«Morphology, Strength, Thermal and Chemical Stability of Epoxy Resin-Based Nanosystems with Pyrogenic Nanosilica A-300 and Its Compacted Analogue ‘Densil’ (with Original and Modified Surface)»
0071–0090 (2021)

PACS numbers: 62.23.Pq, 68.37.Hk, 68.37.Ps, 68.55.J-, 81.05.Lg, 81.70.Pg, 82.35.Np

Compositions of epoxy resin with pyrogenic ‘Aerosil A300’-type nanosilica in its unmodified, compacted (‘Densil’) and surface-modified with silver iodide forms have been experimentally investigated. ‘Densil’ has been shown to have several times lower densification capacity (at 31–33 wt.%; for A300, it is of 12 wt.%). At the same time, it usually does not reduce the strength characteristics of the polymer epoxy composite. Moreover, in some cases, they are strengthened (adhesion, strength and elastic modulus in bending, elastic modulus in compression, and resistance in high vacuum). Microscopy revealed significant differences in the morphology of the composites with A-300 and ‘Densil’. They are manifested in a more even distribution of ‘Densil’ that is expressed in smaller quantities and smaller agglomerates. As shown, the resistance to thermooxidative degradation does not change with the addition of ‘Densil’, but increases with the addition of nanosilica A-300 or ‘Densil’ + AgJ. The introduction of ‘Densil’ and ‘Densil’ + AgJ increases the resistance to swelling and degradation in an aggressive acetone solvent, while the silica A-300 does not change it. The results of the experiments indicate the promising technology for fabrication of nanomaterials with silica A-300 and ‘Densil’ to create coatings, adhesives or compounds for industrial restoration needs.

Keywords: epoxy composite, A-300 nanosilica, ‘Densil’, compressive strength, bending strength, adhesion to steel, elastic modulus, resistance to thermal degradation, swelling
