Polymerization-induced self-assembly (PISA) combines polymerization and self-assembly in a single step with distinct efficiency that has set it apart from the conventional solution self-assembly processes. PISA holds great promise for large-scale production, not only because of its efficient process for producing nano/micro-particles with high solid content, but also thanks to the facile control over the particle size and morphology. Since its invention, many research groups around the world have developed new and creative approaches to broaden the scope of PISA initiations, morphologies and applications, The growing interest in PISA is certainly reflected in the increasing number of publications over the past few years, and in this review, we aim to summarize these recent advances in the emerging aspects of RAFT-mediated PISA. These include (1) non-thermal initiation processes, such as photo-, enzyme-, redox- and ultrasound-initiation; the achievements of (2) high-order structures, (3) hybrid materials and (4) stimuli-responsive nano-objects by design and adopting new monomers and new processes; (5) the efforts in the realization of upscale production by utilization of high throughput technologies, and finally the (6) applications of current PISA nano-objects in different fields and (7) its future directions.
聚合诱导自组装(PISA)在一步中将聚合和自组装结合起来,具有独特的效率,使其有别于传统的溶液自组装过程。PISA在大规模生产方面具有巨大潜力,这不仅是因为其能够高效地生产具有高固含量的纳米/微粒,还得益于对颗粒尺寸和形态的轻松控制。自其发明以来,世界各地的许多研究团队都开发了新颖且富有创造性的方法,以拓宽PISA引发、形态和应用的范围。对PISA日益增长的兴趣无疑体现在过去几年中出版物数量的不断增加上。在本综述中,我们旨在总结可逆加成-断裂链转移(RAFT)介导的PISA新兴方面的这些最新进展。这些进展包括:(1)非热引发过程,如光引发、酶引发、氧化还原引发和超声引发;(2)通过设计并采用新单体和新工艺实现高阶结构、(3)杂化材料和(4)刺激响应性纳米物体;(5)利用高通量技术实现扩大规模生产的努力,最后是(6)当前PISA纳米物体在不同领域的应用以及(7)其未来发展方向。
