主 题:ZnO PVC Superhydrophobicity Antibacterial WCA
摘 要:We fabricated a superhydrophobic modified ZnO/PVC nanocomposite cluster with antibacterial properties using the chemical precipitation method and selected solvent/non-solvent(THF/ethanol)to *** effects of ethanol content(47%,50%,53%,and 56%)on nanocomposite morphology and Water Contact Angles(WCAs)were *** measurements confirmed the polycrystalline structure of ZnO with a wurtzite hexagonal phase,and EDX results indicated the presence of all element *** analysis of specimens revealed a rough surface structure resembling a cluster of NPs,and that structure was dominant when the ethanol content increased to 56%.The WCA increased on the superhydrophobic nanocomposite as ethanol content increased,and an optimum WCA(160°±2°)was obtained at an ethanol content of 56%.Antibacterial activity was tested on the superhydrophobic and hydrophobic states,and the superhydrophobic specimens showed good inhibition against Klebsiella *** Staphylococcus ***,the hydrophobic specimens demonstrated no antibacterial activity against *** promising results can inform the development of nanocomposites for many environmental applications.
