The Morphology And Rheological Properties Of GEP/PE In-situ Microfibrillar Blends

Properties improvement of general plastics is one of the important research fields of polymer materials science and engineering at present and in the coming long period of times. Blending and alloying have long been demonstrated to be an effective way to improve properties of an existing polymer. In the recent researches of our group, the in-situ microfibrillar reinforced composites based on the engineering plastics (GEP) and polyolefins (PO) have been fabricated by a slit die extrusion, hot stretching, and quenching process. It has been proved that the microfibrillar composites have better mechanical properties than common blends. Furthermore, the microfibrillar reinforced composites are also good potential materials for the plastic recycle. However, there is little research on the rheological behaviors of GOP/PO microfibrillar composites previously. Rheology behaviors of microfibrillar composites are necessary to investigate for the decision of processing conditions and final properties of material, because they are closely related to the morphology and micro-structure of microfibrillar composites. In this master dissertation, the microfibrillar composites, which base on the high density polyethylene (HDPE) as matrix, polycarbonate (PC), polyethylene terephthalate (PET), PET/thermoplastic elastomer HT blends as microfibrillar phase, respectively, have been successful manufactured. The rheology and morphology of them have...
