英文摘要	通过尿素分解法,把三价铬离子掺入到钇铝石榴石Y3Al5O12中,采用共沉淀法制备出绿色颜料.扫描电镜测试表明产物颗粒直径在200 nm左右,用XRD测试复合氧化物的结晶相行为,确定主相是钇铝石榴石相,用紫外可见漫反射光谱测试掺杂离子的配位状态和电子跃迁行为,用色度学测试氧化物颜色特征.将复合氧化物颜料颗粒与高分子聚丙烯共混,熔体纺丝,并通过北京同步辐射X射线CT对制得的纤维加以测试,结果表明复合氧化物颜料在高分子基质中得到良好的分散.这种颜料性能稳定,对环境友好,为实现无水印染技术奠定基础,减少纺织印染工业中所排放的污水.; The authors synthesized a new kind of green pigment via co-precipitation method by doping Y3Al5O12 with Cr3+. The size of the pigment particles is around 200 nm as observed under scanning electron microscope. XRD results demonstrate that the pigment crystalline form of the pigment is yttrium alluminium garnet. UV-Vis spectra were used to investigate the coordination states and transition behavior of the doping ions. In addition, the colour feature was measured by CIE L* a* b* chroma value. The pigment was blended with polypropylene and then polypropylene fiber was produced using the polypropelene-pigment composite via molten spinning process. The distribution of the pigment particles in the polypropylene fibers was characterized by X-ray computed tomography (CT) technique on the Beijing synchrotron radiation facility. The result states that the composite oxide pigment particles are homogeneously dispersed in the polypropylene fibers. The pigments are stable, non-toxic to the environment. and may be applied in non-aqueous dyeing to reduce waste water emitted by textile dyeing and printing industry.; 国家自然科学基金面上项目; 国家(863计划)重大项目; 科技部平台项目; 北京市教委; 北京市专利基金; 北京大学先进技术研究院培育项目; 北京市教委人才强教深化计划项目; http://gateway.webofknowledge.com/gateway/Gateway.cgi?GWVersion=2&SrcApp=PARTNER_APP&SrcAuth=LinksAMR&KeyUT=WOS:000308855500012&DestLinkType=FullRecord&DestApp=ALL_WOS&UsrCustomerID=8e1609b174ce4e31116a60747a720701 ; SCI(E); EI; 中文核心期刊要目总览(PKU); 中国科技核心期刊(ISTIC); 中国科学引文数据库(CSCD); 0; 9; 2354-2357; 32
