Application of Taguchi Method to Improve Resistance Quality of Graphene/Polypropylene Composites

Abstract:

Polypropylene is a widely used thermoplastic with high impact resistance and strong mechanical properties. Graphene has exhibited in a new generation of electronic component materials owing to its high thermal conductivity and low resistivity. In this study, a composite of graphene and polypropylene for injection molding purposes was created. In Taguchi method, an L9 orthogonal array for injection molding experiments was adopted. The process parameters included injection temperature (A), holding time (B), injection pressure (C), and graphene ratio (D). Optimal parameter combinations were determined according to resistivity, and the results were A3B2C1D3: 2956.333 MΩ by original and A1B2C1D3: 2802 MΩ Taguchi analysis, respectively, where the improvement was 5.2%.
