Polypropylene Nanocomposites Based on Designed Synthetic Nanoplatelets
Synthetic nanoplatelets derived from R-zirconium phosphate (R-ZrP) were prepared for in situ propylene
polymerization, yielding polypropylene (PP) nanocomposites. The designed R-ZrP-derivatives contain
methyl groups on the surface to increase hydrophobicity, which gives rise to a better compatibility with
toluene and propylene molecules. The incorporation of methyl groups on the layers of R-ZrP-derivatives
also produces a “porous pathway” structure in the nanoplatelet gallery, which facilitates the diffusion of
propylene monomers. PP/R-ZrP nanocomposites were successfully prepared with a high level of exfoliation.
The implications of the present findings are discussed.
