Latest Patents
One of Appel's latest patents is for a composite membrane and the process for its production. This invention involves spreading a solution of a polymer in a volatile organic solvent on water, allowing the solvent to evaporate, and then crosslinking the polymer to form a film that is transferred to a porous support membrane. The polymer used is preferably a polysiloxane, which is cross-linked via polymer-bonded OH groups. This composite membrane is particularly suitable for applications such as pervaporation.
Another significant patent by Appel is focused on a process and device for producing ultrathin layers and layer elements. This invention describes a method for continuously producing an ultrathin, ordered layer of amphiphilic molecules on the surface of a polar liquid. The process involves creating a directed flow of the polar liquid in a duct, where amphiphilic molecules are present. The design includes sections with varying flow rates to facilitate the formation of the ordered layer at the polar liquid/air interface.
