Abstract
A method of manufacturing a coated metallic wire having a polymeric coating, the method includes: dissolving at least one polymer including a poly(aryl etherketone) in at least one phenolic solvent to form a solution; contacting the surface of a metallic wire with the solution to form a coated wire having at least one layer of coating; and drying the coated wire to evaporate residual solvent.
Claims28
A method of manufacturing a coated wire, the method comprising:
- dissolving at least one polymer comprising a poly(aryl etherketone) in at least one phenolic solvent to form a solution;
- contacting the surface of a wire with the solution to form a coated wire having at least one layer of coating;
- and
- drying the coated wire to evaporate at least about 80 wt % of the solvent, such that the residual solvent after drying is about 20% or less.
- optionally, repeating contacting and drying.
A coated wire having a core and at least one layer of coating comprising a poly(aryl ketone), wherein the coated wire is formed by a process of:
- dissolving at least one polymer comprising a poly(aryl etherketone) in at least one phenolic solvent to form a solution;
- contacting the surface of a wire with the solution to form a coated wire having at least one layer of coating;
- and
- drying the coated wire to evaporate residual solvent.
A coated wire comprising:
- a metallic core of at least 20 wt. % metal;
- at least one layer of coating surrounding the metallic core, the coating comprising a poly(aryl etherketone);
- and
- at least 5 ppm to 5000 ppm of a phenolic solvent.
