AFM scans (height and amplitude interval is 0.0–1.0 μm) of composites based on silica with immobilized PMPS using protocol 2. The photos illustrate the morphology of silica powders modified with PMPS by applying protocol 2 (samples 4 and 6, the modifying mixture distribution at each stage was 40/35/25 vol.% of the total amount) that are synthesized according to the schemes: “from short to long ” (S-L) 4 and “from long to short” (L-S) 6 (the ratio of PMPS/DMC in the modifying mixture at different stages of modification was 20/5.8/3.4 and 3.4/5.8/20, respectively) (Table 1)
