Influence of chemical functionalization of carbon nanotubes on their dispersibility in alkyl methacrylate polymer matrix
Nanocomposites based on poly(methyl methacrylate) (PMMA) and poly(methyl methacrylate-co-octadecyl methacrylate) (M/O) matrices and four different types of multiwall carbon nanotubes: pristine, oxidized (MWCNT-COOH), methyl ester (MWCNT-COOCH3) and dodecyl ester (MWCNT-COOC12H25) functionalized, were prepared in situ by radical (co)polymerization. The effectiveness of preparation of nanocomposites regarding dispersion and distribution of various MWCNT in polymer matrices was sized by SEM. In case of PMMA matrix the best dispersion and distribution were accomplished for MWCNT-COOCH3 due to their chemical resemblance with polymer matrix. After the introduction of 10 mol% of octadecyl methacrylate in polymer matrix a fairly good dispersion and distribution of MWCNT-COOCH3 were retained. The addition of 1 wt% of MWCNTs caused a significant reduction in the degree of polymerization of the PMMA matrix. But at the same time, the present MWCNTs increased storage modulus of PMMA nanocomposites except for dodecyl ester functionalized MWCNT.
