Rheological and spinning properties of polystyrene/nano aluminum composites
摘要
Abstract
PS/AlNPs composite fibers were prepared by adding AlNPs into PS to finish the simulation study of conductive matrix materials for Z-pinch:deuterated polystyrene/nano-aluminum (DPS/AlNPs).The effects of temperature and shear rate on the rheological properties,the relationship between the structural changes,the flow condition of composites melt and the proper-ties of PS/AlNPs,as well as the morphology,thermal stability and mechanical properties of PS/AlNPs fiber were investigated. The results show that the PS/AlNPs melt is a typical shear thinning non-Newtonian fluid,and the apparent viscosity of the melt is negatively correlated with the temperature.The composite possesses non-Newtonian index of between 0.462 and 0.546 at 240-260 ℃,the coefficient of viscosity of about 1.8 to 2.1,and the activation energy of viscous flow sitting between 77.2 and 104.6 kJ mol-1,showing its good spinnability.The PS shows its ability to coat AlNPs very well and prohibits the AlNPs being oxided, giving birth to a PS/AlNPs fiber possessing smooth surface.The fiber has the biggest elongation at break and the highest break-ing strength when the content of AlNPs is 1 % and 5 %,respectively.关键词
