Hybrid organic-inorganic gels that are melting gels
Ever since the observation in 2001 that some organic-inorganic silica hybrid gels are rigid at room temperature but soften and flow around 100 °C, there has been interest in so-called melting gels. Following heating to 150 °C or higher, the gels no longer soften and are considered consolidated hybrid glasses. The catalog of melting gels has grown over the past 20 years. Longer chain substitutions and other functional groups have been attached to the ≡Si-O-Si≡ molecular species. The substitutions make it possible to adjust the glass transition, the viscosity, and the temperature range of their usefulness.
期刊介绍：
The primary objective of the Journal of Sol-Gel Science and Technology (JSST), the official journal of the International Sol-Gel Society, is to provide an international forum for the dissemination of scientific, technological, and general knowledge about materials processed by chemical nanotechnologies known as the "sol-gel" process. The materials of interest include gels, gel-derived glasses, ceramics in form of nano- and micro-powders, bulk, fibres, thin films and coatings as well as more recent materials such as hybrid organic-inorganic materials and composites. Such materials exhibit a wide range of optical, electronic, magnetic, chemical, environmental, and biomedical properties and functionalities. Methods for producing sol-gel-derived materials and the industrial uses of these materials are also of great interest.
