Makroporien

Makroporien is a term sometimes used in scientific literature, particularly in fields related to materials science and nanotechnology, to describe structures or materials characterized by very large pores. These pores are significantly larger than those found in typical mesoporous or microporous materials. The definition of "very large" can be relative to the application or the specific material system being studied, but generally, it refers to pores with dimensions on the order of nanometers to micrometers or even larger, depending on the context.

The creation and study of makroporien materials are often driven by the need for enhanced transport properties, such as increased diffusion rates for liquids or gases, or improved flow characteristics. These materials can find applications in areas like catalysis, where large pores can facilitate the diffusion of bulky reactants and products to and from active sites. They are also relevant in filtration and separation processes, where the size of the pores dictates the size of particles or molecules that can pass through.

Research into makroporien often involves developing synthesis methods that can control pore size and distribution at a macroscopic or mesoscopic scale. Techniques such as templating, phase separation, or controlled assembly of colloidal particles are commonly employed. The properties of makroporien materials are highly dependent on their pore architecture, including pore volume, pore connectivity, and surface area, all of which influence their performance in various applications. The term itself emphasizes the macro-scale dimension of the porous network, distinguishing it from other porous classifications.
