Abstract

An alkyne-functionalized elastomer derived from sebacic acid, 1,3-propanediol, and alkyne-functionalized serinol is synthesized via melt condensation. A low-power UV lamp triggers the cross-linking rapidly via thiol-yne click chemistry. The cross-linking behavior is studied by photorheology and NMR spectroscopy. The resultant elastomer possesses mechanical properties similar to those of human soft tissues and exhibits degradability and good cytocompatibility.

摘要

一种由癸二酸、1,3 - 丙二醇和炔基官能化的丝氨醇衍生而来的炔基官能化弹性体通过熔融缩聚法合成。低功率紫外灯通过硫醇 - 炔点击化学迅速引发交联反应。通过光流变学和核磁共振光谱对交联行为进行了研究。所得弹性体具有与人软组织相似的机械性能，并表现出可降解性和良好的细胞相容性。
