简介：Anovelantibacterialmaterial(L-PET)waspreparedbyimmobilizingε-polylysineonpolyethyleneterephthalate(PET)nonwovenfabrics.SurfacemodificationsofthefabricwereperformedbyusingachemicalmodificationprocedurewherecarboxylgroupswerepreparedonthePETsurface,acouplingagentwasgrafted,andtheε-polylysinewasimmobilized.Scanningelectronmicroscopy(SEM)wasusedtoanalyzethesurfacemorphologyofthefabrics,whilethetoluidinebluemethodandX-rayphotoelectronspectroscopy(XPS)wereusedtoevaluatethegraftingdensities.TheantibacterialactivitiesoftheL-PETwereinvestigatedbyusingtheshaking-flaskmethod.TheelectronmicrographsshowedthatthesurfaceoftheblankPETandthemodifiedfabricsdidnotchange.TheresultsofXPSanalysisconfirmedthatε-polylysinewassuccessfullygraftedontothesurfaceofPET.TheresultsoftheantibacterialexperimentsshowedthatL-PETfabricshadexcellentantibacterialactivityagainstEscherichiacoliandStaphylococcusaureus,andthatL-PETfabricswerestableinstorageforatleasttwoyears.

简介：据报道，2015年11月3日，埃及贸工部发布终裁公告称：鉴于自中国等国家和地区进口的聚对苯二甲酸乙二脂（PET）产品的补贴、倾销与国内产业受到的损害间没有因果关系，决定终止对上述产品的反补贴反倾销调查。
