Room temperature sorption kinetics is conducted on semi-crystalline ethylene-co-butyl acrylate (EBA) polymer samples filled with different contents of carbon black (CB) in polar (ethanol) or non-polar (toluene) solvents. Equilibrium swelling data obtained by solvent uptake measurements are found to decrease as the CB content increases. This is due to the increase of the crosslink density and tortuosity inside the EBA/CB samples. The preferential area occupied by the solvent molecules in the samples is determined by analyzing the behavior of the wetting coefficient. Higher equilibrium uptake and faster solvent penetration are observed for toluene compared to the case of ethanol. Billmeyer's approach, that is phenomenologically sound and insightful while mathematically straightforward to implement, is applied where the specific parameters of this approach are determined from experiments. Subsequently, the transport mechanisms are discussed using the Peppas-Sahlin and Berens-Hopfenberg relaxation-diffusion models. A significant drop in the tensile properties is observed in the swollen samples compared to their dry counterparts. Furthermore, the sorption data and the mechanical response are found to be well correlated. Additionally, the stress-strain curves of the swollen and dry samples under large deformation are analyzed with the Haward-Thackray model by considering microstructure characteristics (CB content, strain hardening modulus, entanglement, cross-linking degree and polymer-solvent interaction).

对在极性（乙醇）或非极性（甲苯）溶剂中填充不同含量炭黑 (CB) 的半结晶乙烯-丙烯酸丁酯 (EBA) 聚合物样品进行室温吸附动力学研究。发现通过溶剂吸收测量获得的平衡溶胀数据随着炭黑含量的增加而降低。这是由于 EBA/CB 样品内部交联密度和曲折度的增加。通过分析润湿系数的行为来确定样品中溶剂分子占据的优先区域。与乙醇相比，甲苯具有更高的平衡吸收和更快的溶剂渗透。Billmeyer 的方法在现象学上是合理且富有洞察力的，同时在数学上易于实施，在这种方法的具体参数由实验确定的情况下应用。随后，使用 Peppas-Sahlin 和 Berens-Hopfenberg 弛豫扩散模型讨论了传输机制。与干燥样品相比，在溶胀样品中观察到拉伸性能显着下降。此外，发现吸附数据和机械响应有很好的相关性。此外，通过考虑微观结构特征（CB 含量、应变硬化模量、缠结、交联度和聚合物-溶剂相互作用），使用 Haward-Thackray 模型分析大变形下溶胀和干燥样品的应力-应变曲线。使用 Peppas-Sahlin 和 Berens-Hopfenberg 弛豫扩散模型讨论了传输机制。与干燥样品相比，在溶胀样品中观察到拉伸性能显着下降。此外，发现吸附数据和机械响应有很好的相关性。此外，通过考虑微观结构特征（CB 含量、应变硬化模量、缠结、交联度和聚合物-溶剂相互作用），使用 Haward-Thackray 模型分析大变形下溶胀和干燥样品的应力-应变曲线。使用 Peppas-Sahlin 和 Berens-Hopfenberg 弛豫扩散模型讨论了传输机制。与干燥样品相比，在溶胀样品中观察到拉伸性能显着下降。此外，发现吸附数据和机械响应有很好的相关性。此外，通过考虑微观结构特征（CB 含量、应变硬化模量、缠结、交联度和聚合物-溶剂相互作用），使用 Haward-Thackray 模型分析大变形下溶胀和干燥样品的应力-应变曲线。
