Preparation and Characterization of MWCNTs-Chitosan Composite

Abstract

The present work aims to prepare Multi-walled carbon nanotube acid (M WCNTs-COOH) by using fragments Flam Deposition technique (FFD), grafting CNTS with Chitosan (CS) to prepare (CS-OMWCNTs)composite. Each of the following techniques is used to characterize the components of composite x-ray diffraction (X-RD), Fourier Transform Infra Red (FT-IR), Raman spectra, Field emission scanning electron microscopy (FESEM), transmitted electron microscope (TEM), and Laser Particle Size Analyzer technology. The results of the laser particle size analyzer showed that the particle size ranged between (87.8-403.3). Pattern of XRD showed that its diffraction spectrum contains crystalline materials with a good atomic arrangement of atoms with graphite, while SEM microscopy revealed that the average diameter of the tube was 40 nm. Raman Spectroscopy showed ID/IG ratio of 0.6, which means a lower degree of distortion in the compositional structure of the carbon nanotube. AS for TEM technology, it showed the attachment of carbon nanotube to the surfaces of chitosan. FT-IR showed the active groups present on the surface of carbon nanotube such as (COOH, OH)
