Multiwalled carbon nanotube pretreatment to enhance tensile properties, process stability, and filler dispersion of polyamide 66 nanocomposites

Multiwalled carbon nanotube-dispersed polyamide 66 nanocomposites (PA66/MWCNTs) were fabricated by melt-mixing pretreated MWCNTs and PA66, and the effects of pretreating techniques and types of pretreating materials were investigated. The non-fluffy method (NFM) and the dry-coating method (DCM) were studied to determine the effects of pretreatment techniques. The tensile properties were enhanced by the NFM. However, the DCM improved the...
