Gelteknik

Gelteknik is a term that generally refers to the application of gel-like materials in engineering and technical contexts. These materials possess properties that fall between those of a solid and a liquid, exhibiting viscosity and elasticity. The specific nature of "gelteknik" depends heavily on the type of gel and its intended purpose.

Commonly, gelteknik involves the use of hydrogels, which are cross-linked polymer networks that can absorb and retain large amounts of water. These hydrogels find applications in various fields, including medicine for drug delivery and wound healing, in agriculture for soil conditioning and water retention, and in consumer products like diapers and contact lenses.

Beyond hydrogels, other types of gels, such as organogels (gels formed in organic solvents) and thermoreversible gels (gels that change their state with temperature), are also employed. In materials science, gel-based processes can be used for synthesizing novel materials with controlled pore structures and properties. The ability of gels to swell, contract, and respond to external stimuli like pH or temperature makes them versatile for smart material applications. Research in gelteknik continues to explore new gel compositions and advanced fabrication techniques to expand their utility in diverse technological areas.
