Title: Inventor Spotlight: Donald J Lennon
Introduction
Donald J Lennon, hailing from Acton, MA, has made significant contributions to the world of technology and innovation, securing a total of 8 patents throughout his career. His work primarily focuses on enhancing materials for electrostatic imaging surfaces, showcasing a deep understanding of chemistry and material properties.
Latest Patents
One of his latest patents includes an innovative approach to anodized electrostatic imaging surfaces. This technology involves the dielectric sealing of porous anodized aluminum. In this process, moisture trapped in the pores of the hardcoat anodizing coating is meticulously removed. Subsequently, the porous surface is impregnated with a water-insoluble metallic salt, utilizing a compound from Group II or III metals fused with a long-chain fatty acid that contains between 8 and 32 carbon atoms, whether saturated or unsaturated. The application of this impregnant material can be conducted either as a hot melt or in a solution, with any excess promptly removed from the surface. The final product demonstrates excellent resistivity and dielectric properties, which remain stable even under elevated humidity conditions. Additionally, the surface may undergo polishing to enhance toner release characteristics during pressure transfer, reinforcing the practical applications of Lennon’s invention.
