The sol-gel process has been known since the late 1800s; however, in the last three decades, the process has been extensively developed, enabling the preparation of new and advanced materials that are not easy to obtain using other methods.
The sol-gel technique is a versatile synthesis method used to produce glasses and ceramics at low temperatures. Sol-gel chemistry is based on the hydrolysis of metal alkoxide precursors into a water/alcohol solution, and the polycondensation of the formed oligomers, which leads to the formation of a 3D inorganic network. Therefore, the process involves the transition of a system from a mostly colloidal liquid (‘sol’) into a solid ‘gel’. By drying the obtained wet gel, it is possible to prepare xerogels (by exposure to low temperatures) or aerogels (by solvent extraction under supercritical conditions) or dense ceramic and glass by means of further heat treatment at higher temperatures.
The increasing attention given to this method is due to its versatility, which is derived from the various special shapes obtained directly from the gel state (e.g., monoliths, film, fibers, nanoparticles and monosized powders). Many parameters of the sol-gel process, indeed, can be modulated in order to control the chemical composition, microstructure, and, thus, the properties of the obtained materials. Moreover, the low processing temperatures allow to entrap thermolabile molecules (polymers, drugs, biomulecules, etc.) in the inorganic glassy matrix, making the sol-gel process an ideal technique to prepare organic–inorganic hybrid materials. The leading idea in their development is to take the advantageous properties of each component, which forms the hybrid, by trying to decrease or eliminate its drawbacks, through a synergic effect, which results in the generation of a new material with new properties.
The multidisciplinary approach of sol-gel technology, therefore, has allowed the development of materials for a wide range of applications: To produce optical fibers, optical or anticorrosive coatings, catalysts, wave guides, chemical sensors, biosensor, bioglass, and drug delivery systems.
Now potential applications of sol-gel technology are now continuously emerging into new areas of discovery.
It is my pleasure to invite you to submit a manuscript for this Special Issue. Full papers, communications, and reviews are all welcome.
