2.2. Ex Situ Preparation of Castor Oil Based HBPEA/
PAni Nanofiber Nanocomposites. 2.2.1. Preparation of
PAni Nanofiber. The polyaniline nanofiber doped with HCl
was prepared following the interfacial polymerization technique
as reported by Huang et al.14 This PAni nanofiber was washed
with double-distilled water followed by methanol several times.
The nanofiber was dispersed in THF (1 g/mL) prior to its
incorporation into the polymer matrix.
