Abstract
Polymer gels are three-dimensional polymer networks swollen by solvents. They exhibit high elasticity and swellability and are widely used in many fields. The design, development, and application of these materials are all dependent on a precise understanding of molecular mechanisms of elasticity and swellability. The development of a model polymer gel system with a uniform structure and low degree of defects facilitates the test of these mechanisms. This review summarized the recent progress in understanding the local polymer/solvent interaction in determining the elasticity and swellability of the model polymer gels. A particular emphasis is placed on the relationship between the conformation of the precursor chains on a microscopic scale and the modulus and swelling ratio of polymer gels on a macroscopic scale under the influence of the polymer/solvent interaction. Knowledge of the relationship plays a vital role in the future development of novel functional polymer gel materials.
期刊介绍：
Current Opinion in Colloid and Interface Science (COCIS) is an international journal that focuses on the molecular and nanoscopic aspects of colloidal systems and interfaces in various scientific and technological fields. These include materials science, biologically-relevant systems, energy and environmental technologies, and industrial applications.
Unlike primary journals, COCIS primarily serves as a guide for researchers, helping them navigate through the vast landscape of recently published literature. It critically analyzes the state of the art, identifies bottlenecks and unsolved issues, and proposes future developments.
Moreover, COCIS emphasizes certain areas and papers that are considered particularly interesting and significant by the Editors and Section Editors. Its goal is to provide valuable insights and updates to the research community in these specialized areas.
