The effect of different concentrations of aluminosilicate fly ash cenospheres, as well as silver-coated aluminosilicate fly ash cenospheres, on the structure and thermal properties of polymeric composites has been studied. In the scope of this work, composites based on styrene–butadiene–styrene triblock copolymer and aluminosilicate cenospheres with different ratios between components in the mixture have been studied. By using optical microscopy, it has been shown that aluminosilicate cenospheres introduced into the polymeric matrix through a solution are evenly distributed throughout the entire volume of the film, with no formation of any aggregates or agglomerates. Thermal analysis has shown that cenospheres provide an increase in the thermal resistance of composites. At the same time, the increase in the aforementioned thermal parameters is correlated to a great extent with the amount of filler. By using infrared spectroscopy, it has been shown that the IR spectra of the composites exhibit new signals corresponding to the stretching vibrations of SiO2 and metal oxides.
