摘要： The present invention refers to a method for preparing a superhydrophobic surface on a solid substrate comprising the steps of (a) providing a solvent in the form of a pressurized fluid in a vessel, wherein the fluid exhibits a decrease in solvency power with decreasing pressure; (b) adding a hydrophobic substance to the solvent as a solute, which substance is soluble with the pressurized fluid and has the ability to crystallize/precipitate after expansion of the fluid, thereby obtaining a solution of the solvent and the solute in the vessel; (c) having at least one orifice opened on the vessel, thereby causing the pressurized solution to flow out of the vessel and depressurize in ambient air or in an expansion chamber having a lower pressure than within the vessel, the solute thereby forming particles; and (d) depositing the particles on the substrate in order to obtain a superhydrophobic surface. Hereby, a pressurized fluid which expands rapidly as a result of depressurization is used to prepare the superhydrophobic surface, thereby facilitating the preparation of the surface. Moreover, the invention refers to an arrangement for preparing a superhydrophobic surface on a substrate, a superhydrophobic film prepared by the method of the invention, and a substrate having deposited thereon the superhydrophobic firm.
摘要翻译：本发明涉及一种在固体基质上制备超疏水表面的方法，包括以下步骤：（a）在容器中提供加压流体形式的溶剂，其中流体随着压力降低而具有降低的溶解能力; （b）将溶剂中的疏水性物质作为溶质添加，所述物质可与加压流体一起溶解，并具有在流体膨胀后结晶/沉淀的能力，由此得到溶剂和溶质在容器中的溶液; （c）具有在容器上开口的至少一个孔，从而使加压溶液从容器中流出并在环境空气中或在压力低于容器内的膨胀室中减压，从而形成颗粒; 和（d）将颗粒沉积在基材上以获得超疏水表面。因此，使用由于减压而迅速膨胀的加压流体来制备超疏水表面，从而有助于表面的制备。此外，本发明涉及一种用于在基材上制备超疏水表面的装置，通过本发明的方法制备的超疏水薄膜和在其上沉积有超疏水性公司的基材。

摘要： The present invention relates to a method for the preparation of polymer shells, preferably composed of cellulose or hemicellulose, comprising the steps of dissolving the polymer component in a first solvent, preferably an organic solvent and precipitating the polymer component by contacting the first solution with a second solvent, which second solvent has a polar character, and in which second solvent the polymer component is essentially insoluble, thereby obtaining polymer shells. Moreover, the invention refers to the polymer shells as such, having permeable and responsive properties, as well as various applications comprising such polymer shells within the fields of drug delivery, separation techniques, and inter alia filling material.
