Dielectric Spectroscopy
( Elsevier , 2017 , Book chapter)In this chapter, an attempt has been made to review dielectric spectroscopy (DS) as a technique for the characterization of nanomaterials. DS involves the study of the response of a material to an electric field, which ... -
Molecular scale cure rate dependence of thermoset matrix polymers
( Elsevier B.V. , 2016 , Article)This manuscript demonstrates the molecular scale cure rate dependence of di-functional epoxide based thermoset polymers cured with amines. A series of cure heating ramp rates were used to determine the influence of ramp ... -
Polymer chain dynamics in epoxy based composites as investigated by broadband dielectric spectroscopy
( Elsevier B.V. , 2016 , Article)Epoxy networks of the diglycidyl ether of bisphenol A (DGEBA) were prepared using 3,3′- and 4,4′-diaminodiphenyl sulfone isomer crosslinkers. Secondary relaxations and the glass transitions of resultant networks were probed ... -
PVA/chitosan/silver nanoparticles electrospun nanocomposites: Molecular relaxations investigated by modern broadband dielectric spectroscopy
( MDPI AG , 2018 , Article)In this study, we used broadband dielectric spectroscopy to analyze polymer nanofibers of poly(vinyl alcohol)/chitosan/silver nanoparticles. We also studied the effect of incorporating silver nanoparticles in the polymeric ... -
Secondary chain motion and mechanical properties of γ-irradiated-regenerated cellulose films
( Wiley-VCH Verlag , 2017 , Article)Regenerated cellulose films prepared using NaOH/urea solvent system were exposed to different doses of γ-radiation, ranging from 5 to 50 kGy to modify their properties. Change in relative crystallinity as a function of ...
