【摘要】 由于聚乙烯醇纤维大分子中的—OH含有孤对电子对,可与金属离子发生配位反应。为了制备PVA-Fe(Ⅲ)配合物纤维,并分析其性能特征,首先对聚乙烯醇纤维进行了初步处理,然后使其与Fe(Ⅲ)反应,从而制得PVA-Fe(Ⅲ)配合物纤维。测试了PVA-Fe(Ⅲ)配合物纤维的力学性能、吸湿性能以及电学性能,PVA-Fe(Ⅲ)配合物功能纤维与原PVA纤维相比具有较大差异,通过控制金属离子含量,可提高纤维断裂强度和体积比电阻。更多还原

【Abstract】 For lone electron pair in —OH of polyvinyl alcohol fiber, reaction to metal ion can be done.To prepare PVA-Fe(Ⅲ) coordination fiber and analyzed its property,treatment of polyvinyl alcohol fiber was done,reaction to PVA-Fe(Ⅲ) was done too,PVA-Fe(Ⅲ) coordination was got.Mechanical property,moisture adsorption,electricity property of PVA-Fe(Ⅲ) coordination fiber was tested.PVA-Fe(Ⅲ) coordination functional fiber has more difference to PVA fiber,breaking strength and volume resistivity can be enhanced by control metal ion content.更多还原
