Compressive Strain of Multi-Walled Carbon Nanotubes Embedded in Titania Matrix Doped With Silver Nanoparticles
Author(s):
Abstract:
Citrate colloidal silver nanoparticles were synthesized with 17 nm by Lee and Meisel technique. TiO2-Ag/MWCNTs nanocomposites were synthesized by sol-gel method. The size of colloidal silver nanoparticles were estimated under 20 nm by Dynamic Light Scattering DLS and Zeta analyzer. By Raman spectroscopic methodology different loading of MWCNTs into TiO2-Ag matrix were scanned in which it is an effective factor in shifting Raman frequencies bands. G band 1583 cm-1 that is one of the main bands of MWCNTs in above matrix, was analyzed and evaluated according to the shift of this band as a function of different loading percentages of MWCNTs. According to the amount of shifting of this band, the compressive strain of MWCNTs in the matrix was calculated that is more remarkable than the amount of the reported values in similar works.
