| 中文摘要 | the properties of miscible phenolphthalein poly(ether ether ketone)/phenoxy (pek-c/phenoxy) blends have been measured by dynamic mechanical analysis and tensile testing. the blends were found to have single glass transition temperatures (t(g)) that vary continuously with composition. the tensile moduli exhibit positive deviations from simple additivity. marked positive deviations were also observed for tensile strength. the tensile strengths of the 90/10 and 75/25 pek-c/phenoxy blends are higher than those of both the pure components. embrittlement, or transition from the brittle to the ductile mode of failure, occurs in the composition range of 50-25 wt% pek-c. these observations suggest that mixing on the segmental level has occurred and that there is enough interaction between the components to decrease its internal mobility significantly. pek-c was also found to be miscible with the epoxy monomer, diglycidyl ether of bisphenol a (dgeba), as shown by the existence of a single glass transition temperature (t(g)) within the whole composition range. miscibility between pek-c and dgeba could be considered to be due mainly to entropy. however, pek-c was judged to be immiscible with the diaminodiphenylmethane-curved epoxy resin (ddm-cured er). it was observed that the pek-c/er blends have two t(g), which remain invariant with composition and are almost the same as those of the pure components, respectively. scanning electron microscopy showed that the pek-c/er blends have a two-phase structure. the different miscibility with pek-c between dgeba and the ddm-cured er is considered to be due to the dramatic change in the chemical and physical nature of er after curing. |
