|On the Use of Nanoscale Materials to Toughen Model Epoxies|
|Keywords: Nanoscale, Underfill, Epoxies|
|Epoxies are inherently brittle and are often filled or modified in order to improve fracture toughness. Recently, nanosilica has been evaluated with mixed results. We will show that the fracture toughness of nanosilica-filled epoxies is a function of nanosilica particle size. We have also examined the use of triblock copolymers to produce nanometer size rubber-particles. Such particles are also effective toughening agents for epoxies. We will compare and contrast the use of both rigid and soft nanoparticles as toughening agents for epoxies and comment on their use in underfill materials.|
