Sažetak
Because of their unique structure and physical properties carbon nanotubes draw a lot of attention. Properties like large interfacial contact area, high stiffness and strength, great thermal and electrical conductivity, high aspect ratio and low mass density make them ideal reinforcement fillers. However, due to the Van der Waals interactions it is very challenging to prevent the agglomeration of carbon nanotubes in bundles. That's why an appropriate chemical treatment of the nanotube surface is required for a fine dispersion to be accomplished. Another reason for their surface functionalization is achieving better or specific interaction between carbon nanotubes and polymer matrix. In this work covalent modification of multiwall carbon nanotubes (MWCNT) was performed which has enabled introduction of new alkyl ending on carbon nanotube surface by ester or amide linkage. Modified MWCNT were characterized by spectroscopic and thermal methods.
