Description

一种纤维状电化学发光电池及其制备方法
技术领域
本发明属于电化学发光电池技术领域，具体一种涉及纤维状电化学发光电池及其制备方法。
背景技术
自从1991年日本Iijima首次发现碳纳米管以来，碳纳米管以其独特的力学、电学、热学等性能受到人们广泛的重视，具有良好的发展前景，必将成为新一代热门材料。
碳纳米管是可以根据石墨片层的数目分为单壁碳纳米管和多壁碳纳米管。独特的碳纳米管结构赋予了其优异的力学、电学性能, 如杨氏模量高达1000吉帕(约为钢的5倍),拉伸强度高达63吉帕(约为钢的50倍). 由于碳纳米管较低的密度(约为钢的1/6)、较高的强度、较高的电导率以及其他优异的物理性能, 碳纳米管被认为在结构材料、电子器件、场发射、生物医药和电化学等广泛领域有着巨大的应用前景。同时，碳纳米管被广泛应用于发光器件、聚合物太阳能电池和超级电容器等领域。
随着现代电子事业的发展需要，柔性发光器件变得越来越重要。如采用柔性基底的有机发光二极管和电化学发光电池等，形成可以柔性发光器件[1-20,24]。然而这些柔性发光器件不能满足轻质、小巧和可编织的发展要求。
未来的发展要求是微型器件具有发光或者显示功能，目前尚没有文献报道纤维状电化学发光电池。制作纤维状电化学发光电池的主要难关在于其良好的界面接触，以及寻找合适的透明柔性电极。如果能够解决上述问题，纤维状电化学发光电池在未来的发展中会具有非常好的前景。在不久的将来，将纤维状电化学发光电池将具有非常重要的意义。
发明内容
本发明的目的在于提供一种发光效率高、成本低的纤维状电化学发光电池及其制备方法。
本发明提供的纤维状电化学发光电池，包括：一金属丝，作为纤维基底电极，该金属丝表面修饰有氧化锌纳米粒子，作为电子传输层；一发光聚合物层，沾涂在氧化锌纳米粒子修饰的金属丝表面；一透明电极，由多壁取向碳纳米管薄膜以同轴缠绕在沾涂了发光聚合物层的金属丝基底上组成。其结构示意图图1所示。
由于多壁取向碳纳米管薄膜具有良好的透明性和导电性，作为透明电极，使纤维状电化学发光电池的发光的效率大大提高，而成本却大大的降低。
本发明还提出了纤维状电化学发光电池的制备方法，具体步骤如下：
（1）制备透明电极材料：在多壁可纺碳纳米管阵列上拉出多壁取向碳纳米管薄膜；
（2）制备纤维状金属丝基底：将金属丝沾涂氧化锌溶液，再退火，退火温度为300-600摄氏度，退火时间为0.5-2小时，在金属丝表面形成氧化锌纳米粒子层；该步骤重复多次，使氧化锌纳米粒子层具有适当厚度，一般厚度20-100纳米，从而得到氧化锌纳米粒子作为电子传输层修饰的金属丝；所述金属丝如钢丝、钛丝或铝丝等；
（3）然后，在氧化锌纳米粒子修饰的金属丝表面沾涂一层发光聚合物层，并在真空环境中放置1-10小时；将多壁取向碳纳米管薄膜均匀的缠绕在其上面作为透明电极，得到完整的线状发光器件；
（4）最后，将得到的纤维状电化学发光电池在干燥的惰性气体环境下采用密封性较好的高分子材料封装。
本发明中，所述发光聚合物层材料可为聚芴或SuperYellow等不同颜色发光聚合物。
下面是制备纤维状电化学发光电池的具体操作步骤：
首先，通过沾涂法在金属丝（如不锈钢丝）表面形成氧化锌纳米粒子层，然后在管式炉中300摄氏度下煅烧30分钟并退火，待温度降到室温以后取出。将此过程重复3次在金属丝表面形成一定厚度的氧化锌纳米粒子层作为电子传输层，放入充满氩气的手套箱中；在充满氩气的手套箱中将氧化锌纳米粒子修饰的不锈钢丝用于制作纤维状电化学发光电池。通过沾涂发光聚芴的一种衍生物PF-B（20-60 mg/mL），乙氧基化三羟甲基丙烷三丙烯酸酯和三氟甲基磺酸锂的四氢呋喃溶液，然后抽真空一小时；将多壁取向碳纳米管薄膜均匀的缠绕在金属丝上面，最终形成完整的纤维状电化学发光电池。最后，采用封装材料将器件在干燥的惰性气体环境中封装起来，得到完整的纤维状聚合物发光电池。
所述取向碳纳米管薄膜中使用的碳纳米管阵列采用常规技术制备，具体步骤为：
合成碳纳米管阵列的催化剂结构为Si/SiO2/Al2O3/Fe，其中，SiO2厚度为300-1000μm，Al2O3厚度为1-30 nm，Fe厚度为0.5-1.5 nm，Al2O3位于硅片和Fe的中间，作为缓冲层，Fe作为催化剂，它们分别通过电子束蒸发镀膜仪在硅片上沉积一层纳米厚度的膜；采用化学气相沉积法，用乙烯做碳源，以氩气和氢气作为载气，在有氧化层Si基片上合成高度取向的碳纳米管阵列；其中乙烯流量为190-290 sccm，氩气流量为400-620 sccm，氢气流量为20-48 sccm，在管式炉中生长5-20 min。
本发明制备的纤维状电化学发光电池，能够有效的实现360度发光，并且具有很好的柔性以及可编织性能。同轴结构对于器件的发光具有非常明显的优势。对于发光器件来说，在径向方向上相似于平面状发光器件，大大的降低了接触电阻，同轴结构具有高的接触面积，有利于电子的快速传递和转移；同时采用多壁碳纳米管薄膜作为透明电极，大大的改善了器件的发光效率，具有广阔的发展前景。多壁碳纳米管薄膜是通过将化学气相沉积法合成的多壁可纺碳纳米管阵列进行干法纺丝得到的[21-23]。电化学发光电池的机理是当器件两端受到足够的电压，电致发光共轭聚合物两端发生化学掺杂，在靠近阴极的一端发生N型掺杂，在靠近阳极的一端发生P型掺杂。由于掺杂，聚合物层具有较高的电导率。形成PIN结，有利于电子和空穴在两端的有效注入，最终电子和空穴发生复合，产生光。在未来，纤维状电化学发光电池在光电子织物技术领域具有广阔的发展前景。本发明在实验中采用的氧化锌前驱体溶液是1.46 g 的Zn(CH3COO)2• 2H2O 和 0.2 mL的 NH2CH2CH2OH 溶解于25 mL CH3OCH2CH2OH 中，并在60度条件下搅拌30分钟。
