Production of porous biomaterials (membranes, fibers, fleeces)

Regio-selectively equipped membrane for blood purification.

To build up highly porous biomaterials we use various molding and pore formation processes such as phase inversion, wet-spinning, electrospinning, freeze drying and template processes. We produce porous materials from various materials such as PLA, hydrogels, PES, PSU, PEEK and even from composite materials (PLA-HAP). On the one hand, porous biomaterials permit a good colonization with cells, as these can migrate easily in the material. On the other hand, endotoxins are selectively removed in contact with blood with the help of porous membrane fibers.
