Carbon Nanotube Reinforced Natural Rubber Nanocomposite as a Stretchable Electronic Material
Source abstract
Abstract
A simple and low-cost solution casting method has been used to obtain carbon nanotube (CNT)-incorporated natural rubber (NR) composites. It is observed from the FESEM that CNTs are dispersed uniformly in the NR matrices, which is confirmed by the XRD and FTIR studies. TG–DTA study showed that the weight loss, calculated from the three-step degradation of NR, is minimum for the composite with 1.0 wt% of CNTs, which confirmed that thermal stability of the composites is increased, and degradation of the composites is delayed. With the increase in CNTs in the NR matrix, current density through the samples increases from 2.49 to 7.63 Am−2, which is due to the formation of continuous conductive networks and hopping conduction throughout the samples. The dielectric constant becomes almost double and the value of activation energy decreases from 0.259 to 0.226 eV with the increase in wt% of CNTs in the NR matrices. The tensile strength increases up to 0.46 (pm ) 0.02 MPa, which is more than three times higher compared to that of NR (0.13 (pm ) 0.03 MPa). Eventually, these NR nanocomposites may have major contribution in flexible and stretchable electronics such as in aerospace sectors, robotic arms, sensors, nonmetallic flexible capacitors and many more.
