Systems, methods, and articles for polymer deposition

A method, comprising:

• applying a voltage and a tensile force to a filament taking the form of a wire made of a material, wherein:
• the wire is positioned in a reaction volume comprising at most 10 mTorr of air and comprising hexafluoropropylene oxide vapor;
• the reaction volume is positioned in a deposition chamber;
• the voltage causes the wire to increase in temperature;
• the wire heats the hexafluoropropylene oxide vapor, thereby causing it to decompose;
• wherein the reaction volume has a total pressure of less than or equal to 100 Torr and greater than or equal to 1 mTorr;
• wherein the temperature of the wire is greater than or equal to 150° C. and less than or equal to 1500° C.;
• and
• wherein a ratio of the applied tensile force to a rated tensile strength of the material forming the wire is greater than or equal to 0.6 and less than or equal to 0.8 at the temperature of the wire.
