Abstract

Octamethyl-POSS−HDPE nanocomposites were prepared by the melt mixing route. The rheological and viscoelastic behavior of HDPE−octamethyl-POSS nanocomposites was investigated with a strain-controlled rheometer and dynamic mechanical analysis (DMA). The rheological results show that while at lower filler concentration (0.25−0.5 wt %) POSS particles act as lubricant and reduce the complex viscosity of the nanocomposites, at higher concentrations, viscosity increases. POSS remains miscible in HDPE at lower concentrations and lower temperatures used in the study; however it starts aggregating at higher concentrations and higher temperatures. The presence of POSS particles causes gelation in HDPE matrix at concentrations higher than 5 wt % possibly due to the segregated particle−particle interaction. The storage modulus shows an increase at lower POSS concentrations but decreases at higher POSS concentrations. The α-transition temperatures shift to higher values at low POSS concentrations and is attributed to restriction of the movement of HDPE chain segments in the intercrystalline regions due to the presence of POSS macromers around the crystallite boundaries. The effect of POSS on morphology of HDPE was studied with X-ray diffraction and DSC techniques. It was observed that while POSS does not interfere with the crystallization of HDPE, it crystallizes itself into nanocrystals.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
