Special Issue Information

Dear Colleagues,

Polymer composites and nanocomposites underpin applications from aerospace structures and energy storage to flexible electronics and biomedicine, owing to their high specific stiffness/strength, tunable damping and barrier properties, and opportunities for multifunctionality. Despite this progress, key challenges remain: the deliberate design of hierarchical architectures, spatial heterogeneity and anisotropy; the establishment of predictive, quantitative process–composition–structure–property–performance linkages; and the incorporation of realistic manufacturing routes (e.g., additive manufacturing, curing, melt processing, interfacial modification) into process-aware design frameworks. Computational modeling is uniquely positioned to address these issues. Recent advances span quantum and reactive molecular simulations that capture interfacial bond breaking/formation; coarse-grained MD and dissipative particle dynamics for mesoscale morphology evolution; phase-field and micromechanical models for damage and fracture; and finite-element or FFT-based homogenization frameworks that connect microstructure to macroscopic response. Nevertheless, substantive gaps persist, such as the following: efficient simulation at experimentally relevant time and length scales; rigorous chemo-thermo-mechanical coupling (e.g., curing kinetics, vitrimer bond exchange, interphase formation and aging); robust, physics-preserving multiscale upscaling; and verification/validation with in situ characterization. In this Special Issue, we invite contributions that address these challenges and advance the state of the art in computational modeling of polymer composites and nanocomposites.

In this work, models of the deformation behavior of polymer films of polyethylene and polyvinyl chloride are developed and analyzed, taking into account the influence of thickness, mechanical stress, temperature, time and dose of electron and ion irradiation. Experimental studies included tensile tests of polyethylene films of different thicknesses irradiated with krypton ions and electrons, as well as measuring the return deformation and its rate. It is shown that the quadratic and exponential models best describe the dependences of deformation on stress. Analytical formulas for the rate and acceleration of deformation are obtained, taking into account the influence of temperature and radiation dose. The results demonstrate a significant increase in the elastic properties and return deformation of irradiated samples, which is explained by the cross-linking of macromolecules and changes in the molecular structure under the influence of radiation. The proposed models and formulas can be effectively used in the development of devices and systems for monitoring the deformation of polymeric materials under radiation exposure in the aerospace, nuclear and electronic industries. Using the statistical analysis method, it was shown that the exponential model describes the dynamics of polyethylene deformation with a determination coefficient R2 = 0.985, which significantly exceeds the accuracy of the linear model (R2 = 0.85).
