Notes:
As the first step to the study of increasing biocompatibility of expanded polytetrafluoroethylene (EPTFE) membranes, cardiovascular patches of EPTFE substrates were coated with Fe3O4 layer, which is expected to accelerate proliferation of endothelial cells. The ferrite layers were formed by the thin liquid film ferrite plating method at T=75–90 °C and pH (in oxidizing solution)=6.9–7.4. At a fixed pH value, a single-phase Fe3O4 layer is obtained when T is higher than a threshold temperature, which increases with an increasing pH value; below the threshold temperature, the layer has an impurity phase of γ-FeOOH. The obtained Fe3O4 layers are polycrystalline with no preferred orientation, having magnetization and coercive force which agree with those reported for bulk samples.
