SYNTHESIS OF POLYMER NANOSTRUCTURES WITH CONDUCTANCE SWITCHING PROPERTIES

摘要

The present invention is directed to crystalline organic polymer nanoparticles comprising a conductive organic polymer, wherein the crystalline organic polymer nanoparticles have a size of from 10 nm to 200 nm and exhibits two current- voltage states: (1) a high resistance current- voltage state, and (2) a low resistance current-voltage state, wherein when a first positive threshold voltage (Vth1) or higher positive voltage, or a second negative threshold voltage (Vth2)or higher negative voltage is applied to the nanoparticle, the nanoparticle exhibits the low-resistance current-voltage state, and when a voltage less positive than the first positive threshold voltage or a voltage less negative than the second negative threshold voltage is applied to the nanoparticle, the nanoparticle exhibits the high-resistance current- voltage state. The present invention is also directed methods of manufacturing the nanoparticles using novel interfacial oxidative polymerization techniques.
