Název v původním jazyce
Non-laminated ion-exchange membrane with improved mechanical properties
Popis výsledku v původním jazyce
Presence of reinforcing fabric noticeably increases mechanical properties of ion-exchange membranes, but at the expense of hard membrane manufacturing and higher cost. All non-laminated ion-exchange membranes have limited mechanical strength including higher dimension changes during swelling. Heterogeneous ion-exchange membranes are obviously made from LDPE which is easy processable, but this PE cannot be used for non-laminated membrane due to extreme composite brittleness. Replacing LDPE by LLDPE we were able to prepare non-laminated membranes which are more elastic, but their mechanical properties are still poor and also their using is limited. PP has generally much higher mechanical strength, higher temperature resistance and lower creep behavior in comparison to LDPE or LLDPE. Due to immiscibility of PP with PE, their blends are limited only for composites with lower filler content. For increasing PP flexibility the propylene based elastomers (PBE) are very good alternative to PP/PE blends. In this article we compare mechanical and electrochemical properties of non-laminated membranes prepared from LDPE, LLDPE, PP, PBE and blend of PP with PBE. Due to expected higher mechanical properties of PP based composites we also prepared non-laminated membranes with increased ion-exchange resin content. We confirmed that PP based non-laminated membranes have higher tensile strength even for membranes with increased resin content. Also we confirmed that with increasing of PBE content the elongation increases at the expense of decreasing modulus.
