Thermal Stability of Organic-Inorganic Composites Based on Dimethacrylate-Tetraethoxysilane System

Abstract

Abstract. 1 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. Values of characteristic parameters of studied organicmineral composites were calculated as the result of thermomechanical analysis of obtained curves. The composite MGF-9:TEOS = 90:10 (vol %) was found to have the maximal thermal resistance and improved thermomechanical properties.

“…When using thermal analysis it is possible to investigate a thermal stability of the compound and get a clear idea of the nature of the processes that take place during heating [19]. The results of thermal analysis are presented in the form of thermograms (Figs.…”

BIOSYNTHESIS AND CHARACTERISTICS OF METABOLITES OF Rhodococcus erythropolis AU-1 STRAIN

“…The heating rate was 5°С/min. The average weight of the samples was 80 mg, the reference substance was aluminum oxide (Khovanets' et al, 2017).…”

“…Thermal analysis is important method used to study organic and inorganic compounds. It is used to analyze thermal stability of substances as well as to obtain visualization of the nature of processes that proceed upon heating (Khovanets' et al, 2017). The results of the samples of obtained metabolites of R. erythropolis Au-1 under investigation produced by the complex thermogravimetric, differential thermogravimetric, and differential thermal analyses are given as thermograms in the figure 6.…”
