Rubber finds wide range of application in automotive sector starting from tires to rubber bushes. Incorporation of nanoparticles like carbon nanotubes to rubber has improved the mechanical properties significantly. Still dispersion of carbon nanotube in raw rubber is a challenging process. In this work multiwall carbon nanotubes (MWCNT) are dispersed in the varying proportions (0.5, 1, 1.5 wt.%) in high viscous aromatic rubber processing oil using high shear planetary ball mill for a period of 2 hours. Then the rubber nanocomposites have been processed in double roll mill by adding the chemicals in the following order (Natural Rubber, Antioxidant: 1 phr, Oil: 5 phr, Zinc Oxide: 4 phr, Stearic Acid: 2 phr, Accelerator: 1 phr, Sulfur: 2 phr). It was found that, the incorporation of Multiwall carbon nanotube (MWCNT) has improved the mechanical properties of natural rubber significantly. Din abrasion studies show improvement in wear resistance of natural rubber incorporated with multiwall carbon nanotube.

The aim of this paper is to study the high load of multiwall carbon nanotubes (MWCNTs) in natural rubber (NR) matrix. Firstly, the rubber matrix, fillers, and crosslinker are thoroughly mixed together in two-roll mill. Rheological tests are done from which scorch time, cure time, and cure index are estimated. The kneaded mixer is then compression molded, dumb bell samples as per ASTM D412 are prepared, and tensile strength, tensile modulus, elongation at break, and hardness are measured. It is noticed that NR/30% MWCNT has shown the highest tensile strength of 23.38 MPa and Shore A hardness of 90, which is 78.18% and 91.5%, respectively, higher than the unfilled NR. The increase in strength and hardness, the ductility loss, and decrease in elongation at break are observed upon increase in filler. FTIR, SEM, and AFM examinations are done and the results show high dispersion of nanofillers and strong interfacial interaction with rubber, which is responsible for overall enhancement in mechanical properties of the nanocomposites. Furthermore, the nonlinear material constants are evaluated through extended tube model and corresponding nonlinear material constants of different filler compositions are presented for the designers to use them in their component design and analysis.

By exploiting the dispersibility and rigidity of boehmite nanofibers (BNFs) with a high aspect ratio of 4 nm in diameter and several micrometers in length, multiwall-carbon nanotubes (MWCNTs) were successfully dispersed in aqueous solutions. In these sols, the MWCNTs were dispersed at a ratio of about 5–8% relative to BNFs. Self-standing BNF–nanotube films were also obtained by filtering these dispersions and showing their functionality. These films can be expected to be applied to sensing materials.
