Stimuli-responsive polymers (SRPs) can change their conformations and properties by reacting to a signal that may be a change in temperature, pH or chemical composition of the surrounding, a stress, light irradiation, an electric or magnetic field and ultrasound. Holding great promises for diverse applications such as drug delivery, sensors and smart devices, SRPs represent an active research area. Our proposed program aims at developing new SRPs whose reactions to a stimulus can be controlled in a more complex and more precise manner than the systems known to date, and to gain new fundamental knowledge and understanding on the relationship between the responsiveness of a given polymer and its structure. Our basic strategy is to use rational and creative molecular and polymer designs to address a number of fundamental questions, and our studies will cover block copolymer (BCP) micellar aggregates, BCP brushes on a substrate, shape-memory polymers and optically controllable processing of BCP nanostructures. Our long-term objective is to contribute to establishing the general rules in designing SRPs for specific applications.

刺激反应性聚合物（SRP）可以通过对可能会改变周围温度，pH值或化学成分的信号，应力，光照射，电场或磁场以及超声来改变其构象和特性。 SRP对药物输送，传感器和智能设备等各种应用的巨大承诺代表了一个活跃的研究领域。我们提出的计划旨在开发新的SRP，其对刺激的反应可以比迄今为止已知的系统更复杂，更精确地控制，并获得了有关给定聚合物响应性与响应性之间关系的新的基本知识和理解它的结构。我们的基本策略是使用理性和创造性的分子和聚合物设计来解决许多基本问题，我们的研究将涵盖块共聚物（BCP）胶束聚集体，在子材料上的BCP刷子，形状 - 内存聚合物以及BCP的光学控制处理。纳米结构。我们的长期目标是为建立针对特定应用程序设计SRP的一般规则做出贡献。
