SEM image of a fracture surface of a Matrimid® MMM with (a) 8 vol % AC and (b) 50 vol % AC. The increased concentration of the AC particles at the bottom of the membrane due to the membrane preparation is visible. The “crater”-like morphology is observed in the case of the 8 vol % AC while it is not visible for the 50 vol % AC due to the high content of fillers.
