Preferred Label : gel;
IUPAC definition : lamellar structures including mesophases, e.g., soap gels, phospholipids and clays;; a covalent polymer network, e.g., a network formed by crosslinking polymer chains
or by non-linear polymerization;; a polymer network formed through the physical aggregation of polymer chains, caused
by hydrogen bonds, crystallization, helix formation, complexation, etc, that results
in regions of local order acting as the network junction points. the resulting swollen
network may be termed a thermoreversible gel if the regions of local order are thermally
reversible;; particulate disordered structures, e.g., a flocculent precipitate usually consisting
of particles with large geometrical anisotropy, such as in v2o5gels and globular or
fibrillar protein gels.; a polymer network formed through glassy junction points, e.g., one based on block
copolymers. if the junction points are thermally reversible glassy domains, the resulting
swollen network may also be termed a thermoreversible gel;; Non-fluid colloidal network or polymer network that is expanded throughout its whole
volume by a fluid.;
Scope note : corrected from previous definition where the definition is via the property identified
in note 1 (above) rather than of the structural characteristics that describe a gel.; a gel has a finite, usually rather small, yield stress.; particulate disordered structures, e.g., a flocculent precipitate usually consisting
of particles with large geometrical anisotropy, such as in v2o5gels and globular or
fibrillar protein gels.;
