Influence of Ultrasonic Treatment on Electromagnetic Characteristicsof Composites Based on Multiwall Carbon Nanotubes at Wide Range of Frequencies (100 Hz – 258 GHz)

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.

Multiwall Carbon

There is a growing demand for light and radar absorbing materials in both commercial and military purposes. In this paper, microwave properties of polimer based composites containing multiwalled carbon nanotubes used as fillers have been analyzed. The multiwall carbon nanotubes used in the composite were about 9.4 nm in diameter. The results show that the ultrasonic treatment modifies the dielectric properties of the composite. Both real and imaginary permittivity of composites is 2 times more than ordinary example after sonicating for 3 minutes.

Nanotube Films

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.
