在合成技术进步以及加工和表征方法能力的推动下，多刺激响应（MSR）聚合物提供了具有重大社会影响的技术机会。这个观点的目的不是列举每一个可能的MSR聚合物系统，而是强调最近的进展沿着当前和未来的趋势，重新定义现代聚合物科学。在时空和能量需求的背景下，这种观点探讨了由组成，结构和层次大分子排列驱动的多刺激响应，其中多刺激可以通过结合机械响应，pH值变化，电磁辐射，磁场/电场，氧化还原反应，湿度和温度变化，溶剂和气体，或生物触发的响应来实现。多刺激反应可能是正交的，竞争性的，或协同作用的，并在开发具有信号和通信的聚合物，用精确定义的序列编码表型特性，可编程的组装/拆卸和识别属性中重新定义的原则，MSR材料将为下一代巧妙的技术进步铺平道路。
Driven by synthetic advances combined with the ability of processing and characterization methods, multi-stimulus responsive (MSR) polymers offer technological opportunities with significant societal impacts. The purpose of this perspective is not to itemize every possible MSR polymer system but instead to highlight recent advances along with current and future trends that redefined modern polymer science. In the context of spatiotemporal and energetic requirements, this perspective explores multi-stimulus responses driven by compositional, structural, and hierarchical macromolecular arrangements, where multi-stimulus may be achieved by combining mechano-responsiveness, pH changes, electromagnetic radiation, magnetic/electric fields, redox reactions, humidity and temperature changes, solvents and gases, or biologically triggered responses. Multi-stimulus responses may be orthogonal, competitive, or synergistic and governed by the redefined principles in developing polymers with signaling and communications, encoding phenotypic properties with precisely defined sequences, programmable assembly/disassembly, and recognition attributes, and MSR materials will pave the next generations of ingenious technological advances with living-like attributes.
