NTeC™ Nanotube Hybrids Concept
• Grow Nanotubes directly on the surface of the other particles, encapsulating them with Nanotubes (“Carpet” method)
• Grow Nanotubes on metal oxide particles that are uniformly pre-mixed with the other particles prior to Nanotube synthesis (“Mesh” method)
Synthesize Nanotube Hybrids → Easy Dispersion → Enhanced Material (Mechanical, Electrical, Piezo etc..) Most Scalable, Affordable and Sustainable
NanoTube Hybrid Base Ingredient Enhanced Material

NTeC-B Nanotube Hybrid
Target Applications:
1. Conductive Additives for Battery Electrodes
2. Conductive Additives for Paints, Inks, Polymers
3. Reinforcing Additives for Tires
NTeC-B made by Mesh* method: 62% CNT / 23% Carbon Black / 15% Alumina**
*Can be made by Carpet method too.**For Battery applications, Alumina is removed via chemical purification

Experimental Results for Anode Materials
NTeC-B evaluated in commercial 18650 batteries, demonstrating:
• Much Lower internal resistance at very low Nano Tube loadings (0.5%)
• Equal performance at 50-75% lower loading (more active material = high total capacity)
• Stable long-term cycle life• Superior voltage retention at high-rate discharge (high power
for tools)• Improved charge retention at high rates (fast charge for EV)

Experimental Results for Concrete
*In Collaboration with the Center for Advanced Construction Materials, University of Texas - Arlington
• Experiments with NTeC Nanotube Hybrid with 0.1 wt% of cement *
• SUPERIOR MECHANICAL REINFORCEMENT
• Short term Strength +41%
• Compressive Strength +22%
• Flexural Strength +89%
• Young Modulus +71%
• EASY DISPERSION: Hybrid structure allows Mechanical Mixing, reproducing results of Ultra-Sonification
• SELF SENSING: Electric conductivity with piezo – electric effect enabling accurate self-sensing of stresses for performance assurance
Cost and Ease of Dispersion makes Nanotube Hybrids the only “Scalable” Nanotechnology for Cement
