Surface Modification of Electrospun PVDF/PAN Nanofibrous Layers by Low Vacuum Plasma Treatment

Figure 4

Diagram of the low-pressure vacuum MF plasma apparatus. The selected gases from the gas cylinders (A), connected to a mass flow controller (B), are controlling defined amount of gases to low-pressure vacuum plasma chamber (C) which is bound up with a vacuum pump (D). Defined work atmosphere is energized by MW (microwave) plasma head (E) which is powered by MW generator (F).
