AI Article Synopsis
- A simple solution-evaporation method was used to create chitosan/multiwalled carbon nanotubes (MWNTs) nanocomposites.
- Characterization techniques like SEM, TEM, and XRD were used to analyze the structure and mechanical strengths of these nanocomposites, revealing that MWNTs were evenly distributed in the chitosan matrix.
- The addition of just 0.8 wt % of MWNTs significantly enhanced the mechanical properties of the composites, improving tensile modulus and strength by approximately 93% and 99%, respectively, compared to plain chitosan.
Article Abstract
Biopolymer chitosan/multiwalled carbon nanotubes (MWNTs) nanocomposites have been successfully prepared by a simple solution-evaporation method. The morphology and mechanical properties of the chitosan/MWNTs nanocomposites have been characterized with field emission scanning electron microscopy (SEM), bright field transmission electron microscopy (TEM), optical microscopy (OM), wide-angle X-ray diffraction (XRD), and tensile as well as nanoindentation tests. The MWNTs were observed to be homogeneously dispersed throughout the chitosan matrix. When compared with neat chitosan, the mechanical properties, including the tensile modulus and strength, of the nanocomposites are greatly improved by about 93% and 99%, respectively, with incorporation of only 0.8 wt % of MWNTs into the chitosan matrix.
