Two-point probe conductivity measurements of consolidated CF-PEEK control and graphene enhanced samples. In plane measurements improved from 6.7 × 10− 4 ± 3.7 × 10− 4 Scm− 1 to 0.008 ± 0.0016 Scm− 1 and through thickness measurements improved from 0.0012 ± 2.4 × 10− 5 Scm− 1 to 0.0037 ± 7.2 × 10− 4 Scm− 1. Error bars represent 95% confidence interval of the mean
