The reinforce effect of carbon nanotube on the polymer composite basing on the natural rubber/ styrene butadiene rubber and natural rubber/polypropylene).

Abstract

In this work, the influences of multi-walled carbon nanotubes (MWCNTs) on mechanical properties and structure of polymer blends natural rubber/polypropylene (NRlPP=50/50) and natural rubber/styrene butadiene rubber (NRlSBR = 50/50) were characterized. There was a maximal reinforcement effect at ratio of 1% wt. MWCNTs for both polymer blends determined. The thermo mechanical analysis (TMA) and the stress cycle measurements of samples after accelerated climate test showed that polymer composite basing on NR/SBR/MWCNT was more stable than NR/SBR/MWCNT. Transmission electron microscope examinations proved that MWCNTs well distributed and well adhered to polymer blends.
