Latest Patents
Il Young Choi's latest patents include a groundbreaking invention related to high-conductivity two-dimensional polyaniline (PANI) nanosheets and the method for fabricating them. This invention involves polymerizing aniline on an ice surface, resulting in PANI nanosheets that exhibit remarkably high current flows of 5.5 mA at 1 V and an impressive electrical conductivity of 35 S/cm. These advancements represent a significant improvement over previous values reported for other PANIs in the past decades. The enhanced electrical properties are attributed to the long-range ordered edge-on π-stacking of the quinoid ring, facilitated by the ice surface-assisted vertical growth of PANI. Furthermore, the PANI nanosheets can be easily transferred onto various substrates through float-off from the ice surfaces, and they can be patterned into any shape using predetermined masks. This innovation is expected to promote the convenient and cost-effective application of conducting polymers in diverse electronic devices.
