Abstract

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.

用于光诱导 3D 打印的 Pluronics 快速微波辅助甲基丙烯酸化技术

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。
