The specific interactions between the polymer chains and the solvent molecules determine the final rigidity, elasticity, and stability of the resulting gel. Performance and Functionality The materials used are engineered to provide specific functional properties.
Understanding the Chemistry of Fragile Tough Gels
Oil-Based Gels The choice of liquid component dictates whether a gel is classified as water-based or oil-based. The liquid, which can be water, oil, or another solvent, gives the gel its fluidity and bulk.
Without this liquid component, the solid matrix would simply be a dry sponge or a brittle solid. These cross-links are the critical bridges that create the three-dimensional network capable of holding the liquid in place.
Understanding the Chemistry of Fragile Tough Gels
These polymers can be naturally occurring, such as cellulose or gelatin, or synthetic, like polyethylene glycol or polyacrylamide. For these polymers to form a stable gel rather than a simple liquid solution, they must be linked together at various points by cross-linking agents.

Looking at What are gels made of from another angle can help expand the discussion and give readers a second clear paragraph under the same section.
More perspective on What are gels made of can make the topic easier to follow by connecting earlier points with a few simple takeaways.
