OCSiAl Graphene Nanotubes Offer Transparent Conductive Coatings for 3C Products

Films play an important role in the consumer electronics sector, protecting smartphones, tablets, and laptops from scratches, fingerprints, and dust. As demand for such gadgets grows, so does the need for functional and visually attractive protective coatings, with a worldwide market growth rate of 5.33% expected by 2027. Graphene nanotubes provide a one-of-a-kind option for coatings for 3C goods that combine permanent conductivity and excellent transparency without requiring changes to ordinary technical processes and equipment.

Graphene nanotubes, a new generation anti-static agent, form a 3D conductive reinforcement network inside the material at ultralow concentrations of about 0.04 wt.%. Because of this low concentration, nanotubes retain up to 80% product transparency and a haze value of less than 6%. This is due to the peculiar shape of graphene nanotubes. Graphene nanotubes have a high length-to-diameter ratio, vast surface area, outstanding conductive and thermal characteristics, and high strength, resulting in stable, permanent electrical resistance of 10^4-10^9 Ω/sq inside the material. This gives the film an anti-dust effect and makes it compatible with touch-screens.

According to Vilson Jiang, Sales Manager for Coatings and Composites at OCSiAl China, "Transparent conductive films manufactured with graphene nanotubes can even be applied without a primer, simplifying the production process and increasing the cost efficiency of the final product."

Aside from film coatings, graphene nanotubes are frequently used in various kinds of polymer coatings, including ESD floors, conductive primers, anti-static powder coatings, tank lining coatings, and so on. Currently, OCSiAl and its OEM partners manufacture graphene nanotube coating solutions throughout Europe and Asia.
