Dielectric and Electrical Properties of Poly (?-Caprolactone)/ Organomodified Clay Bionanocomposites Prepared in Open Air by in Situ Polymerization
Abstract
<jats:p>Dielectric and electrical properties of bio-nanocomposites based on poly (?-caprolactone) (PCL) with different amounts of organomodified montmorillonite clay (MMT-ODA) were investigated by broadband dielectric spectroscopy in the frequency range from 1Hz to 1MHz and in the temperature range from -100 to 25°C. These nanocomposites were prepared by in situ Ring Opening polymerization of ?-caprolactone in open air by using titanium alkoxide as a catalyst. Due to the semicrystalline structure of PCL, the high number of modes and its overlap, the relaxation patterns observed on dielectric spectra were complicated. These relaxation data were modeled using the H-N empirical equation with the contribution of conductivity. The local dynamics of PCL were unaffected by the increase of nano-clay amount, in agreement with the DSC values of glass transition temperature. The PCL/MMT-ODA 3 wt% exhibited the lowest value of dielectric strength, indicating the strongest adhesion between PCL matrix and organo-modified clay. As for PCL/MMT-ODA 5 wt%, the presence of agglomerate made the adhesion between PCL and MMT-ODA very weak. The obtained findings were congruent FTIR and XRD results. The electrical conductivity of PCL was analysed according to the Jonscher’s law. The obtained exponent s values referred to three models corresponding to different temperature ranges.</jats:p>
