1：Experimental Design and Method Selection:

The study involved preparing nanocomposite coatings using a fluoropolymer matrix (trifluorochloroethylene–vinylidene fluoride copolymer with epoxy resin) and two types of carbon nanotubes (native Taunit-MD and functionalized with alkyl groups). Methods included ultrasonic dispersion, mixing, coating application, drying, and characterization of electrical conductivity, hydrophobicity, surface roughness, and microstructure.

2：Sample Selection and Data Sources:

Samples were prepared with CNT concentrations of 9, 13, 16.5, and 20% in the fluoropolymer matrix. Data were collected from measurements of surface resistance, contact angle, sliding angle, surface roughness, and SEM imaging.

List of Experimental Equipment and Materials: Fluoropolymer matrix (trifluorochloroethylene–vinylidene fluoride copolymer), ED-22 epoxy resin, carbon nanotubes (Taunit-MD and functionalized Taunit-M), solvent, poly(ethylene terephthalate) film supports, ultrasonic bath, magnetic stirrer, atomizer, oven, van der Pauw four-electrode setup, Ecopia HMS-3000 device, KRüSS EasyDrop Standard device, bench for sliding angle measurements, Sensofar Accurion Halcyonics_micro optical profilometer, Verios 460 XHR scanning electron microscope.

4：Experimental Procedures and Operational Workflow:

CNTs were dispersed in a solvent using an ultrasonic bath, mixed with epoxy resin, then added to fluoropolymer solution. The mixture was stirred with a magnetic stirrer, applied to PET film supports using an atomizer, and dried at 60°C for 4 hours. Measurements included surface resistance (van der Pauw method), contact angle (2 μL water drop), sliding angle, surface roughness (optical profilometry), and microstructure (SEM).

5：Data Analysis Methods:

Data were analyzed to determine correlations between CNT type, concentration, and properties (electrical conductivity, hydrophobicity, surface roughness). Statistical analysis was not explicitly mentioned, but trends were discussed based on the measurements.
