✦ Synopsis

Nanocomposites based on semi-crystalline poly(vinyl alcohol) (PVA) and well-dispersed chemically functionalized singlewalled carbon nanotubes are combined through simple mixing. The interaction between the nanotubes and the polymer matrix is studied using optical and thermal methods. Significant enhancement of the mechanical properties is obtained for the functionalized-nanotube-based composites. These results imply that promoting nanotube dispersion and strong interfacial bonding through adequate functionalization of nanotubes improves the load transfer from the matrix to the reinforcing phase.
