Abstract

The first report of star poly(L-proline) crosslinkers is disclosed for digital light processing 3D printing of thermoresponsive hydrogels. Through chain end functionalization of star poly(L-proline)s with methacryloyl groups, access to high-resolution defined 3D hydrogel structures via digital light processing is achieved through photoinitiated free radical polymerization. Changing the poly(L-proline) molecular weight has a direct influence on both thermoresponsiveness and printability, while shape-morphing behavior can be induced thermally.

基于聚脯氨酸的星形多肽热致性水凝胶的数字光处理技术

首次报道了用于热致伸缩性水凝胶数字光处理三维打印的星形聚（L-脯氨酸）交联剂。通过甲基丙烯酰基对星形聚(L-脯氨酸)进行链端官能化，光引发自由基聚合可通过数字光处理获得高分辨率定义的三维水凝胶结构。改变聚(L-脯氨酸)的分子量对热响应性和可印刷性都有直接影响，同时还可以通过热诱导形变行为。
