“…In addition, it was also found that adding graphene oxide nanosheets to cyclic ultrahigh‐molecular‐weight PE helps to form crystals with high melting temperatures 87 . Previously, with the help of dynamic MC simulation, our group comparatively studied the crystallization behaviors of cyclic and linear polymer nanocomposites, and found that the filled cyclic polymers exhibit higher melting temperature, higher crystallization temperature, and faster crystallization rate, especially in the systems with relatively short chains 88 . In other words, the nanofiller exhibits the same promotion effects on the crystallization process of cyclic and linear polymers.…”

“…Block copolymers have been widely investigated because of their fascinating ability to self‐assemble into different sophisticated structures. As we all know, in block copolymers, the repulsive interaction between chemically different blocks will cause sequence separation, while the chemical bonds connecting the sequences hinder the macroscopic phase separation as in the blend 87–92 . In the delicate balance of these two effects, microphase separation will occur between different blocks.…”

“…As we all know, in block copolymers, the repulsive interaction between chemically different blocks will cause sequence separation, while the chemical bonds connecting the sequences hinder the macroscopic phase separation as in the blend. [87][88][89][90][91][92] In the delicate balance of these two effects, microphase separation will occur between different blocks. For the crystalline-amorphous diblock copolymers, the final crystal morphology is mainly governed by the crystallization process and microphase separation, resulting in more complex, and richer structures.…”

Polymer nanocomposites are widely used in industry due to their excellent mechanical properties. Polymer crystallization in polymer nanocomposites can effectively enhance the interfacial interactions between polymer matrix and nanofillers, thereby providing new ideas for preparing high-performance polymer materials. In recent years, molecular simulation has gradually become a powerful research tool for the investigation of polymer materials and physics. In this article, the latest simulation research progress on the crystallization behaviors of polymer nanocomposites under different conditions is reviewed, and the influences of various factors on the crystallization behaviors of homopolymers, copolymers, and oriented polymers filled with nanofillers, as well as polymers grafted on nanofillers are summarized and discussed.It is highly expected that the current review can supply some new insights into the development and design of new nanohybrid structures and then the control of the physical properties of polymer nanocomposites.

In this work, the effects of functionalized carbon nanofillers (i.e., CNT‐g‐PE prepared by carbon nanotubes grafted with linear polyethylene) on the crystallization of cyclic polyethylene were revealed by molecular dynamics simulation, and compared with that of pure cyclic polyethylene(C‐PE) and carbon nanotube / cyclic polyethylene blends(C‐PE/CNT). The simulation results show that the CNT‐g‐PE has an anti‐nucleation effect on the cyclic polyethylene, the crystallinity and crystallization rate of the C‐PE/CNT‐g‐PE system are significantly lower than those of the other systems. This phenomenon can be explained by the topological effect when linear polyethylene chains grafted on carbon nanotubes are mixed with cyclic polyethylene. It is observed from the micro‐scale that when the linear polyethylene chains are in contact with cyclic polyethylene, the cyclic chains are passed through by the linear chains to form a transient entanglement network, further affecting the dynamic process of the molecular chains. The diffusion and orientation of the cyclic polyethylene molecular chain are inhibited. This limits the crystal nucleation efficiency and growth kinetics. These simulation results not only support some experimental findings, but also confirm some microscopic phenomena that are difficult to observe in the experiment, which provides some inspirations for the experimental design of high‐performance nanocomposite materials.
