is a daunting task to prepare polyolefin nanocomposites that
contain well-exfoliated nanoplatelets due to the nonpolar and high
crystallinity nature of polyolefins. In this research, a robust approach
was developed to prepare polyethylene (PE) nanocomposites by grafting
maleated polyethylene (MPE) onto pre-exfoliated α-zirconium
phosphate (ZrP) nanoplatelets via a simple amine-anhydride reaction
to form ZrP-g-MPE. Several variables, including maleic
anhydride (MA) content, MPE graft density, MPE molecular weight, and
PE matrix crystallinity, were investigated to determine how they influence
ZrP-g-MPE dispersion in PE. It was found that grafted
PE has a different morphology and that the long PE brushes with medium
graft density on ZrP can achieve sufficient chain entanglement and
cocrystallization with PE matrix to stabilize and maintain ZrP-g-MPE dispersion after solution or melt mixing. This leads
to enhanced Young’s modulus, yield stress, and ductility. The
structure–property relationship of PE/ZrP-g-MPE nanocomposites and usefulness of this study for the preparation
of high-performance polyolefin nanocomposites are discussed.
