  • Publication number: 20190376918
    Abstract: A method for producing a nanofilm includes providing a microsieve having a first and a second opposite surface region, wherein micropores are formed between the first and second surface regions; applying a nanomaterial suspension on the first surface region of the microsieve, wherein the nanomaterial suspension comprises nanomaterial particles; and creating a pressure difference at a plurality of the micropores between the first and second surface region of the microsieve in order to move the nanomaterial suspension into the micropores and/or through the micropores, such that the nanomaterial particles adhere to the first surface region and to the wall regions of the micropores and form the nanofilm.
