How to Make a Simple Graphene Ink at Home

🧪 Want to create your own conductive ink using RGO? Here’s a simple lab-scale recipe:

✅ Ingredients:

• 50 mg reduced graphene oxide (dry or from dispersion)

• 5 mL water or isopropyl alcohol (IPA)

• 1–2 drops surfactant (e.g., Triton X-100)

• Optional: small amount of PVP or binder for coating adhesion

⚙️ Method:

1. Mix RGO and solvent in beaker.

2. Add surfactant and stir 5 min.

3. Ultrasonicate for 10 min (optional but recommended).

4. Use immediately by brush, dip, or spray.

🖨️ Use Cases

• Brush-on circuit repairs

• Low-cost EMI prototypes

• Substrate testing (plastic, paper, glass)
