Porenwände

Porenwände, also known as pore walls, are the solid material that separates adjacent pores in a porous medium. These walls form the intricate network that defines the structure and properties of materials such as soil, ceramics, filters, and biological tissues. The thickness, shape, and connectivity of these pore walls significantly influence the overall porosity, permeability, and mechanical strength of the material. In granular materials, pore walls are essentially the surfaces of individual grains where they touch or are in close proximity. In contrast, in materials like sponges or foams, pore walls are continuous structures formed by the material itself. The surface chemistry of pore walls is also crucial, as it dictates interactions with fluids and other substances that may flow through the pores. For instance, in chromatography, the chemical properties of the pore walls of the stationary phase are responsible for separating different analytes. In geological contexts, the nature of pore walls in rocks influences groundwater flow and the storage of hydrocarbons. Understanding the characteristics of pore walls is therefore fundamental to predicting and controlling the behavior of porous materials in a wide range of scientific and engineering applications.
