Resinsgels

Resinsgels are gel-like networks formed from crosslinked resin polymers that can absorb and retain liquid while maintaining a solid, three-dimensional framework. They may derive from synthetic resin systems such as acrylates, epoxies, or siloxanes, or from natural or modified resinous materials that have been polymerized and crosslinked to form a network. The term often overlaps with “gel-type resins” used in chromatography, but resinsgels broadly describe any resin-based gel network.

Preparation and structure stem from polymerization and crosslinking reactions that create a three-dimensional lattice. The degree of crosslinking and the nature of the monomer or resin determine pore size, swelling behavior, mechanical strength, and chemical stability. Pore structures can be macroporous, gel-type (more uniform and finer pores), or macroreticular (larger, irregular pores). Swelling behavior varies with solvent condition, temperature, and crosslink density, influencing transport of solutes through the network.

Properties typical of resinsgels include chemical resistance, dimensional stability, and tunable permeability. Their hydrated or swollen state provides a soft, porous matrix that can accommodate liquids or dissolved species while resisting dissolution.

Applications span chromatography (as ion-exchange, affinity, or size-exclusion resins), drug delivery and biomedical engineering (hydrogels derived from resin systems), coatings and composites, and environmental remediation (adsorption of contaminants). In research, resinsgels are used to study diffusion, swelling, and network mechanics in crosslinked polymers.

Terminology can vary, and some literature uses “gel-type resins” or “resin gels” to describe related but distinct materials depending on pore structure and intended use.
