Abstract: The present invention relates to a new method of synthesizing two-dimensional polyaniline (PANI) nanosheets using ice as a removable hard template. The method comprises polymerizing aniline on an ice surface. The synthesized PANI nanosheets show distinctly high current flows of 5.5 mA at 1 V and a high electrical conductivity of 35 S/cm, which mark a significant improvement over previous values on other PANIs reported over the past decades. These improved electrical properties of the PANI nanosheets are attributed to the long-range ordered edge-on π-stacking of the quinoid ring, ascribed to the ice surface-assisted vertical growth of PANI. The PANI nanosheet can be easily transferred onto various types of substrates via float-off from the ice surfaces. In addition, PANI can be patterned into any shape using predetermined masks, and this is expected to facilitate the eventual convenient and inexpensive application of conducting polymers in versatile electronic device forms.

The PANI nanosheet can be easily transferred onto various types of substrates via float-off from the ice surfaces. In addition, PANI can be patterned into any shape using predetermined masks, and this is expected to facilitate the eventual convenient and inexpensive application of conducting polymers in versatile electronic device forms.

Abstract translation: 本发明涉及使用冰作为可去除的硬模板合成二维聚苯胺（PANI）纳米片的新方法。 该方法包括在冰表面上聚合苯胺。 合成的PANI纳米片在1 V时显示5.5 mA的明显高电流，35 S / cm的高电导率，这显着超过了过去几十年来报道的其他PANI值的显着改善。 PANI纳米片的这些改进的电性能归因于醌型环的长程有序边缘π堆叠，归因于PANI的冰表面辅助垂直生长。 PANI纳米片可以通过从冰表面浮起而容易地转移到各种类型的基底上。 此外，PANI可以使用预定的掩模图案化成任何形状，并且预期将促进导电聚合物在多功能电子设备形式中的最终方便和便宜的应用。
