-ZnO presented higher antibacterial efficiency than conventional nano-ZnO in the PP foams.The PP foam containing 3 wt.%PS-ZnO obtained an antibacterial rate of 99.9%against Staphylococcus aureus and Escherichia coli.This might be due to the fact that the petal-shaped structure made PS-ZnO more easily dispersed in the PP matrix,thus generating an excellent antibacterial ef-fect.关键词
