The analyses suggested the presence of a separated phase for the films with enhanced tensile strength by bimodal tanδ curves. However, bimodal tanδ curves alone could not define phase separation status. In this work, AFM was applied in order to confirm the detail about phase separation of soft coating films for optical fibre. As a result, we found that AFM was suitable for visualisation of the morphologies of phase separate films with low Young’s modulus. As a next step, we are going to examine the Run2 film and elucidate the mechanism that Run2 film had similar mechanical strength as Run5 film in spite of lower Young’s modulus. n dynamic mechanical
