The induction of macroscopic changes in colour, shape, and functionality through designed nanoscale control can produce smart materials responding to chemical or physical triggers such as heat, light, electricity, pH, magnetic forces, guest molecules, and mechanical forces. These materials have attracted attention for their use in actuators, sensors, optoelectronic devices, information storage, shape memory, medical applications, intelligent or autonomous systems, and other disruptive systems.
This Collection aims to bring together the latest progress in the synthesis, characterization, understanding, and application of functional materials that integrate stimuli-responsive molecular systems.
We welcome studies across the spectrum of experimental to theoretical research, with topics of interest including but not limited to:
Synthesis of stimuli-responsive molecules, polymers, porous materials, carbon materials, soft and crystalline materials.
Mechanistic details of molecular-level stimuli responses.
Probing responses of systems at surfaces and interfaces.
Processing and integration of stimuli-responsive materials into systems and devices.
Demonstrations of molecular level stimuli-responsive materials in functions and applications.
The Collection primarily welcomes original research papers, in the form of both full articles and communications. All submissions will be subject to the same review process and editorial standards as regular Communications Materials Articles.
Understanding enzyme-response mechanisms is important for designing materials in cell therapy, biomedical research, and tissue engineering. Here, a chitosan/γ-polyglutamic acid hydrogel is designed as a platform to understand the role of gallic acid in the enzyme-response mechanism.
Mechanical grinding of crystals aids in converting photostable polymorph to a photoactive one but is not widely applied to organic polymers. Here, mechanoactivation and amorphization of photostable styryldipyrylium ionic monomers are demonstrated.
Gas-responsive polymers are unconventional smart materials that utilizes specific gases. Here, polydimethylsiloxane elastomers appended with amine groups react with CO2 leading to gas-induced mechanical reinforcement.
