Аннотация Sol-gel synthesis of filled aluminosilicates with macromolecules having a dendrimer morphology (Mcalc ≈ 480000) was developed. The software package Gaussian B3LYP/6-31G(d) was used to assess the possible mechanism by which nuclei of dendrimer molecules are created, with the subsequent generation of crowns of branched ensembles capable of accommodating up to 80 wt % nano-AlOOH as a filler. The data furnished by transmission electron microscopy of the samples are in agreement with the suggested mechanism of generation and growth of dendrimers. The main results were obtained on fi lledaluminosilicate samples that contain 80 wt % nano-AlOOH and exhibit a high wear resistance in tribological tests.
