Covalent bonding
helps to improve interfacial interaction between filler and
matrix polymer thus deteChen et al. (2008) fabricated functionalized 1.5 wt%
multi-wall carbon nanotubes (MWCNT) nanocomposites and
reported the significant improvement of impact strength
from 5.5 kJ/m
2(neat epoxy) to 10.6 kJ/m
2rmine composite final mechanical
performance (Medhekar et al. 2010). Better wettability
and homogenous dispersion was observed from surface
modification.
