High-density polyethylene/carbon nanotubes composites: Investigation on the factors responsible for the fracture formation under tensile loading

Different concentrations (0.1, 0.2, 0.5, and 1 wt%) of OH-functionalized carbon nanotubes (CNTs) were used to prepare high-density polyethylene (HDPE) based composites via melt blending in the presence of a maleinized polyethylene (PE-g-MA) as a coupling agent. The mechanical behaviour of the produced HDPE/CNT composites was investigated in view of their possible application as reinforced materials in the civil structures and understood in terms...
