<strong>Production</strong> <strong>Aspects</strong> <strong>of</strong> <strong>Membranes</strong><br />
Polymers / How to choose the Membrane Material?<br />
� Membrane form<strong>in</strong>g properties (mol weight distribution)<br />
� Solubility <strong>in</strong> commonly <strong>used</strong> solvents<br />
� Storage stability <strong>of</strong> the sp<strong>in</strong>n<strong>in</strong>g solution<br />
� Costs<br />
� Chemical structure with respect to<br />
�chemical stability (solvents <strong>and</strong> solutes <strong>used</strong> <strong>in</strong> the application)<br />
�physical stability (tensile strength, elongation at break)<br />
�hydrophilicity / hydrophobicity (wettability)<br />
�adsorptive properties aga<strong>in</strong>st solutes (foul<strong>in</strong>g)<br />
�extractable monomers or oligomers (TOC, toxicity)<br />
�stability aga<strong>in</strong>st oxidation (discolouration, sterilization)<br />
�stability aga<strong>in</strong>st heat / steam (temp. <strong>in</strong> application, sterilization)<br />
�bio- / hemocompatibility (prote<strong>in</strong> adsorption, cell stimulation)<br />
�make-up (w<strong>in</strong>d<strong>in</strong>g, pott<strong>in</strong>g, cutt<strong>in</strong>g, module design)
