Extensional Rheology as Effective Tool for Characterization of Polymer Nanocomposites
- Conference date: 27–28 July 2011
- Location: Zlin, (Czech Republic)
Morphological characterization in polymer nanocomposites is usually performed using X‐ray scattering and microscopic techniques, while the enhancement of processing and mechanical properties is commonly investigated by rotational as well as capillary rheometry and tensile testing. However, all of these techniques are time consuming and require expensive scientific equipment. A fast and efficient way of estimating the level of reinforcement in polymer nanocomposites can be performed by melt extensional rheology, because it is possible to correlate the level of melt strength with mechanical properties, which reflect both the 3D network formed by the clay platelets/polymer chains as well as final molecular structure in the filled system. The physical network made of silicate filler and polymer matrix has been evaluated by X‐ray diffraction and transmission electron microscopy. Extensional rheometry and tensile testing have been used to measure efficiency of the compatibilizer amount in a polypropylene‐nanoclay system and to evaluate the effect of processing conditions on polymer matrix reinforcement.
