Porous SIBS Membranes

Dec. 2, 2022

Poly(styrene-isobutylene-styrene) block copolymer (SIBS) is a very versatile material. Due to its excellent biocompatibility, it can be applied safely even in the human body. Now the areas of biomedical applications were extended even further: it can also be used for filtering purposes, e.g., as a porous membrane acting as an active layer of a COVID mask.

In order to be able to quantitatively describe, control and fine-tune pore formation, mathematical models were developed, which also enable the modeling of the 3D structure of the membrane.
