| 英文摘要 | The effects of maleated thermoplastic elastomer (tpeg) on morphological development of polypropylene (pp)/polyamide 6 (pa6) blends with a fixed pa6 content (30 wt %) were investigated. for purpose of comparison, nonmaleated thermoplastic elastomer (tpe) was also added to the above binary blends. a comparative study of ftir spectroscopy in above both ternary blends confirmed the formation of in situ graft copolymer in the pp/pa6/tpeg blend. dynamic mechanical analysis (dma) indicated that un-like tpe, the incorporation of tpeg remarkably affected both intensity and position of loss peaks of blend components. scanning electron microscopy (sem) demonstrated that pp/pa6/tpe blends still exhibited poor interfacial adhesion between the dispersed phase and matrix. however, the use of tpeg induced a finer dispersion and promoted interfacial adhesion. transmission electron microscopy (tem) for pp/pa6/tpeg blends showed that a core-shell structure consisting of pa6 particles encapsulated by an interlayer was formed in pp matrix. with the concentration of tpeg increasing, the dispersed core-shell particles morphology was found to transform from discrete acorn-type particles to agglomerate with increasing degree of encapsulation. the modified harkin's equation was applied to illustrate the evolution of morphology with tpeg concentration. "droplet-sandwiched experiments" further confirmed the encapsulation morphology in pp/pa6/tpeg blends. (c) 2006 wiley periodicals, inc. |
