sol-gel system

One of the promising directions for production of advanced materials is creation of hybrid organic-inorganic nanocomposites that demonstrate not only the improved properties of organic matrix, but also the emergence of the new specific properties due to the presence of inorganic component. Hybrid organic-inorganic materials can be synthesized by sol-gel method as a result of sol-gel process involving organic-inorganic precursors. Nowadays sol-gel technique is considered as a simple and an ecologically friendly method of nanocomposite syntheses.

The influence of composition of hybrid organic-inorganic composites based on oligoesteracrylate (MGF-9)−tetraethoxysilane (TEOS) system on their thermal properties and molecular structure was investigated. Thermograms and curves of thermal destruction of samples were obtained, from which temperature ranges, weight loss of samples and thermal effects of each stage were defined. It is shown that introducing an inorganic filler into polymer matrix promotes increasing of thermal stability of the material.
