Extensional and shear rheology as a powerful tool for characterisation of physical networks in polymer nanocomposites

Description

Polymer nanocomposites are an interesting class of materials, in particular in the field of light weight construction. With increasing knowledge about proper processing protocol and resulting nanocomposite structure and property profile, respectively, it is possible to utilize polymer nanocomposites in many applications like automotive or aerospace industry. During material development procedure, rheological investigation possesses crucial information about material structure/performance already in the processing stage. Therefore, right compilation and interpretation of rheological measurements can significantly speed up the developing procedure. In this contribution, selected polymer nanocomposites have been characterized by both extensional as well as shear rheology. Using novel evaluation of oscillatory shear flow data, it was possible to correlate data of shear rheometry with those of elongational rheometry and, consequently, to obtain complex rheological information about different physical networks of nanopartikel in polymer matrix.
