Multiwall carbon nanotube (CNT)-filled high density polyethylene (HDPE) nanocomposites were prepared by extrusion and considered for their suitability in the offshore sheathing applications. Transmission electron microscopy was conducted to analyse dispersion after bulk extrusion. Monolithic and nanocomposite samples were subjected to accelerated weathering and photodegradation (carbonyl and vinyl indices) characterisations, which consisted of heat, moisture (seawater) and UV light, intended to imitate the offshore conditions. The effects of accelerated weathering on mechanical properties (tensile strength and elastic modulus) of the nanocomposites were analysed. CNT addition in HDPE produced environmentally resilient nanocomposites with improved mechanical properties. The energy utilised to extrude nanocomposites was also less than the energy used to extrude monolithic HDPE samples. The results support the mass substitution of CNT-filled HDPE nanocomposites in high-end offshore applications.

Polypropylene can be improved an electrical conductivity by addition of carbon and multiwall carbon nanotube (MWCNT) as well as combination with copper (Cu) powder. Multiwall carbon nanotube used from 0.1 wt%, 0.5 wt% to 1 wt% while the addition of Cu powder into PP/C was various from 0.1 wt%, 0.2wt% to 0.5wt% respectively. This research focuses on material design of composite based on polymer and carbon to improve an electrical conductivity according to electrical conductivity requirement for bipolar plate. Bipolar plate is one of the components in PEMFC constituted a crucial component that collects and transfers electron from the anode to the cathode, therefore it should possess high electrical conductivity. The main discussion in this research is to analyze the role of multiwall carbon nano tube (MWCNT) and copper on electrical conductivity of polymer composites produced. Functional groups analysis using Fourier Transform Infrared Spectroscopy (FTIR) was also carried out to investigate whether carbon has been mixed perfectly within polypropylene. It is found that the effect of adding a small amount of MWCNT and Cu have improved their electrical conductivity of composites up to 15.62 S/cm.
