A team of researchers in the US (University of Chicago, Cornell University, Argonne National Laboratory) filled a reactor halfway with liquid A, then add liquid B. At the line where the two meet, they used a tiny tube to inject the rest of the ingredients, which assembled into a film. Then scientists evaporated or drain the liquids, and the film gently glides down to rest intact. The film grows in one continuous motion, so there are no awkward joints between patches. It can be performed at room temperature. The method provides an innovative way to combine organic and inorganic layers. The different strengths and weaknesses of inorganic and organic materials could complement each other, but as the conditions to grow them are different it has been a challenge to grow them together. In tests they worked well as electrical capacitor…read more. TECHNICAL ARTICLE
Scientists discovered a new method to join thousands of organic molecules into a smooth flat film only a few nanometers thick. Credit: Baorui Cheng
