The effect of incorporating carbon nanotubes on impact, transverse strength, hardness, and roughness to high impact denture base material
Main Article Content
Abstract
Materials and methods: Three concentrations of carbon nanotubes was used 0.5%, 1%, 1.5% in a pilot study to see the best values regarding transverse strength, impact, hardness and roughness test, 1 wt% was the best concentration, so new samples for control group and 1wt% carbon nanotubes and the previous tests were of course repeated.
Results: There was a significant increase in impact strength and transverse strength when we add carbon nanotubes in 1wt%, compared to control group where as hardness decrease when adding carbon nanotubes.
Conclusion: the addition of carbon nanotubes improves the physical and mechanical properties.
Key words: Carbon nanotubes, high impact denture base.
