1：Experimental Design and Method Selection:

The study involved open-air plasma treatment of PTFE at atmospheric pressure using Ar, Ar + O2, and Ar + H2 gases to modify the PTFE surface for improved adhesion with Ag ink.

2：Sample Selection and Data Sources:

PTFE sheets were used as samples, cleaned with acetone and pure water, and dried before plasma treatment.

3：List of Experimental Equipment and Materials:

Equipment included an open-air plasma treatment system, multichannel spectrometer, spin coater, ceramic heater, peel tester, and various analytical instruments like XPS, AFM, ESR, and water contact angle tester.

4：Experimental Procedures and Operational Workflow:

The process included plasma irradiation, exposure to air, coating with Ag ink, and heating to form an Ag film. Adhesion strength was measured using a peel test.

5：Data Analysis Methods:

Data were analyzed using XPS for chemical composition, AFM for surface morphology, ESR for radical density, and water contact angle measurements for wettability.
