Today, one of the most widely used thermoplastic polymers in the world is polyethylene, which is used in various industries. Polyethylene has many applications due to its unique properties such as low cost of production and very good processability. But on the other hand, the weakness of this polymer in mechanical properties compared to metals has led to the use of additives such as various nanoparticles to improve it in most cases. Therefore, in recent years, the development of various nanocomposites based on polyethylene has become important. One of the common nanoparticles in the field of polymer nanocomposites is silica, which special features such as easy access, low toxicity, and high surface area and molecular stability have made this nanoparticle a suitable option for improvement the physical and mechanical properties of polymers. Also, in some cases, in order to solve the problem of the improper dispersion of these nanoparticles and agglomeration, the surface modification of these mineral materials by different methods has been the focus of researchers. In the recent studies, the use of pure and surface-modified silica nanoparticles in thermoplastic matrix, including polyethylene, has been reported to improvement the physical and mechanical properties of the polymer. In this paper, a review of the effect of the presence of pure silica nanoparticle and its surface-modified types on the crystallinity of nanocomposite based on various types of polyethylene is done.
