1：Experimental Design and Method Selection:

The study used the polyol solvothermal method to synthesize silver nanowires and prepared aqueous conductive inks with polyaniline, guar gum, and hydrochloric acid. Screen printing was employed to coat the inks onto cotton fabric substrates, with variations in ink amount, coating layers, and heat treatment temperature to study their effects on microstructure and electrical properties.

2：Sample Selection and Data Sources:

Cotton fabric substrates (3 × 3 cm2) were used. Silver nanowires were synthesized with specific dimensions (60–100 nm diameter, 8–15 μm length). Data on electrical properties were collected using a four-point probe method.

3：List of Experimental Equipment and Materials:

Materials included silver nitrate, poly(vinylpyrrolidone), ferric chloride hexahydrate, ethylene glycol, ethanol, aniline, hydrochloric acid, ammonium persulfate, nitric acid, and guar gum. Equipment included a scanning electron microscope (Zeiss MERLIN VP Compact, JSM-6460), four-point probe instrument (ST2253), X-ray diffractometer (DIFFRRACTOMETER, Rigaku Co.), and a hot plate for heat treatment.

4：Experimental Procedures and Operational Workflow:

Silver nanowires were synthesized, inks were prepared by mixing components and stirring, then printed onto fabric using screen printing (200/inch nylon wire mesh, scraper angle 75°). Samples were heat-treated at various temperatures, and multiple layers were applied with drying intervals. Microstructure was examined with SEM, and sheet resistance was measured at multiple points.

5：Data Analysis Methods:

Sheet resistance was measured using a four-point probe, with mean values calculated from 8 points per sample. XRD was used for phase structure analysis, and SEM for morphological observation.
