With a total of 3 patents to her name, Hozumi's work is recognized for its innovative approaches to enhancing the properties of conductive materials.
Latest Patents
Hozumi's latest patents focus on the process of microcapsulating conductive metal particles with polymerized monomers. This process involves treating minute metallic particles with a coupling agent and preparing an oil phase that includes these treated particles and a reactive substance A. The reactive substance A directly contacts the metallic particles, while an aqueous phase containing a reactive substance B is prepared. This phase is capable of reacting with the reactive substance A when dissolved in water. The oil phase is then dispersed in the aqueous phase to form a suspension. An in situ reaction of the reactive substances A and B is initiated by applying heat or adding a catalyst, resulting in a thermosetting insulating resin coating on the metallic particles. Alternatively, the process can also involve immersing the metallic particles in an affinity agent and polymerizing an epoxy monomer to create an insulating polymer on their surface.
