title = "Magnetic polypropylene nanocomposites: Property manupulation by Maleic anhydride grafted polypropylene with different molecular weights",
abstract = "Magnetic polypropylene (PP) polymer nanocomposites (PNCs) were fabricated with the reinforcing core-shell Fe-Fe203 nanoparticles (NPs) synthesized by an in-situ thermal decomposition method. Maleic anhydride functionalized PP (M-PP) with two different molecular weights (Mn=800, called LM-PP; Mn=8000, called HM-PP) were found not only serving as surfactant to control the particle size, but also influencing the oxidation degree of the synthesized NPs. With regular PP only, the average nanoparticle size was 15.9 ± 2.2 nm. The NPs size decreased to 10.6 ± 1.3 nm and 14.6 =t 2.7 nm in the presence of LM-PP and HM-PP, respectively. With only 2.4 wt% of M-PP in the PNCs, the complex viscosity was decreased by 86% at the frequency of 0.1 Hz. Enhanced saturated magnetization of the PNCs after introducing LM-PP indicated that the NPs were partially protected by the LM-PP shell and less dominated by the surface oxidation effects. The room temperature Mossbauer spectra analysis confirmed the oxidation degree of the NPs in each PNC and the molecular weight effect of M-PP on the restricted oxidation behavior of the NPs was studied as well.",
