Abstract
This research conducted ring opening polymerization (ROP) of ε-caprolactone (C.L.) with a novel initiator, namely; Eosin Y functionalized multiwalled carbon nanotube (MWCNT) at 140 °C with nitrogen sparge under different concentrations. ROP of C.L. carried out at two different experimental conditions similar to variations in [M0/I0] and [C.L.]. Fourier transform infrared (FTIR) spectroscopy and nuclear magnetic resonance (NMR) spectroscopy confirmed the structure of MWCNT-Eosin Y initiated ROP of C.L. Gel permeation chromatography (GPC), X-ray photoelectron spectroscopy (XPS), UV-visible spectroscopy (UV-vis), scanning electron microscopy (SEM), and transmission electron microscopy (TEM) further characterized the structure. UV-visible spectroscopy determined the binding constant (K), for samples prepared under different [C.L.]. © 2010 Elsevier B.V. All rights reserved.
