Influence of Processing on the Properties of Carbon Nanotubes/Alumina Hybrid Compound Filled PDMS Composites

Abstract:

The aim of this study is to investigate the properties of Polydimethylsiloxane (PDMS)/MWCNT-Al₂O₃ nanocomposites. The multiwall carbon nanotubes MWCNT-Al₂O₃ hybrid compound was synthesized using chemical vapour deposition (CVD) method. The nanocomposites were produced by using Sonicator (ultrasonic processor) instrument and followed by casting in the vacuum oven. The content of MWCNT-Al₂O₃ was varied between 0.5 and 1.5% by weight. The results showed that the MWCNT-Al₂O₃ was well dispersed in PDMS. The interaction between PDMS and MWCNT-Al₂O₃ was investigated using Fourier transform infrared spectrometry (FTIR). The mechanical properties of the composite were examined by tensile test. The results showed that the greater of MWCNT-Al₂O₃ hybrid compound in PDMS composites resulted in lower tensile properties.
