【摘要】 通过控制金属离子的浓度和反应时间制得一系列不同金属含量的双金属配合物纤维。分别对不同金属含量的单、双金属配合物的断裂强度、断裂伸长率、初始模量、回潮率等物理机械性能进行了分析。结果表明,各种配合物的断裂强度、断裂伸长率与配合物中金属含量密切相关,金属含量很低时,其值比聚丙烯腈纤维(PAN)的低,随金属含量增加可达与PAN相当值;与PAN相比,回潮率增大,初始模量减小,双金属配合物具有良好的可纺性能。更多还原

【Abstract】 A series of bimetal coordination complex fibers with different content of metal were prepared by controlling the concentration of metal ions and reaction time.Physical properties such as the breaking strength,elongation at break,initial modulus and moisture regain of the single metal and bimetal coordination complexes with different metal concentrations were tested respectively.The results indicate that the breaking strength,elongation at break are closely related to the metal concentration in coordination complexes.When the metal concentration becomes very low,their values are less than those of polyacrylonitrile(PAN).As the metal concentration increases,they are correspondent to those of PAN.Compared with PAN,the bimetal coordination complex has increased moisture regain but decreased initial modulus.The bimetal coordnation complex has good spinnability.更多还原
