Designing synthetic nanoplatelets for the preparation of polypropylene nanocomposites
Polypropylene (PP) nanocomposites were prepared based on synthetic nanoplatelets via in situ polymerization. The designed α-ZrP derivatives contain methyl groups on the surface to increase hydrophobicity, which yield good compatibility with toluene and propylene molecules in the reactor. The incorporation of methyl groups on the layers of α-ZrP-derivatives also produces a "porous pathway" structure in the nanoplatelet gallery, which facilitates fast diffusion of propylene monomers. Both isotactic and syndiotactic PP nanocomposites were successfully prepared with a high level of exfoliation. The implication of the present findings is discussed.
