Co to jest Inżynier Are Porous Materials?

Inżynier porous materials are synthetic or modified natural substances characterized by a highly controlled, three-dimensional network of pores. Unlike conventional filter media, their pore size, shape, distribution, and surface functionality are precisely designed to target specific contaminants. These materials can be derived frem activated carbon, polimers, ceramics, metals, or conterine frameworks.
