Conductive Polymer Dispersion Technology


AnCatt provides Conductive Polymer Nanoparticle Dispersion Technology. Our conducting polymer nanocomposites (see Figure 1 below ) are easy to be processed. They are extrudable (see Figure 2), and they are soluable in many organic solvents such as ethanol (see figure 3). The dispersed conductive polymer particles are in consistent spindle shapes proximately 100 nm long and 50 nm wide (see figure 4). Conductive polymer could be switched between a conducting state and a non-conducting state.

Our nanoparticle dispersion technology enables large-scale commercialization of conductive polymer (also know as conductive plastic) applications that have long been anticipated, such as anti-corrosion primers, electrostatic dissipation coatings, electromagnetic interference shielding, static resistant fibers, conductive inks, conductive toners, conductive adhesives, conductive textiles, etc.

Our innovative Environmentally Friendly Heavy-Duty Anti-Corrosion Coating Technologies have successfully utilized this dispersion in corrosion protections, and our coatings have withstood over 13,000 hours of Salt Fog Exposure (ASTM B 117) tests with no appearance of rust or blister.

The high loading CPND approach shows promise not only for corrosion-resistance, but also as a technology readily incorporated in a wide variety of coating types. The easy-to-process, organic, high-performance, light-weight, low-cost, flexible, transparent, color-changing, conductive CPND nano-scale material should enable other large-scale commercialization of conductive polymer applications. Organic options will soon go from grocery stores to electronic and industrial applications such as Organic Light Emitting Diodes (OLEDs) for lightings, organic TV/personal electronic displays, organic sensors, etc.
