Latest Patents

One of Okui's latest patents is a patterning method with micro-contact printing and its printed product. This method involves several steps, including applying a resin on a master with projected patterns, hardening the resin, and removing it to create a stamp. The process continues with the application of a molecular ink containing hydrophobic molecules dispersed in a solvent on the stamp. By using this stamp, micro-contact printed patterns of the hydrophobic molecular layer are formed on a substrate. The substrate is then dipped in a hydrophilic molecule solution to chemically modify the areas around the printed patterns. This innovative method results in printed products that exhibit micro-contact printed patterns at a molecular level, showcasing a distinct contrast between the patterns and the surrounding substrate.
