In order to expand the range of materials that can be used in outer space and in development of small spacecraft, ladder polyphenylsilsesquioxanes with different molar weights and the Nb-siloxane composites based on them were studied. The properties of the polymer films were studied, including tests in an oxygen plasma flow. Both initial and filled ladder polymers feature extremely low erosion coefficients in the region of 10 cm/atom O at a high fluence of atomic oxygen of 1.

- The study explored nanocomposites made from organosoluble polyimide and branched metallosiloxane oligomers containing various metal atoms (Al, Cr, Fe, Zr, Hf, Nb) to understand their structure and thermal properties.
- The relationship between nanoparticle geometry, thermal properties, and resistance to oxygen plasma erosion was not straightforward, indicating that filler composition and metal type significantly affect the material's durability.
- The effectiveness of nanoparticles as protective elements was assessed by measuring erosion yields, allowing for efficient comparisons of different nanosize fillers for developing coatings suitable for space applications.
