Elastomeric Composites

ABSTRACTElastomeric composites based on Ethylene-Propylene-Diene-Monomer (EPDM) filled with multi-wall carbon nanotubes (MWNTs) have been prepared, showing improved mechanical properties as compared to the pure EPDM matrix. The results have been discussed using the Guth model. The main focus of the study was on the electrical behavior of the nanocomposites, in view of possible sensor applications. A linear relation has been found between conductivity and deformations up to 10% strain, which means that such materials could be used for applications such as strain or pressure sensors. Cyclic experiments were conducted to establish whether the linear relation was reversible, which is an important requirement for sensor materials.

Walled Carbon Nanotubes

Multi-walled carbon nanotubes (MWNTs) were used as filler to enhance thermal conductivity of Ethylene propylene diene monomer (EPDM) polymers. In order to study the thermal conductivity of the MWNTs/EPDM composites in three different directions, an experiment was conducted by the heat probe method. The results show the general average thermal conductivity of MWNTs/EPDM composites is 0.323 W/m•K，which is significantly higher than EPDM polymers. The maximum difference of thermal conductivity between two directions is 8.7% relative to the general average, indicating obvious anisotropic behavior.

Initial Modulus

Multi-walled carbon nanotubes (MWNTs) were used to prepare epoxidised natural rubber (ENR) nanocomposites. Our attempt to achieve nanostructures in MWNTs/ENR nanocomposites were formed by incorporating carbon nanotubes in a polymeric solution. Using this technique, nanotubes can be dispersed homogeneously in the ENR matrix with an attempt to increase the mechanical properties of these nanocomposites. The properties of the nanocomposites such as volume resistivity, tensile strength and tensile modulus were studied. Mechanical test results show an increase in the initial modulus for up to 14 times in relation to pure ENR. In addition to mechanical testing, the dispersion state of the MWNTs into ENR was studied by field emission electron microscopy (FESEM) and atomic force microscope (AFM) in order to understand the morphology of the resulting system. According to the present study, application of the physical and mechanical properties of carbon nanotubes to ENR can result in rubber products which have improved mechanical, physical and chemical properties.
