Dec 1, 2010 · In this article, we present a thermodynamic model for physical gels that considers both the elastic properties of the network and the transient nature of the cross-links. The cross-links’ reformation is captured through a connectivity tensor M at the microscopic level.

A gel is a semi-solid that can have properties ranging from soft and weak to hard and tough. [1][2] Gels are defined as a substantially dilute cross-linked system, which exhibits no flow when in the steady state, although the liquid phase may still diffuse through this system. [3]

Some physical hydrogels have found interesting applications. For example, Mehyar et al. investigated two physical hydrogels (one based on hydrogen-bonded starch and the other based on calcium alginate, with ionic interactions) as possible substrates for antimicrobial agents.

Presenting a unique perspective on the state-of-the-art of physical gels, this interdiscipli-nary guide provides a complete, critical analysis of the field and highlights recent developments.

In this review we consider and compare the structures and properties of a range of gels that have been studied in recent years. In comparing these gels we highlight the importance of key structural parameters in defining gel mechanical properties.

Sep 1, 1999 · In this work, we present a new approach using analytical and optical techniques in order to determine the physical and chemical properties of silica gel, as well as the measurement of the pore...

Physical gels are characterized by dynamic cross-links that are constantly created and broken, changing its state between solid and liquid under influence of environmental factors.

Apr 5, 2025 · As described before, PAM gel with 0% chemical crosslinking density is a physical gel obeying the hierarchical dynamics of non-diffusive stretched exponential decay (Fig. 2d), while PAM gel with 1% ...

Aug 8, 2018 · A physical gel is a three-dimensional (3-D) polymer organize that is held together through physical tangle, hydrogen bonds, and additionally hydrophobic interactions (Buwalda et al. 2014; Yu and Ding 2008). Physical gels are affected by environmental factors.
