The Study of Mechanical Property of Block Copolymer Composites Tuned by Nanoscale Polymeric Morphology and Nanoparticles

The Understanding of structure-property relationships in block copolymer nanocomposites is one of the main challenges. Especially, the study of mechanical properties tuned by compositional and structural variables is significant to the applications of the nanocomposites. Here, we focus on the fundamental analysis with regard to the mechanical properties changed by the block copolymer morphologies, the volume fractions of nanoparticles and the strength of interactions between the polymeric matrix and fillers. In addition, we studied thermal annealing effects on the nanoscale structural rearrangements which link to the mechanical behavior changes.
