Latest Patents

Lee's latest patents focus on high-conductivity two-dimensional polyaniline (PANI) nanosheets and the methods for fabricating them. The first patent describes a conductive two-dimensional polyaniline nanosheets template, which involves polymerizing aniline on an ice surface. The resulting PANI nanosheets exhibit remarkably high current flows of 5.5 mA at 1 V and an impressive electrical conductivity of 35 S/cm. These properties represent a significant improvement over previous values reported for other PANIs in the past decades. The enhanced electrical characteristics 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. This method also allows for the patterning of PANI into any shape using predetermined masks, which is expected to enable convenient and cost-effective applications of conducting polymers in diverse electronic devices.
