A study on electrical properties of polymer enhancement by multiwalled carbon nanotube
Keywords:Composite materials, Epoxy resins, Multi walled carbon nanotubes
In this research study composite materials (Epoxy resins / multi walled carbon nanotubes) were prepared by mixing ratio of multi walled carbon nanotubes (MWCNTs) (1,2,3 and 4 %wt.). The techniques were implemented by mixing blend epoxy resins with MWCNTs through magnetic stirrer for 15min. Homogenize the blend was carried out using the homogenizer equipment ultrasonic liquid processor with high-intensity for 5min and followed by the addition of the hardener to the mixture. The molds prepared by casting EP/MWCNTs composite.
The electrical conductivity of EP/MWCNTs composite was obtained by A.C equipment. The results showed that there was an evolution from insulator state to semiconductor state when increasing the mixing ratios of MWCNTs. The electrical conductivity was improved by three orders than samples of pure epoxy resins matrix.
