碩士 === 逢甲大學 === 纖維與複合材料學系 === 104 === This study focused on the morphology change of immiscible polymer, high-density polyethylene(HDPE) and polyamide 6(PA blends with the incorporation of GNSs to produce double double percolation, to find the direct relationship between the GNS content with compatibilizer introduce of blends and the network structure of GNSs. The conductivities of HDPE/PA6 composites filled with different amounts of GNS were measured by 4-point Probe and Source meter. The morphologies, GNS dispersion and crystallization behavior of HDPE/PA6/GNS composites were investigated by scanning electron microscopy (SEM), transmission electron microscopy (TEM), and differential scanning calorimetry (DSC). Analysis the ratio 50/50 HDPE/PA6 will produce co-continuous morphology by SEM and TEM, different content GNSs bring about morphology change. The GNSs located in HDPE/PA6 phases form conductive network, we find the double percolation bring in 3wt% and 5wt% of HDPE/PA6-6N/GNS and HDPE/PA6-10k/GNS, Incorporate the HDPE-g-MA will more improve the conductivity of HDPE/HDPE-g-MA/PA6-6N/GNS-M in 5wt%.
