In their work presented on page 2214, Irfan and colleagues report a series of pH‐sensitive hydrogels synthesized via frontal polymerization. The authors utilized several methods, including FTIR, DSC, SEM, dynamic mechanical analysis, and swelling measurements to characterize the synthesized hydrogels. The cover image shows several SEM images of the compact and uniform porous microstructures of the synthesized hydrogels. It was discovered that the hydrogel morphologies are largely dependent on itaconic acid/acrylic acid weight ratios. (DOI: 10.1002/pola.29502)

Irfan及其同事在第2214页的工作中报告了一系列通过额叶聚合合成的pH敏感水凝胶。作者利用多种方法，包括FTIR，DSC，SEM，动态力学分析和溶胀测量来表征合成的水凝胶。封面图像显示了合成水凝胶的致密且均匀的多孔微结构的数个SEM图像。发现水凝胶的形态在很大程度上取决于衣康酸/丙烯酸的重量比。（DOI：10.1002 / pola.29502）
