Amorphous tio2 reinforced polymers for enhanced thermal and fire resistance

Overview

Loyola Marymount University presents a pioneering solution to enhance the thermal and fire resistance of polymers through the incorporation of amorphous titanium dioxide (TiO₂) nanoparticles. By using laser ablation on titanium isopropoxide, high-purity amorphous TiO₂ nanoparticles are synthesized and integrated into a polyisocyanurate (PIR) matrix via electrospinning. This results in nanofiber-infused composites with superior thermal insulation and flame-retardant capabilities. This technology is particularly advantageous for applications requiring high-performance insulation materials that meet stringent energy codes and fire safety standards.

Technical specifications

• Amorphous TiO₂ Nanoparticles: Synthesized using laser ablation, offering low thermal conductivity and excellent fire-retardant properties.
• Polyisocyanurate (PIR) Matrix: Provides a robust framework for the dispersion of TiO₂ nanoparticles, forming a stable composite.
• Electrospinning Process: Ensures uniform distribution of nanoparticles in the polymer matrix, enhancing overall material performance.
• Testing Methods: Utilizes ASTM C-177 and E84 standards for assessing thermal conductivity and fire resistance.

Technology readiness level

This technology is currently at TRL 3, indicating that it is at the experimental proof of concept stage. Future plans include further testing and optimization of the composite formulations, with validation efforts planned in collaboration with external laboratories.
