PROJECT GOAL: The proposed project seeks to understand deeply the relations among processing, structure/morphology, and mechanical properties of polymer-based nanocomposites having reinforcing clay nanolayers and carbon nanotubes. An integrated design approach based on rheology-structure-property relationship will be proposed which enable basic knowledge on the development of a spectrum of nanocomposite types. OBJECTIVES: The objectives of this work are split into following: (1) to give an overview on how the composite rheological properties are affected by nanofiller dispersion, nanofiller concentration and processing (mixing) conditions. (2) to develop a general interpretation of the rheology-structure relationship deduced to very different rheological properties and structural order around the concentrations of the flocculation and the percolation thresholds. (3) to verify the structure, morphology and cristallization behaviour of polymer nanocomposites, as affected by carbon nanotubes and nanoclay layers; (4) to relate the structural peculiarities of nanocomposites with mechanical, tribological and thermal properties enhancement. (5) to elaborate integrated approach to designing nanocomposites based on rheology-structure-property relations.
