  通过耐氧的光酶RAFT聚合，以多种结构实现非共轭单体的超高分子量。

  摘要：

  获得可定义的超高分子量（UHMW）聚合物是可逆失活自由基聚合领域的不懈追求。已经成功地开发了合成方案以仅从共轭单体获得具有低分散性的UHMW，而未共轭单体的聚合没有提供相同水平的控制。本文利用耐氧光酶R​​AFT（可逆加成-断裂链转移）聚合技术解决了10°C下非共轭单体的这一难题，从而能够以接近定量的转化率轻松合成定义明确，线性和星形的聚合物，这是前所未有的超高分子量和低分散性。对组成，MW和架构的控制非常精细，并且操作简便，条件温和，环境友好，

  application of reversible degenerative radical polymerization (RDRP) in the construction of polymer networks (PNs) provides a facile and convenient way to fabricate 3D objects with the ability to be posttransformed. However, the polymerization mechanism mainly relies on chain-growth polymerization, which limits its wide application for various polymeric materials with different functionalities. Here

  可逆退化自由基聚合 (RDRP) 在聚合物网络 (PN) 构建中的应用为制造具有后转换能力的 3D 物体提供了一种简便的方法。但其聚合机理主要依赖于链增长聚合，限制了其在各种不同功能高分子材料中的广泛应用。在这里，我们提出了一种利用光诱导 RAFT 逐步生长聚合来实现 PN 的方法，该聚合基于黄原酸酯和烷基乙烯基之间的 RAFT 单单元单体插入 (SUMI) 反应。受益于该反应，在聚合过程中主链的每个重复单元中都可以生成悬垂的 RAFT 试剂。这些可再激活的休眠物种可进一步用于通过多官能单体的逐步生长聚合制备的 PN 的后官能化。此外，由于酯基的引入，制备的 PNs 是可降解的，为可降解和刺激响应材料提供了途径。

  Photoinduced 3D printing based on the reversible addition‐fragmentation chain transfer (RAFT) process has emerged as a robust method for creating diverse functional materials. However, achieving precise control over the mechanical properties of these printed objects remains a critical challenge for practical application. Here, we demonstrated a RAFT step‐growth polymerization of a bifunctional xanthate and bifunctional vinyl acetate. Additionally, we demonstrated photoinduced 3D printing through RAFT step‐growth polymerization with a tetrafunctional xanthate and a bifunctional vinyl acetate. By adjusting the molar ratio of the components in the printing resins, we finely tuned the polymerization mechanism from step‐growth to chain‐growth. This adjustment resulted in a remarkable range of tunable Young's moduli, ranging from 7.6 MPa to 997.1 MPa. Moreover, post‐functionalization and polymer welding of the printed objects with varying mechanical properties opens up a promising way to produce tailor‐made materials with specific and tunable properties.

  摘要基于可逆加成-碎片链转移（RAFT）工艺的光诱导三维打印技术已成为制造各种功能材料的可靠方法。然而，实现对这些打印对象机械性能的精确控制仍然是实际应用中的一个关键挑战。在这里，我们展示了双官能黄原酸酯和双官能醋酸乙烯酯的 RAFT 梯级生长聚合。此外，我们还利用四官能黄原酸酯和双官能乙酸乙烯酯通过 RAFT 梯级生长聚合反应演示了光诱导 3D 打印。通过调整打印树脂中各组分的摩尔比，我们对聚合机制进行了微调，从阶跃生长转变为链式生长。调整后，杨氏模量的可调范围非常大，从 7.6 兆帕到 997.1 兆帕不等。此外，对具有不同机械性能的打印物体进行后功能化和聚合物焊接，为生产具有特定可调性能的定制材料开辟了一条前景广阔的途径。
