**Abstract**
 The effect of poly(2-ethyl-2-oxazoline) (PEOX) as a surface modifier for multi-walled carbon nanotubes (MWCNTs) in a poly(vinyl alcohol) (PVA) composite was studied through a simple polymer wrapping and melt extrusion processes. MWCNTs were carboxylated in a reaction with HNO3, followed by mixing with 10 wt.% PEOX in ethanol to produce a MWCNT-PEOX complex. High resolution transmission electron microscopy identified a PEOX layer existing on the surface of MWCNTs. Compared with pristine MWCNTs, MWCNT-PEOX showed an improved dispersion in hydrophilic solvents such as water and ethanol. The PVA composite reinforced with 0.5 wt.% MWCNT-PEOX exhibited 54% higher Young's modulus than pure PVA. 20 Refs.
