The force field achieves energy and force root-mean-square errors of 1.3 meV/atom and 159 meV/Å, respectively, and operates approximately 1200 times faster than ab initio molecular dynamics. MD simulations demonstrate excellent predictive capabilities across multiple critical thermos-mechanical properties (radial distribution function, density, and elastic modulus), with results being well consistent with experimental values. In particular, the force field can provide accurate prediction of the bond dissociation energies for typical bonds with a mean absolute error of 7.8 kcal/mol (<8%), which enables the simulation of tensile-induced failure caused by chemical bond breaking.

We successfully prepared self-reinforced HDPE pipes with a three-layer structure combining spherical and shish-kebab crystals. Rotational processing aligned the molecular chains in the ring direction and formed shish-kebab crystals. As a result, the annular tensile strength of the rotationally processed three-layer shish-kebab structure (TSK) pipe increased from 26.7 MPa to 76.3 MPa, an enhancement of 185.8%. Notably, while maintaining excellent tensile strength (73.4 MPa), the elongation at break of the spherulite shishkebab spherulite (SKS) tubes was improved to 50.1%, as compared to 33.8% in the case of shish-kebab spherulite shish-kebab (KSK) tubes. This improvement can be attributed to the changes in the micro-morphology and polymer structure within the SKS tubes, specifically due to the formation of small-sized shish-kebab crystals and the low degrees of interlocking.In addition,2D-SAXS analysis revealed that KSK tubes have higher tensile strength due to smaller crystal sizes and larger shish dimensions, forming dense interlocking structures. In contrast, the SKS and TSK tubes had thicker amorphous regions and smaller shish sizes, resulting in reduced interlocking and mechanical performance.</p></div>","PeriodicalId":517,"journal":{"name":"Chinese Journal of Polymer Science","volume":"43 9","pages":"1616 - 1628"},"PeriodicalIF":4.0,"publicationDate":"2025-07-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144918501","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This inverse design problem involves searching within a vast combinatorial phase space defined by components, sequences, and topologies, and is often computationally intractable due to its NP-hard nature. At the core of this challenge lies the need to evaluate complex correlations among structural variables, a classical problem in both statistical physics and combinatorial optimization. To address this, we adopt a mean-field approach that decouples direct variable-variable interactions into effective interactions between each variable and an auxiliary field. The simulated bifurcation (SB) algorithm is employed as a mean-field-based optimization framework. It constructs a Hamiltonian dynamical system by introducing generalized momentum fields, enabling efficient decoupling and dynamic evolution of strongly coupled structural variables. Using the sequence optimization of a linear copolymer adsorbing on a solid surface as a case study, we demonstrate the applicability of the SB algorithm to high-dimensional, non-differentiable combinatorial optimization problems. Our results show that SB can efficiently discover polymer sequences with excellent adsorption performance within a reasonable computational time. Furthermore, it exhibits robust convergence and high parallel scalability across large design spaces. The approach developed in this work offers a new computational pathway for polymer structure optimization. It also lays a theoretical foundation for future extensions to topological design problems, such as optimizing the number and placement of side chains, as well as the co-optimization of sequence and topology.</p></div>","PeriodicalId":517,"journal":{"name":"Chinese Journal of Polymer Science","volume":"43 10","pages":"1739 - 1748"},"PeriodicalIF":4.0,"publicationDate":"2025-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145242630","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
