liuosedisilaniaatio

Liuosedisilaniaatio is a term used in materials chemistry to describe a two-stage approach that combines dissolution or swelling of a silicon-containing substrate with subsequent silanization to introduce organic or organosilicon functionality. The word is derived from Finnish elements meaning “solution” and “disilanylation,” and in practice it denotes a strategy for surface modification or preparation of silicon-based materials.

In typical interpretations, the process begins with exposing silica- or silicate-based materials to a solvent system that promotes partial dissolution or formation of reactive silanol or silanolate species on the surface. A silane coupling agent, often a trialkoxysilane or related organosilane, is then added to react with these surface functionalities. The result is the formation of Si–O–Si linkages and the grafting of organic groups onto the surface, yielding functionalized particles, coatings, or thin films. The approach can improve dispersion, compatibility with organic matrices, or provide specific reactive handles for further chemistry.

Applications encompass functionalized silica nanoparticles for catalysis or sensing, surface-modified silica coatings, and the creation of hybrid materials with tailored interfacial properties. The terminology and exact procedures can vary between laboratories, and “liuosedisilaniaatio” is not universally standardized; it may be described in broader terms as a solution-mediated silanization strategy or as part of sol–gel–based surface modification.
