Purpose – To develop a method for the preparation of multi‐walled carbon nanotube reinforced low density polyethylene (LDPE) composites (MWNTs/LDPE), based on ultrasonic vibration, solution casting and melt mixing.Design/methodology/approach – The preparation for MWNTs/LDPE composites was carried out by vibration of carbon nanotubes (CNT), solution casting and melt mixing for MWNTs and LDPE. The physical chemical properties of the composites were characterised using a variety of techniques including scanning electron microscopy, resistance and tensile measurement.Findings – It was found that the preparation method reported had significantly improved the dispersion of multi‐walled carbon nanotubes (MWNTs) in LDPE matrix, resulting in the improvement of tensile strength of the composite. The percolation of MWNTs in LDPE matrix was between 10 and 15 wt% (1016‐108 Ω cm).Practical implications – The preparation method reported addressed a problem concerning the dispersion of CNT in polymer matrix. The method d...
