چکیده مقاله:

In this study, physical and mechanical properties of polypropylene nanocomposites in the presenceof carbon nanotubes (MWCNT) are studied. Nanocomposites were prepared by combining differentpercentages of melt mixing method. Mechanical and physical properties such as the fracture surfacemorphology, distribution of CNTs in the material field, the size of the crystals, crystallization and meltingtemperature, tensile strength, flexural and impact strength and flexural modulus were analyzed. Insummary, it was shown that Young s modulus and flexural an increase in the weight of MWCNT, areconsiderably improved. However, the distribution of the nanotubes was poorer in material terms, themelting temperature has not noticeably changed. Also, the sizes of the crystals in some Miller s pages weredecreased. By increasing the amount of MWCNT, an increase in crystallization temperature of PP isobserved. Loading 1.5%wt of MWCNT, the amount Tp has increased about 14.3 oC than pure PP. Byincreasing of MWCNT to 0.4%wt mechanical properties were improves. Then changing MWCNT to0.8%wt, mechanical properties is reduced.
