Technology & Patents

Building on research at the Organic Semiconductor Materials & Devices Lab, Pukyong National University, we synthesize and formulate conductive polymers and hybrid materials in-house.

Core technology

PEDOT:PSS synthesis & formulationBuilding on our conductive polymer synthesis and thin-film fabrication technology, we make water-based PEDOT:PSS grades with work function (5.3 eV to above 5.7 eV), conductivity and stretchability tuned to each application. → High-φ PEDOT:PSS, AH-PTE
Polymer/nano-metal hybridsHybrid solutions that combine polymers and nanomaterials to build flexible, stretchable transparent electrodes, sensors, heaters and EMI-shielding films. → AH-PNW, Surface modifiers
Stretchable, recyclable conductive materialsA composite of a cellulose network interwoven with PEDOT:PSS: less than 2.6 % degree of hysteresis at 50 % strain, ~190 % stretchability, and it can be dissolved and recycled. → AH-CEPT
Charge injection & electrolyte materialsLow-work-function electron injection layers (3.96 / 4.1 eV) for organic and flexible devices, and ion gel electrolytes (~1.16 mS/cm) for electrochromic devices. → AH-EIM, EC-GEL1
