Description

镱锰铜合金/腈纶电子导线的制备方法
技术领域
本发明属于可穿戴电子技术领域,涉及一种镱锰铜合金/腈纶电子导线的制备方法。
背景技术
近年来,随着科学技术的发展,特别是航空、航天技术的飞速发展,对材料的要求越来越来高,传统材料一旦制成成品,就不可能在使用过程中对其性能实施动态监控,并且材料只能被动地受环境的影响,不能针对环境的变化做出适当的反应。对于这些不足。在上世纪70年代末80年代初,受自然界生物具备的某些能力的启发,美国军方为提高行器的性能,首先提出了“可穿戴材料”的概念。分为三类:①.消极可穿戴材料,仅具有对外界环境和刺激感知的能力;②.积极可穿戴材料,具有对外界环境和刺激感知且反应的能力;③.高级可穿戴材料,不仅具有对外界环境和刺激感知和反应的能力,还表现出动态的自适应性。
腈纶是聚丙烯腈或丙烯腈含量大于85%(质量百分比)的丙烯腈共聚物制成的合成纤维。常用的第二单体为非离子型单体,如丙烯酸甲酯、甲基丙烯酸甲酯等,第三单体为离子型单体如丙烯磺酸钠和2-亚甲基-1,4-丁二酸等。聚丙烯腈纤维的性能极似羊毛,弹性较好,伸长20%时回弹率仍可保持65%,蓬松卷曲而柔软,保暖性比羊毛高15%,有合成羊毛之称。强度22.1~48.5cN/dtex,比羊毛高1~2.5倍。耐晒性能优良,露天曝晒一年,强度仅下降20%,可做成窗帘、幕布、篷布、炮衣等。腈纶在内部大分结构上很独特,呈不规则的螺旋形构象,且没有严格的结晶区,但有高序排列与低序排列之分。
用于可穿戴服装的电子导线,由于与身体长时间接触,安全问题一直存在风险,特别是含金属电子导电的应用,在人体汗液环境中,电子导线金属离子的溢出,对人体不利。本发明是在腈纶表面被覆一层镱锰铜合金层,核心工艺是在镍铝复合催化活化下,在化学镀溶液中,稀土元素镱进入锰铜合金的晶格中,形成更加致密稳定的合金层,经180天模拟人体体液腐蚀测试,镱锰铜合金/腈纶电子导线的金属离子溢出率小于百万分之一(1ppm),说明该材料具有极高的生物环境可靠性;镱锰铜合金/腈纶电子导线的电导率高于铜,达到8×107S/m以上,是目前所有导电腈纶复合材料中最好的。综上所述,本发明提出的镱锰铜合金/腈纶电子导线的制备方法具有突出的实质性特点和显著的进步,即具备创造性。

4)将活化腈纶纤维置于镱锰铜化学镀溶液中,于25℃化学镀3小时,取出洗净,烘干,得镱锰铜合金/腈纶电子导线。其中镱锰铜化学镀溶液的配方是溶剂为去离子水,溶液中各种溶质浓度分别为:硝酸镱浓度20~30g/L;硫酸铜浓度20~30g/L;硝酸锰浓度40~60g/L;碳酸氢钠浓度30~60g/L;酒石酸钠浓度60~90g/L;二甲氨基硼烷浓度3~6g/L;草酸铵浓度6~9g/L。
5)镱锰铜合金/腈纶电子导线测试表征。将镱锰铜合金/腈纶电子导线置于模拟人体体液中,于37℃放置180天,取出,以能量弥散X射线探测器(EDX)测试电子导线的元素含量,计算镱、锰、铜离子的溢出率;以四探针测试仪测试电子导线的电导率。其中模拟人体体液各成分含量:NaCl 8g/L,KCl 0.4g/L,NaHCO3 0.35g/L,CaCl2 0.14g/L,Na2HPO4 0.06g/L,KH2PO4 0.06g/L,MgSO4.7H2O 0.2g/L,葡萄糖1g/L。
