Special Issue Information

Dear Colleagues,

As we continue to explore the potential of advanced materials, smart polymers have emerged as one of the most exciting areas of research, with applications spanning various industries such as biomedical engineering, electronics, and environmental sustainability. Smart polymers, characterized by their ability to respond to external stimuli—such as pH, temperature, light, or magnetic fields—hold immense promise in revolutionizing material science.

The design and development of smart polymers have been driven by the need for materials that can perform complex functions, such as self-healing, shape memory, or controlled drug release. These materials are up-and-coming in areas where traditional polymers fall short, offering enhanced performance and new functionalities. From biomedical devices that respond to physiological conditions to adhesives that can be switched on and off with precision, smart polymers are at the forefront of materials science innovation.

In light of the growing interest and rapid advancements in this field, we are pleased to announce a Special Issue on “Smart Polymer: New Design and Applications”. This issue aims to bring together cutting-edge research and comprehensive reviews on the latest developments in smart polymer science. We invite academics, researchers, and industry professionals from around the world to contribute their work and insights to this exciting area of study.

This Special Issue welcomes contributions on a wide range of topics, including but not limited to the following:

  • Design and synthesis of stimuli-responsive polymers;
  • Characterization of responsive behavior and underlying mechanisms;
  • Development of smart interfaces and surfaces;
  • Switchable adhesives and their practical applications;
  • Innovative uses in biomedical devices, drug delivery systems, sensors, and actuators;
  • Advanced processing techniques for fabricating smart polymer materials, such as 3D printing, electrospinning, and film casting.

We encourage submissions that explore various types of smart polymers, such as thermoresponsive, pH-responsive, light-responsive, and electrically responsive materials. Contributions may also focus on hybrid systems, nanocomposites, or polymer blends that incorporate smart functionalities. Additionally, studies on the theoretical modeling of responsive behavior, as well as experimental validations, are highly welcome.

The scope of this Special Issue is deliberately broad, aiming to capture the diversity and innovation in the field of smart polymers. We are particularly interested in contributions that demonstrate novel design strategies, elucidate fundamental mechanisms, or showcase groundbreaking applications that push the boundaries of what is possible with these remarkable materials.

We look forward to your submissions and to fostering a rich dialogue on the future of smart polymers.

Catalytic coacervates, or droplet reactors, represent a forefront research area in chemistry and materials science. Despite advancements in this field, challenges persist in achieving liquid–liquid phase separation (LLPS) droplet compartmentalization and site-specific reactant recruitment/localization for reaction catalysis, similar to those within biological systems. Herein, we describe the catalytic coacervates for aqueous photo-RAFT in dilution, focusing on the site-specific recruitment/localization of ionized monomer with the aid of macromolecular crowding and confinement. Cooperative hydrogen-bonded interpolymer complexation (IPC) of imidazolium-copolymers initiates the ion-cluster formation. Further hierarchical inter-cluster complexation (ICC) leads to the LLPS droplet compartmentalization into charged dense-phase and neutral dilute-phase compartments. Site-specific recruitment and localization of the oppositely charged monomer into dense-phase compartments are achieved by salt-bridging molecular recognition. “Substantial DMA-dilution” (that is, macromolecular crowding) results in sustainable dense-phase catalytic sites within dilute-phase crowding surroundings, enabling reaction catalysis in dilution (<2% w/w monomer) to 97% conversion in 12 min. These findings underscore the key roles of macromolecular crowding and confinement in the tailorable LLPS droplet compartmentalization and also the site-specific reactant recruitment/localization essential for enzyme reaction catalysis, and provide practical guidelines for creating catalytic coacervates towards lifelike reaction functions.
