An investigation of the properties of polyethyleneterephthalate track
membranes (PETP TMs) treated with the gaseous plasma discharge has bee
n performed. The effect of plasma of inorganic gases showed a consider
able change of the membrane surface properties. The sedimentation of t
he plasma polymerized films of organic compounds improves the physical
, chemical and medicobiological performances of the PETP TMs and exten
ds their applicability.
