What Are Graphene Heating Films?
A graphene heating film consists of:
| Layer | Function |
|---|---|
| Graphene conductive layer | Generates heat evenly |
| Substrate (PET/PI, Cu foil, metal sheet) | Mechanical support |
| Electrodes & busbars | Uniform current distribution |
| Protective coating / insulation | Waterproofing, abrasion & corrosion protection |
Voltage can range from 3.7V → 380V AC, making graphene heaters suitable for both consumer electronics and industrial applications.
Graphene Heating Technology
Heat generation follows Joule heating:
P = I²R → fast heat with low resistance
Graphene’s sheet structure allows:
✅ Instant heat response (<1–3 seconds)
✅ Full-surface uniformity (no hotspots)
✅ High surface temperature (up to 150–300°C)
✅ Flexibility to fit curved surfaces
✅ Thin profiles: 20–80 μm
Graphene also supports integrated temperature control:
• NTC/PTC sensors
• Smart IoT heating modules
• Zonal heating patterns
