After the blending of PCL and [n]CPPs as discussed above, they were loaded into 3 mL syringes (Nordson Continuum EFD) with a 25-gauge nozzle (Nordson EFD Precision Tip) and a pneumatic plunger. The loaded syringes were placed in an oven at 80 °C overnight prior to processing which was performed at 80°C with 2 bars of pneumatic air pressure. A voltage of 6.0 kV was used across a gap of 4 mm to establish an electric field of 1.5 kV.mm -1 between the charged head and grounded metal collector. The jet speed was determined at a first occurrence of the straight printed fiber when the printing speed was varied from 350 mm.min -1 to 700 mm.min - 1 , with 10 mm.min -1 steps. After determination of the CTS for blending of PCL and [n]CPPs at 630 mm.min -1 , a collector speed of 640 mm.min -1 was used to generate all planar scaffolds and structures.
