Evaluation of properties of heterogeneous ion exchange membrane according to the processing time
Original language description
This work focused on possibility of thermal degradation during preparation of heterogeneous anion exchange membranes (AEMs) by extrusion. For AEMs preparation, strong base anion exchange resin (AER) based on styrene-divinylbenzene with trimethyl ammonium functional groups was used. AER was blended with low density polyethylene (LDPE) or propylene-ethylene random copolymer (PPR) matrix using laboratory twin screw extruder. Course of extrusion during repeated homogenisation was monitored by torque and pressure. By multiple extrusions (up to 10 cycles) different processing time of anion exchange blends was obtained. AEMs were subjected to determination of ion exchange capacity (IEC), permselectivity, area and specific resistance. Only the resistance determination was able to expose the probable AER degradation. Resistance of AEMs based on PPR was independent upon the number of homogenisation cycles under chosen conditions. Contrary, AEMs based on LDPE prepared from pellets taken after 10th homogenisation cycle showed increase of area and specific resistance by 80 and 92%, respectively.
