Special Issue Information

Dear Colleagues,

Due to their disordered out-of-equilibrium nature, polymeric solids exhibit a complex structure–property relationship that challenges the rational design of polymer materials and their products with tailored properties. By adding extra phases into the polymeric matrix, polymer composites feature an increasing extent of structural complexity, which, in turn, significantly enhances the tunability of their properties but renders their rational design even harder. With the recent advances in computational materials science, physics- and data-driven modeling—including simulations and machine learning—offer an attractive opportunity to revisit these challenges facing polymer composite design.
In this Special Issue, we invite contributions that address several aspects pertaining to the modelling and inverse design of polymer composites, including those that decipher the structure–property relationship of polymeric solids by conventional modeling tools (such as molecular dynamics simulations and finite element analysis), develop new simulation schemes to predict polymer properties by simplifying the underlying physics, build surrogate simulation engines of polymer composites by machine learning, and combine high-throughput simulations and machine learning to accelerate the discovery of novel polymer materials. More broadly, any original contributions (including reviews) relevant to rationalizing computational modeling of polymer composites and their inverse design are welcome. We hope that this Special Issue will modestly help to stimulate new developments in that direction.

Because of the complex nonlinear relationship between working conditions, the prediction of tribological properties has become a difficult problem in the field of tribology. In this study, we employed three distinct machine learning (ML) models, namely random forest regression (RFR), gradient boosting regression (GBR), and extreme gradient boosting (XGBoost), to predict the tribological properties of polytetrafluoroethylene (PTFE) composites under high-speed and high-temperature conditions. Firstly, PTFE composites were successfully prepared, and tribological properties under different temperature, speed, and load conditions were studied in order to explore wear mechanisms. Then, the investigation focused on establishing correlations between the friction and wear of PTFE composites by testing these parameters through the prediction of the friction coefficient and wear rate. Importantly, the correlation results illustrated that the friction coefficient and wear rate gradually decreased with the increase in speed, which was also proven by the correlation coefficient. In addition, the GBR model could effectively predict the tribological properties of the PTFE composites. Furthermore, an analysis of relative importance revealed that both load and speed exerted a greater influence on the prediction of the friction coefficient and wear rate. Full article
