Coefficient of thermal expansion of TiO2 filled EVA based nanocomposites. A new insight about the influence of filler particle size in composites

- A method based on the use of AFM was proposed to measure CTE of thin films.
- The effect the presence of TiO2 nanoparticles on the CTE of EVA was evaluated.
- New theoretical model proposed to understand the influence of the filler on the CTE of composites.
- Interphase and size of particles in composites are the main factors to change polymer matrix CTE.
