Latest Patents

Her latest patents focus on the treatment of orifice plates with self-assembled monolayers. This innovative treatment involves applying self-assembled monolayers to both the inner and outer surfaces of gold-plated orifice plates. The outer surface treatment is designed to control wettability, thereby reducing the accumulation of residual ink. The inner surface treatment enhances drop ejection, allowing for greater flexibility in controlling the steady state firing rate and uniformity of drops from the pen. Additionally, this treatment inhibits corrosion and contamination, ensuring a uniform surface for the ink. The self-assembled monolayers used in her patents include thiols, disulfides, and sulfinates, which have terminal functional groups that determine the wettability of the surface.
