Abstract
The dispersion, morphology and crystallization kinetics of low density polyethylene (LDPE)–octakis(n-octadecyldimethylsiloxy)octasilsesquioxane (POSS) nanocomposite blends was investigated. Novel octakis(dimethylsiloxy)octasilsesquioxane (Q8M8H) molecules were octafunctionalised with octadecyl alkyl-chains (Q8C18) and blended with 0.25–10 wt% loadings into a commercial LDPE. Time-resolved Small- and Wide-Angle X-ray Scattering (SAXS/WAXS), thermal and microscopy techniques were used to elucidate the POSS dispersal, crystalline morphology and crystallization kinetics of the host polymer. POSS particles dispersed well in the host polymer up to 5% wt loading and ac...
