A series of silica mesoporous molecular sieves SBA-15 with a 7.7 ± 0.8 nm pore diameter, the surface of which is hydrophobized with methylsilyl groups, and polymethylsiloxane derivatives with a 1.6 ± 0.8 nm pore diameter were obtained. These sieves are characterized by X-ray phase analysis, adsorption of nitrogen at 77 K and water at 293 K, as well as IR spectroscopy. It is established that there is a significant resistance to water intrusion (absorption) only in the case of substances characterized by the nitrogen adsorption potential value ∆μ₀ ≤ 6.4 kJ/mol. The studied systems can be used as “molecular springs” in shock load damping devices due to their functional properties.

获得了一系列孔径为7.7±0.8 nm、表面经甲基硅烷基团疏水化处理的二氧化硅介孔分子筛SBA-15，以及孔径为1.6±0.8 nm的聚甲基硅氧烷衍生物。这些筛子的特征在于 X 射线相分析、77 K 下的氮和 293 K 下的水吸附，以及红外光谱。确定只有在以氮吸附电位值 ∆μ ₀ ≤ 6.4 kJ/mol为特征的物质的情况下，才具有显着的抗水侵入（吸收）能力。由于其功能特性，所研究的系统可用作冲击负载阻尼装置中的“分子弹簧”。
