论文摘要
在这项工作中，制备并表征了由多碳二苯二甲酸酯制成的新型电气传导聚合物纳米复合材料，其由多壁碳纳米管和富勒烯C60制成的外体配合物制成。制剂很简单，复合物在纳米复合纤维中自组装。纳米复合材料在电刺激后由于富勒烯C60的电荷积累而显示出电气开关行为。写入读取的记忆设备是通过旋转0.8％wt的纳米复合材料来制造的。富勒烯C60到互固定的共面电极。该设备保留了超过60天以上的状态，可以热复位，对随后的电气和热循环进行重新编程和擦除。此外，可以通过应用不同的编程电压振幅和编程时间来调节设备的电阻，从而揭示其适应性行为以及对神经形态系统的潜在应用。
In this work, a novel electrospun conductive polymer nanocomposite made of polycaprolactone with an exohedral complex made of multiwalled carbon nanotubes and fullerene C60 was prepared and characterized. The preparation was straightforward and the complexes self-assembled within the nanocomposite fibers. The nanocomposite showed electrical switching behavior due to charge accumulation of fullerene C60 upon electrical stimulation. Write-once read-many memory devices were fabricated by electrospinning a nanocomposite with 0.8%wt. fullerene C60 onto interdigitated coplanar electrodes. The device retained the ON state for more than 60 days and could be thermally reset, reprogrammed and erased with subsequent electrical and thermal cycling. Moreover, the electrical resistance of the device could be modulated by applying different programming voltage amplitudes and programming times, which revealed its adaptive behavior and potential application to neuromorphic systems.
