Filler-to-rubber interaction is a key parameter in reinforcement of rubber. This paper presents an investigation into the morphology of silica-reinforced Natural Rubber (NR) in presence and absence of a silane coupling agent, bis(triethoxysilylpropyl) tetrasulfide (TESPT). Improvement of the microdispersion of silica in NR with the use of TESPT is observed by Atomic Force Microscopy (AFM) imaging. Using a special network visualization technique based on Transmission Electron Microscopy (TEM), insight into the silica-torubber interaction in NR is gained. The presence of TESPT leads to strong-rubber bonding, which prevents formation of vacuoles.
