摘要

对 Pluronics 进行甲基丙烯酸化处理可实现不可逆水凝胶结构的三维打印，从而使其潜在应用领域更加多样化。目前的方法依赖于有机溶剂和耗时的反应。1H-NMR 分析表明，这种方法可以通过使用不同的甲基丙烯酸酐（MA）：Pluronic 比例，将 Pluronics 的甲基丙烯酸化度（MD）从 45% 调制到 97%。MD 较低的 3D 打印结构显示出较大的孔隙和较低的压缩模量。

Fast microwave-assisted methacrylation of Pluronics for photoinduced 3D printing

Methacrylation of Pluronics enables 3D printing of irreversible hydrogel constructs, thereby diversifying their potential applications. Current methods rely on organic solvents and time-consuming reactions. Herein, a rapid method for the microwave-assisted methacrylation of Pluronics by methacrylic anhydride (MA) in the absence of organic solvents is presented, which reduced the reaction time from 24 h to ca. 10 min. ¹H-NMR analysis showed that this method allows modulating the methacrylation degree (MD) of Pluronics from 45 to 97% by using different MA:Pluronic ratios. 3D-printed constructs with lower MD showed larger pores and lower compression modulus.
