This review article aims to cover the most recent advances regarding the synthesis of linear ABC-type triblock terpolymers and star-shaped polymers by RAFT polymerization, as well as their self-assembly properties in aqueous solutions. RAFT polymerization has received extensive attention, as it is a versatile technique, compatible with a great variety of functional monomers and reaction conditions, while providing exceptional and precise control over the final structure, with well-defined side-groups and post-polymerization engineering potential. Linear triblock terpolymers synthesis can lead to very interesting novel ideas, since there are countless combinations of stimuli/non-stimuli and hydrophilic/hydrophobic monomers that someone can use. One of their most interesting features is their ubiquitous ability to self-assemble in different nanostructures depending on their degree of polymerization (DP), block composition, solubilization protocol, internal and external stimuli. On the other hand, star-shaped polymers exhibit a more stable nanostructure, with a distinct crosslinked core and arm blocks that can also incorporate stimuli-responsive blocks for "smart" applications.
这篇综述文章旨在涵盖通过可逆加成-断裂链转移(RAFT)聚合合成线性ABC型三嵌段三元共聚物和星形聚合物的最新进展,以及它们在水溶液中的自组装性质。RAFT聚合受到了广泛关注,因为它是一种通用技术,与多种功能单体和反应条件兼容,同时能对最终结构提供出色而精确的控制,具有明确的侧基和聚合后工程潜力。线性三嵌段三元共聚物的合成可以产生非常有趣的新想法,因为刺激/非刺激和亲水/疏水单体有无数种组合可供使用。它们最有趣的特征之一是,根据其聚合度(DP)、嵌段组成、溶解方案、内部和外部刺激,它们普遍具有在不同纳米结构中自组装的能力。另一方面,星形聚合物表现出更稳定的纳米结构,具有独特的交联核心和臂嵌段,这些臂嵌段也可以包含用于“智能”应用的刺激响应嵌段。
