Supramolecular Polymers: Inherently Dynamic Materials

Area of Science:

• Polymer Chemistry
• Materials Science
• Supramolecular Chemistry

Background:

• Supramolecular polymers (SPs) emerged in the 1990s, initially focusing on H-bonding self-assembly.
• The field has expanded to include complex dynamic materials, encompassing both noncovalent and covalent interactions, leading to dynamic polymers (dynamers).
• Dynamers represent a paradigm shift, enabling applications from self-healing to biocompatible materials.

Purpose of the Study:

• To present the evolution of supramolecular polymer chemistry.
• To highlight the development of dynamic polymers (dynamers) and their functional properties.
• To discuss the potential of dynamers in addressing plastic recyclability challenges.

Main Methods:

• Review of supramolecular polymer chemistry evolution from linear chains to complex structures.
• Exploration of dynamic properties, including component exchange and self-healing.
• Analysis of literature examples showcasing SPs and dynamers.

Main Results:

• SPs have evolved through three overlapping periods: generation of polymeric entities, exploration of properties/applications, and investigation of dynamic properties.
• Dynamers exhibit novel functionalities like component exchange and self-healing.
• SPs have become a multidisciplinary field involving chemistry, biology, and materials science.

Conclusions:

• Dynamers, due to their inherent reversibility, offer a promising solution for plastic recycling and achieving a circular economy.
• The development of SPs has led to advanced materials with significant potential in various applications.
• SPs are crucial for creating sustainable materials and addressing environmental challenges posed by plastic waste.
