Abstract  

十大靠谱网赌appMicrophase separation in multiphase polymers endows the materials with excellent comprehensive physical and chemical properties. In particular, the nanoscale interphase and interfacial interactions between different phases play a key role in controlling the final property of the material, while the molecular level detection of the interphase remains a great challenge. Elucidation of the microdomain structure and interphase is important for the design and preparation of high-performance polymer materials. In this talk, taking the elastomer toughened thermoplastic polymers and thermoset/block copolymer blends as examples, I will introduce the multiscale solid-state NMR studies on the microdomain structure, interphase and interfacial interactions in these multiphase polymers, and thus to elucidate the evolution of microphase separation and mechanism of the toughening, and provide theoretical and experimental guidance for the design of novel high-performance multiphase polymers.
