Multi‐Wall Carbon Nanotubes/Styrene Butadiene Rubber (SBR) Nanocomposite

Abstract

A floating catalyst chemical vapor deposition (FC-CVD) method was designed and fabricated to produce high-quality and-quantity carbon nanotubes. The design parameters like the hydrogen flow rate; reaction time and reaction temperature were optimized to produce high yield and purity of Multi-Wall Carbon Nanotubes (MWCNTs). Multi-Walled Carbon Nanotubes (MWNTs) were used to prepare natural rubber (NR) nanocomposites. Our first efforts to achieve nanostructures in MWNTs/styrene butadiene rubber (SBR) nanocomposites were formed by incorporating carbon nanotubes in a polymer solution and subsequently evaporating the solvent. Using this technique, nanotubes can be dispersed homogeneously in the NR matrix in an attempt to increase the mechanical properties of these nanocomposites. The properties of the nanocomposites such as tensile strength, tensile modulus, elongation at break and hardness were studied. Using different percentages of carbon nanotubes from 1 wt% to 10 wt%, several nanocomposites samples were fabricated. Significant improvements in the mechanical properties of the resulting nanocomposites showed almost 10% increase in the Young's modulus for 1 wt% of CNTs and up to around 200% increase for 10 wt% of CNTs.

Fluidized bed catalytic chemical vapor deposition synthesis of carbon nanotubes—A review

“…It is prudent to note that CNTs are currently produced with a relatively high quality, as it is depicted in Fig. 2 [11], but in limited quantities. In this review, the findings of more than 100 published papers for the development of engineering solutions for CNT manufacturing are presented and discussed.…”

Mechanical performance of styrene-butadiene-rubber filled with carbon nanoparticles prepared by mechanical mixing

“…less than 10 phr, using solution mixing method leads to significant improvement in the mechanical properties, e.g. as high as 10-fold and 2-fold in modulus and strength, respectively [24][25][26][27][28], as well as low filler networking concentration (percolation threshold), e.g. as low as 2 phr [24,29,30].…”

Physicomechanical properties of wollastonite (CaSiO3)/styrene butadiene rubber (SBR) nanocomposites

“…Researchers have already been used different fillers in different polymer matrices such as calcium carbonate, fly ash, carbon nanotubes (CNTs), multi‐walled CNTs, carbon black, nanoclays, organomodified nanoclays, wollastonite, alumina clay, ZnO, Fe 3 O 4 , magnesium hydroxide, calcium sulphate, and Ca 3 (PO 4 ) 2 to study the thermal, rheological, mechanical, morphological, and flame retardant properties of polymer composites and their filler interactions. Basically, the main purpose of addition of mineral fillers in polymers is to reduce the cost and to give extra functionality.…”
