porous structure

A porous structure is one that contains tiny holes or pores throughout its material. These pores can vary in size, shape, and distribution. The presence of pores increases the surface area and allows liquids, gases, or other substances to pass through or be absorbed into the material. Porous materials are common in nature and engineering, such as sponges, soil, or filtering filters. They are valued for their ability to trap or transmit substances, making them useful in applications like filtration, insulation, and support structures.
