Web1 jan. 2014 · Once the sol has been formed, they will cross-link to form a gel structure. This formation of a gel from the sol gives the materials the name sol–gel (Fig. 3). This cross-linking is achieved through a polycondensation step. This step is the same as the condensation step, except that it results in a structure that is highly cross-linked. The gel is initially formed by the assembly of particles into a space-spanning network, leading to a phase arrest. In the aging phase, the particles slowly rearrange to form thicker strands, increasing the elasticity of the material. Gels can also be collapsed and separated by external fields such as … Meer weergeven A gel is a semi-solid that can have properties ranging from soft and weak to hard and tough. Gels are defined as a substantially dilute cross-linked system, which exhibits no flow when in the steady-state, … Meer weergeven Gels consist of a solid three-dimensional network that spans the volume of a liquid medium and ensnares it through surface tension effects. This internal network structure … Meer weergeven Many gels display thixotropy – they become fluid when agitated, but resolidify when resting.
