Review of chemo-responsive shape change/memory polymers

Purpose - The purpose of this paper is to examine the underlying mechanism and physico-chemical requirements of chemo-responsive shape change/memory polymers and to explore the future trend of development and potential applications. Design/methodology/approach - Working mechanism in chemo-responsive shape change/memory polymers is firstly identified. And then the physico-chemical requirements for the representative polymers are characterized. Findings - The different working mechanisms, fundamentals, physico-chemical requirements and theoretical origins have been discussed. Current research and development on the fabrication strategies of chemo-responsive shape change/memory polymers have been summarised. The future trend and potential applications have been explored and estimated. Research limitations/implications - This review examines physico-chemical requirements and theoretical origins necessary to achieve chemo-responsiveness, and then discusses recent developments and future trends. Practical implications - Shape change/memory polymers can be used in the broad field of bio- and/or medicine. Originality/value - Breakthroughs and rapid development of chemo-responsive shape change/memory polymers will significantly improve the research and development of smart materials, structures and systems.
