Surface charge on chitosan/cellulose nanowhiskers composite via functionalized and untreated carbon nanotube
Improvement in chitosan (CS) was achieved by solution casting using cellulose nanowhiskers (CNWs) and multiwall carbon nanotubes (MWCNTs) to synthesize CS/CNW functionalized/treated MWCNTs (CS/CNWs/f-MWCNTs) and CS/CNW untreated MWCNTs (CS/CNWs/Un-MWCNTs) nanocomposite films. A comparison between ef...

Improvement in chitosan (CS) was achieved by solution casting using cellulose nanowhiskers (CNWs) and multiwall carbon nanotubes (MWCNTs) to synthesize CS/CNW functionalized/treated MWCNTs (CS/CNWs/f-MWCNTs) and CS/CNW untreated MWCNTs (CS/CNWs/Un-MWCNTs) nanocomposite films. A comparison between effects of f-MWCNTs and Un-MWCNTs on CS/CNWs matrix have been studied with respect to change in their physical and mechanical properties. The surface morphology, chemical composition, mechanical properties and temperature decomposition of CS/CNWs/f-MWCNTs and CS/CNW/Un-MWCNTs nanocomposite films were characterized by Energy Dispersion Spectroscopy (EDS), Field Emission Scanning Electron Microscope (FESEM), Fourier-Transform Infrared Spectroscopy (FTIR) and Thermogravimetric Analysis (TGA). FESEM has shown that f-MWCNTs and Un-MWCNTs were well dispersed in CS/CNWs structure. Decrease in film ductility was observed with addition of Un-MWCNTs or f-MWCNTs. Moreover, Tensile strength (TS) and Young's modulus (YM) were increased with f-MWCNTs and seemed to be decreased in case of Un-MWCNTs.
