摘　　要：为了进一步提升负离子功能纤维的性能,选取Cu、CuO、Cu_(2)O和电气石(TM)为主要原料,采用分步合成和直接添加法制备新型Cu_(2)O/TM微纳结构复合材料,并测试样品的微观形貌(SEM)、物相构成(XRD)、红外光谱(FTIR)、电子自旋共振图谱(ESR)、紫外-可见漫反射光谱和负离子释放量,深入研究负离子发射的效率增强机制。研究结果表明:研磨未对电气石粉体的分子结构造成破坏;分步合成法制备的电气石复合材料性能优于直接添加法;当球磨时间控制在50 h(第1阶段)和20 h(第2阶段)时,分步合成法制备的粉体粒径分布和微观结构较好;当Cu、CuO和电气石粉末的物质的量比为1∶1.25∶2.50时,制备的复合材料负离子发射量为1647个/cm^(3),与未研磨的电气石粉末相比提高了50.1%。In order to further improve the functionality of negative-ion functional fibers,Cu,CuO,Cu_(2)O and tourmaline were selected as raw materials,a novel Cuprous Oxide/Tourmaline(Cu_(2)O/TM)micro-nano composite with excellent properties was developed by using distributed synthesis and direct addition methods respectively.The micromorphology(SEM),phase composition(XRD),infrared spectrum(FTIR),electron spin resonance(ESR),UV-VIS diffuse reflection spectrum and negative ion emission of the samples were tested to further study the efficiency enhancement mechanism of negative ion emission.The results show that the molecular structure of tourmaline powder is not damaged by grinding.The properties of tourmaline composites prepared by stepwise synthesis method are better than those by direct addition method.When the milling time is controlled at 50 h(the first stage)and 20 h(the second stage),the particle size distribution and microstructure of the powder prepared by step synthesis are better.When the molar mass ratio of Cu,CuO and tourmaline powder is 1∶1.25∶2.50,the negative ion emission of the prepared composite is 1647 ions/cm^(3),which is 50.1%higher than that of the unground tourmaline powder.
