Halloysite, a Dual Charge Nanotube, Effect on Polypropylene Nanocomposites Preparation via In situ Polymerization using Ziegler-Natta Catalyst

Organically modified halloysite nanotubes (OMHNTs) / polypropylene nanocomposites were prepared via in situ Ziegler-Natta catalyzed polymerization method. The polymerization was performed in the presence of ۶ and ۱۰ wt% of OMHNT. The results of XRD tests manifests that the hydroxyl groups present at the exterior surface of HNT were masked, without any changes in the lumen and interlayer spaces. Moreover, SEM images show the OMHNT proper distribution in the bulk of the synthesized nanocomposites.
