1. The discovery of the volume phase transition of gels in 1978 marked the beginning of a new era in the science and technology of gels.
2. The theory of the volume phase transition of gels is constructed on the basis of analogy with the liquid–gas transition of a van der Waals gas, where the gas phase and the liquid phase correspond to the swelling state and the collapsed state of gel, respectively.
3. This Special Issue aims to revisit the volume phase transition of gels in marking a possible second beginning of a new era in the science of gels.
The article is written by experienced professionals in their field and provides an overview on current research related to volume phase transitions in gels. It is well-structured and provides clear information about its purpose, scope, and content.
