The POSS phases separation and self-assembly afforded in situ nanocubes with average diameters ranging from 25nm to 500nm. The influence of 5.3wt.% POSS on the thermal, mechanical and morphological PMMA nanocomposite properties was investigated. POSS mediated nanocube formation was accompanied by improvements of PMMA glass temperature and toughness. Depth profiling by means of ion beam Rutherford backscattering (RBS) analysis indicated the accumulation of POSS1 at the PMMA surface.
