Nanomaterial Coatings

CNTs, Nanowires, Conductive Inks & Nanomaterials

Ultrasonic nozzles deposit CNTs, nanowires, conductive inks, and other nanosuspensions to form uniform, ultra‑thin functional films over complex three‑dimensional and contoured substrate geometries. Unlike conventional spraying approaches that struggle with uneven coverage on non‑flat surfaces, this deposition method delivers consistent layer thickness across raised features, recessed cavities, and curved profiles, making it well‑suited for intricate components widely used in microelectronics and advanced material manufacturing. Carefully controlled aerosol characteristics minimize material waste and reduce overspray, supporting high‑quality thin‑film formation even for delicate nanomaterial formulations.

The ultrasonic vibrations generated within the atomizer produce a natural deagglomerating effect throughout the liquid feed. Continuous mechanical energy breaks apart nanoparticle clumps that commonly build up within liquid suspensions during storage and processing, without inflicting physical damage to the underlying nanostructures. This process returns nanoparticles to their discrete, native nano‑state, preserving their intrinsic material properties. When particles remain fully separated, the final coated layers can reliably deliver the targeted electrical, optical, and mechanical performance defined by the original nanomaterial specifications.

Maintaining homogeneous particle dispersion inside the generated aerosol eliminates nozzle clogging risks and greatly improves overall coating repeatability. Stable particle distribution translates to consistent conductivity, uniform layer morphology, and predictable film‑level performance across successive production batches. Process parameters enable precise tuning over coating thickness, material loading, and solvent delivery rates, supporting diverse end‑use applications including transparent conductors, resistive heating layers, EMI shielding films, printed antennas, and functional sensor coatings. The workflow scales smoothly from laboratory‑scale benchtop research trials all the way to high‑volume, wide‑format industrial manufacturing lines.
