Oxidation and silanization of MWCNTs for MWCNT/vinyl ester composites

Chemical functionalization of multi-wall carbon nanotubes (MWCNTs) is conducted by means of acid oxidation, direct silanization of the as-received MWCNTs and a sequential treatment based on oxidation and silanization. Polymer composites made from the functionalized MWCNTs and a vinyl ester resin are...
