A systematic study of a number of silica materials - silica gels, mesoporous molecular sieves, hydrophobized using different approaches, polymethylsiloxanes and products of their modification, as well as hydrophobic porous coordination polymers - coordination compounds consisting of metal ions and anionic organs is carried out. A method of obtaining hydrophobic materials based on MCM-41 silica molecular sieves modified with hydrophobic alkyl fragments (methyl and n-octyl) different in length is developed. Methods of obtaining hydrophobic porous materials - hydrophobized silica gel with high surface fill with immobilized n-octyl and methyl groups and porous coordination polymers of ZnII, AlIII, CoII on the basis of 2-methylimidazolate, 2-ethylimidolate or 1,4-ftalate, are optimized. The hydrophobicity of the obtained silica materials is ensured by the presence of alkyl groups on their surface, and porous coordination polymers by the placement of groups with C – H bonds in the pores. It is shown that the obtained materials are characterized by high hydrolytic stability, which is important for their practical use as working bodies of dampers and devices for extinguishing shock loads.
The investigated substances were characterized by methods of X-ray phase analysis, which allowed to confirm their structure and phase purity, as well as to investigate the stability with prolonged contact with water.
