Reinforcing nanoparticles in reactive resins

A novel route to prepare nanocomposites consisting of monodispersed SIO 2 -nanoparticles and reactive resins was developed followed by an intensive study of mechanical properties of various epoxy-resin/ SIO 2 -nanoparticle systems. This new innovative technology leads to materials combining increased modulus with a significant improvement in fracture toughness and processability. Even with very high loads of nanosized particles, water-clear systems can be realized with lower viscosities than filled systems based on conventional particle reinforcing strategies.
