In this study, to improve the comprehensive properties of EP, a prospective four-in-one strategy was proposed to prepare composites by rationally introducing multifunctional nanofillers. First, phosphorus- and nitrogen-enriched nickel/iron bimetallic phyllosilicates (PN-NiFePS) were facilely synthesized and subsequently incorporated into EP to prepare high-performance composites. The results indicate that PN-NiFePS nanoparticles display unique rice-grain-shaped morphologies with rough surfaces, as numerous PN-NiFePS nanosheets were vertically grown on the crystalline surface of the metal-organic framework. The chemically grafted P/N-containing pendant chains enabled well-bonded polymer-filler interfaces and homogeneous dispersion, significantly enhancing the mechanical properties. With the increase filler concentration, the wear rate exhibits a trend of initial decrease followed by subsequent increase, reaching a minimum of 1.19×10<sup>−6</sup> mm<sup>3</sup>/(N·m) by adding 1% PN-NiFePS, which is 72% lower than pure EP. The incorporated PN-NiFePS endowed the composites with improved flame retardancy, leading to a steady increase in the limiting oxygen index and excellent self-extinguishing during combustion.

The dynamic behavior of a ring plays a critical role in determining its material properties. In this study, molecular dynamics simulations were performed to investigate the sliding dynamics of a ring on a rod-coil copolymer in rotaxane. We find that both the mean square displacement <i>g</i><sub>3</sub>(<i>t</i>) and the diffusion coefficient <i>D</i> of the rings are influenced by the rod-to-coil length ratio <i>α</i>, the stretching degree <i>μ</i> of the coil block, and the ring size <i>N</i><sub>ring</sub>.

Telechelic macromolecules were designed by tethering orthogonally arranged squaramide–amide hydrogen-bonding motifs to polydimethylsiloxane (PDMS) spacers.
