摘　　要：为研究纳米银与海藻酸钠间的相互作用,采用预添加、后添加两种方法制备纳米银/海藻酸钠导电体系。测试分析了不同制备方法海藻酸钠对纳米银性质的影响,并在改性棉织物上进行涂层。结果表明:预添加海藻酸钠对纳米银的合成产生显著影响,当海藻酸钠浓度超过0.3%,纳米银发生显著团聚,其尺寸增大;后添加海藻酸钠对合成纳米银的性质不会产生明显影响。随着阳离子试剂EPTAC浓度的增加,改性棉织物的亲水性增加,同时纳米银/海藻酸钠导电涂层的导电性提高,渗化度略有升高。In order to study interaction between nano-silver and sodium alginate,nano-silver/sodium alginate conductive system was prepared by pre-adding method and post-adding method.Effects of different preparation methods on properties of silver nanoparticles were tested,the modified cotton fabric was coated.The results showed that the pre-adding sodium alginate had a significant effect on the synthesis of silver nanoparticles.When the concentration of sodium alginate exceeded 0.3%,silver nanoparticles agglomerated significantly and their sizes were increased.The post-adding of sodium alginate would not significantly affect properties of the synthesized silver nanoparticles.With the increase of the cationic reagent EPTAC concentration,hydrophilicity of the modified cotton fabric and conductivity of the nano-silver/sodium alginate conductive coating were increased,and the permeability was increased slightly.
