Universal power law behavior of the AC conductivity versus frequency of agglomerate morphologies in conductive carbon nanotube-reinforced epoxy networks
(
John Wiley and Sons Inc.
, 2016 , Article)
The Jonscher universal power law for ac conductivity versus frequency (f = /2) in the dispersion region was tested for a multiwall carbon nanotube/epoxy nanocomposite. The effect of changes in agglomerate morphology on the ...
Heat transfer performance of paraffin wax based phase change materials applicable in building industry
(
Elsevier Ltd
, 2016 , Article)
Thermal characterization of phase change materials (PCMs) compose of linear low-density polyethylene (LLDPE), paraffin wax (W) with a melting point of 25 °C, and expanded graphite (EG), that are highly effective in thermal ...
High performance sulfonic acid doped polyaniline–polystyrene blend ammonia gas sensors
(
Springer Nature
, 2016 , Article)
In this work, we present a method of preparation and sensing measurement of four camphorsulfonic acid (CSA) doped polyaniline–polystyrene blends (PANI–PS), where PANI is obtained by dispersion polymerization and blending ...
Melt processing and properties of linear low density polyethylene-graphene nanoplatelet composites
(
Elsevier
, 2016 , Article)
Composites of Linear Low Density Polyethylene (LLDPE) and Graphene Nanoplatelets (GNPs) were processed using a twin screw extruder under different extrusion conditions. The effects of screw speed, feeder speed and GNP ...
Effect of two types of graphene nanoplatelets on the physico-mechanical properties of linear low-density polyethylene composites
(
Taylor and Francis Ltd.
, 2016 , Article)
The influence of two types of graphene nanoplatelets (GNPs) on the physico-mechanical properties of linear low-density polyethylene (LLDPE) was investigated. The addition of these two types of GNPs - designated as grades ...
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 ...
Propagation rate coefficient for sulfobetaine monomers by PLP-SEC
(
Elsevier Ltd
, 2016 , Article)
Zwitterionic polymers have been extensively used in the biomedical field, however, the knowledge about the kinetics and mechanism of radical polymerization of their monomers is limited. This work introduces the first ...

Nowadays hydrogel materials are being used in medical practice for wound dressing purposes. Hydrogel/textile composites can be formed to increase the mechanical strength and handling capability of hydrogel materials. ...
The effect of sliding speed on the wear of steel-tool steel pairs
(
Elsevier Ltd
, 2016 , Article)
This study examines the effect of sliding speed and surface temperature on the wear behavior of an unlubricated mild steel-tool steel contact pair using the pin-on-disc test. The operating conditions and contact pair are ...
