Effect of Carbon Nanotube Functionalization on the Structure and Properties of Poly(3-hydroxybutyrate)/MWCNTs Biocomposites
E-mail:
Multi walled carbon nanotubes (MWCNTs) covalently functionalized with an alkyl chain exhibited a better dispersion in poly(3-hydroxybutyrate) (PHB) solutions and cast films as compared with acid-treated MWCNTs (MWCNT-COOH) due to the much improved solubility in chloroform. The alkylated MWCNTs more effectively strengthened PHB composites than non-alkylated MWCNTs due to their uniform dispersion as well as stronger interaction of alkylated MWCNTs with the PHB matrix. Both acid-treated and alkylated MWCNTs added to PHB matrix facilitated crystallization kinetics. However the crystallization kinetics were found to be slower for the alkylated MWCNTs/PHB composites than acid-treated MWCNTs composites. The results may be ascribed to the inhibitory effect on PHB crystallization caused by the steric hindrance of the long alkyl chains attached to MWCNTs.
