Dynamic Mechanical Thermal Analysis of High Density Polyethylene Reinforced with Nanodiamond, Carbon Nanotube and Graphite Nanoplatelet
Present work reports on Dynamic Mechanical Thermal Analysis (DMTA) of HDPE reinforced with surface modified 0D (Nanodiamonds-NDs), 1D (Multi Walled Carbon Nanotubes-MWCNTs) and 2D (Graphite nanoplatelets-GNPs) nanofillers. Composite samples were prepared using twin screw injection moulding machine. Dynamic properties like storage, loss modulus and tan delta were investigated as a function of temperature and at constant oscillation of 1 Hz. Optimum properties were exhibited by 0.1 CNT/HDPE during a temperature swept from 30 to 110 oC. The storage modulus and loss modulus of 0.1 CNT/HDPE increased by 57 and 28% on comparison with pure HDPE. 0.1 CNT/HDPE exhibited highest ascent during tan delta evaluation confirming good damping property. TEM analysis was carried out to investigate the morphology of ND, MWCNT and GNP.
