Abstract

A nanocomposite can include a polyolefin composition having at least one polyolefin. The polyolefin composition can have a multimodal molecular weight distribution, such as a bimodal molecular weight distribution. The nanocomposite can also include at least 5% by weight of nanoparticles, relative to a total weight of the nanocomposite. The nanoparticles can be carbon nanoparticles, silicon nanoparticles, or SiC nanoparticles. A nanocomposite masterbatch can be prepared by melt blending the polyolefin composition with the nanoparticles. A polyolefin resin can be prepared by blending the nanocomposite with a polyolefin. Formed articles can include the polyolefin resin.
