Feasibility Study of Thermoplastic nanocomposites for ESD Applications Using Additive manufacturing

Sagar V. Naval, Jitendra Tate, Harish Kallagunta


This research aims at developing a polyamide 6 nanocomposite with good combination of electrical resistivity and structural integrity that can be utilized for electrostatic discharge applications. Polyamide 6 modified with 3wt%, 5wt% and 7wt% graphene nanoplatelets (NGP) were melt blended using a co-rotating twin screw extruder and filaments of size 1.75mm were obtained. The specimens were printed using fused deposition modelling technique according to standards for electrical resistivity and tensile properties. A fair amount of dispersion and exfoliation were observed in SEM images. At 7wt% loading both the electrical resistivity and tensile properties are enhanced. In addition to as printed sample testing, annealing was performed on the test samples. Heat treatment of samples after printing was proven effective on the properties obtained.
