An analytical study was performed to examine the mechanical behavior of polysilsesquioxane (PSQ) structures with the incorporation of elongation additives. The PSQ structures are commonly categorized as ladder, cage (polyhedral), or random structures depending on the synthesis method..The mechanical behavior of macroscopic results, as determined by simple pencil hardness testing, was analyzed and studied with consideration of the unique characteristics of nano-sized materials. To investigate further, various techniques such as AFM-based morphology analysis, force modulation microscopy (FMM), and nanoidentation analysis were employed. Notably, FMM mode analysis revealed distinctive structural maintenance characteristics in the cage structure with an elongation linker, as observed through morphology and amplitude mode analysis. Nanoindentation analysis also confirmed that this aggreated-structure differs from the plain structure, with improved structural maintenance properties leading to enhanced protective capabilities
