This comment critically evaluates the work of Dehaghani , who investigated the conformational behavior of catenated polymers under diverse solvent conditions using coarse-grained molecular dynamics simulations. While their study provides valuable insights into the scaling behavior of poly[]catenane's radius of gyration in a good solvent, significant discrepancies arise, particularly concerning the reported -temperature trends. The validity of their methodology in determining -temperatures for linear and ring polymers is questioned, given observed disparities in chosen number of bead ranges that imply varying molecular weights. This comment underscores the need for a meticulous reassessment of the methodologies and interpretations presented in Dehaghani 's study, emphasizing the importance of rigorous considerations in the investigation of the physical properties of catenated polymers.
本评论批判性地评估了德哈加尼的工作，他使用粗粒度分子动力学模拟研究了在不同溶剂条件下连环聚合物的构象行为。虽然他们的研究为聚[连环烷]在良溶剂中的回转半径的标度行为提供了有价值的见解，但仍存在重大差异，特别是在报道的温度趋势方面。鉴于观察到在所选珠子范围数量上的差异意味着分子量不同，他们用于确定线性和环状聚合物温度的方法的有效性受到质疑。本评论强调需要对德哈加尼研究中提出的方法和解释进行细致的重新评估，强调在研究连环聚合物物理性质时进行严格考量的重要性。
