“…So far, only a handful of research works has been published on the effect of rheological parameter variation by using rheometrics system (parallel or cone plates) and capillary viscometer. [11][12][13][14][15][16] The evaluation of melt rheological properties of POM and its composites in terms of complex viscosity, storage modulus and loss modulus with angular frequency is important. However, the correlation of flexural, impact, rheology, thermal and wettability behaviors of CNT/POM is missing.…”

The paraffin oil dispersion technique innovated in the recent years to synthesize bulk polymer nanocomposite materials has a uniform dispersion. This research work aims to study the effect of added carbon nanotubes (CNTs) on flexural, impact and rheology behaviors of polyoxymethylene (POM) reinforced by 0–0.03 wt% of CNT using paraffin oil dispersion technique. The wettability and lamellar thickness were measured and rheological performance investigated using a parallel plate rheometer. The flexural and impact mechanical properties were also evaluated. The fracture surfaces were then examined by microscopy. The results showed that the energy to break, flexural strength and modulus increased proportionally with the addition of the amount of CNT in the matrix. For the rheology behavior, the viscosity decreased at the low percentage of CNT and then increased with increase in the percentage weight ratio of CNT in the POM matrix. It was also noted that the water contact angle rose with the increase the CNT percentages. Copyright © 2016 John Wiley & Sons, Ltd.
