Microporous material

Jump to: navigation, search

A microporous material is a material containing pores with diameters less than 2 nm.

Porous materials are classified into several kinds by their size. According to IUPAC notation (see J. Rouquerol et al., Pure & Appl. Chem, 66 (1994) 1739-1758), microporous materials have pore diameters of less than 2 nm, mesoporous materials have pore diameters between 2 nm and 50 nm and macroporous materials have pore diameters of greater than 50 nm.

Uses in laboratories

Microporous materials are often used in laboratory environments to facilitate contaminant-free exchange of gasses. Molds spores, bacteria, and other airborne contaminants will become trapped, while allowing gasses to pass through the material. This allows for a sterile environment in the contained area.

Uses in first aid

Microporous materials may also be used in first aid, commonly operating under the tradename Micropore. Micropore can be used to affix dressings to wounds, and to hold bandages in place. If necessary it can be used to cover small wounds, although it cannot be removed before the majority of the healing is completed (due to the risk of the wound reopening).
