RT Journal Article T1 Printability Study of a Conductive Polyaniline/Acrylic Formulation for 3D Printing A1 Arias Ferreiro, Goretti A1 Ares Pernas, Ana Isabel A1 Lasagabaster Latorre, Aurora A1 Aramburu Ocariz, Nora A1 Guerrica Echevarría, Gonzalo A1 Dopico García, Mª Sonia A1 Abad López, María José AB There is need for developing novel conductive polymers for Digital Light Processing (DLP) 3D printing. In this work, photorheology, in combination with Jacobs working curves, efficaciously predict the printability of polyaniline (PANI)/acrylate formulations with different contents of PANI and photoinitiator. The adjustment of the layer thickness according to cure depth values (Cd) allows printing of most formulations, except those with the highest gel point times determined by photorheology. In the working conditions, the maximum amount of PANI embedded within the resin was ≃3 wt% with a conductivity of 10−5 S cm−1, three orders of magnitude higher than the pure resin. Higher PANI loadings hinder printing quality without improving electrical conductivity. The optimal photoinitiator concentration was found between 6 and 7 wt%. The mechanical properties of the acrylic matrix are maintained in the composites, confirming the viability of these simple, low-cost, conductive composites for applications in flexible electronic devices.
