Abstract
In the present study, we have investigated the liquid resin composite consisted of an epoxy resin, an epoxy resin curing agent, a filler of silica particles, and a particle surface modifier of silane coupling agent at different temperatures, using atomic force microscopy and rheometry. Particular focus is on the mechanism how interaction forces between the silica surfaces and rheological properties of the liquid resin composite are affected by the silane coupling agent and the temperature. The relationship between the interparticle force and the particulate suspension rheology was discussed at a molecular level.
