A plasma system comprising: a plasma device including; a first housing defining a first lumen, the first housing including a proximal opening and a distal opening; a second housing being in gaseous communication with the first lumen; an outer electrode having a substantially cylindrical tubular shape, the outer electrode is disposed over the first housing; and an inner electrode having a substantially cylindrical tubular shape and defining a second lumen therethrough, the inner electrode coaxially disposed within the first lumen and extending proximally past a proximal end of the second housing, the inner electrode including a proximal opening and a distal opening; the proximal opening of the first housing being disposed within the second housing, the second housing including a proximal opening and a distal opening, the inner electrode being inserted through the proximal opening of the second housing and being coupled to the second housing at that junction, the first housing being inserted through the distal opening of the second housing and being also coupled to the second housing at said junction, the second housing including an inlet; an ionizable media source coupled to the inlet of the second housing and configured to supply ionizable media thereto; a precursor source coupled to the proximal opening of the inner electrode and configured to supply at least one monomer precursor thereto; and a power source coupled to the inner and outer electrodes and configured to ignite the ionizable media at a distal opening of the first housing to form a plasma effluent at atmospheric conditions, wherein the second lumen defined through the inner electrode supplies the at least one monomer precursor into the plasma effluent such that the plasma effluent polymerizes the at least one monomer precursor to form a hydrophobic, electrically-conductive polymer. a plasma device including; a first housing defining a first lumen, the first housing including a proximal opening and a distal opening; a second housing being in gaseous communication with the first lumen; an outer electrode having a substantially cylindrical tubular shape, the outer electrode is disposed over the first housing; and an inner electrode having a substantially cylindrical tubular shape and defining a second lumen therethrough, the inner electrode coaxially disposed within the first lumen and extending proximally past a proximal end of the second housing, the inner electrode including a proximal opening and a distal opening; the proximal opening of the first housing being disposed within the second housing, the second housing including a proximal opening and a distal opening, the inner electrode being inserted through the proximal opening of the second housing and being coupled to the second housing at that junction, the first housing being inserted through the distal opening of the second housing and being also coupled to the second housing at said junction, the second housing including an inlet; an ionizable media source coupled to the inlet of the second housing and configured to supply ionizable media thereto; a first housing defining a first lumen, the first housing including a proximal opening and a distal opening; a second housing being in gaseous communication with the first lumen; an outer electrode having a substantially cylindrical tubular shape, the outer electrode is disposed over the first housing; and an inner electrode having a substantially cylindrical tubular shape and defining a second lumen therethrough, the inner electrode coaxially disposed within the first lumen and extending proximally past a proximal end of the second housing, the inner electrode including a proximal opening and a distal opening; the proximal opening of the first housing being disposed within the second housing, the second housing including a proximal opening and a distal opening, the inner electrode being inserted through the proximal opening of the second housing and being coupled to the second housing at that junction, the first housing being inserted through the distal opening of the second housing and being also coupled to the second housing at said junction, the second housing including an inlet; an ionizable media source coupled to the inlet of the second housing and configured to supply ionizable media thereto; a precursor source coupled to the proximal opening of the inner electrode and configured to supply at least one monomer precursor thereto; and a power source coupled to the inner and outer electrodes and configured to ignite the ionizable media at a distal opening of the first housing to form a plasma effluent at atmospheric conditions, wherein the second lumen defined through the inner electrode supplies the at least one monomer precursor into the plasma effluent such that the plasma effluent polymerizes the at least one monomer precursor to form a hydrophobic, electrically-conductive polymer.
