摘要
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 n-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.
