PCL's water contact angle is 70.3 o , as expected from a relatively hydrophobic polymer and this result is in close agreement with the literature. Surprisingly, the contact angle of PEDOT is 36.7 o , which shows that the photochemically synthesized PEDOT showed hydrophilic behavior rather than hydrophobicity. The weak hydrophilicity is attributed to the dopant ions (bromide) present on PEDOT units, which can strongly interact with water molecules through ion-dipole interactions. This behavior was previously observed in studies regarding PEDOT: PSS (polystyrenesulfonate) due to the interaction of sulfonate ions with water molecules . PEDOT-PCL's contact angle is calculated 54.7 o , which is between PCL and PEDOT's contact angles. The final wettability of the scaffold is ideal for most of the TErelated applications.
