Controlling reaction temperature for a set time enables the size of gold nanoparticles autoreduced on the surface of polyaniline nanofibers to be controlled. The size of the gold nanoparticles can be used to tune the electrical bistable memory effect in gold/polyaniline nanofiber composite devices. Turn-on voltages and on/off ratios improve with decreasing nanoparticle size, making this a promising method to enhance performance and create smaller devices. Long-term stability of the composites can be improved by the addition of stabilizers following autoreduction of the gold nanoparticles.
控制反应温度和时间可以控制金纳米粒子在聚苯胺纳米纤维表面的自还原尺寸。金纳米粒子的尺寸可以用于调整金/聚苯胺纳米纤维复合器件的双稳电记忆效应。随着纳米粒子尺寸的减小，开启电压和开/关比提高，这是一种提高性能和制造更小器件的很有前途的方法。通过在金纳米粒子自还原后添加稳定剂，可以提高复合材料的长期稳定性。
