Various methods of toughening the bonding between the interleaf and laminate glass fiber reinforced polymer (GFRP) have been developed due to the increasing applications in industries. A polystyrene (PS) additive modified epoxy is used to improve the diffusion and precipitation region between polysulfone (PSU) interleaf and epoxy due to its influence on the curing kinetics without changing glas...

Epoxy is a versatile resin used in different fields such as coatings, colors, colorants, and composites. Adding nano-scale fillers/additives to the epoxy has valued epoxy coatings for engineering applications, and opened the time of advanced epoxy-based nanocomposite coatings. In the present work, graphene oxide GO was chemically functionalized with starch, as a natural polymer, and added to th...

Epoxyeicosatrienoic acids (EETs), the eicosanoid biomediators synthesized from arachidonic acid by cytochrome P450 epoxygenases, are inactivated in many tissues by conversion to dihydroxyeicosatrienoic acids (DHETs). However, we find that human skin fibroblasts convert EETs mostly to chain-shortened epoxy-fatty acids and produce only small amounts of DHETs. Comparative studies with [5,6,8,9,11,...

Waterborne Epoxy based coatings were prepared by using a water-borne epoxy resin and a suitable hardener. The formulation and optimization procedure were carried out on the bases of experimental designs by the mixture design technique in which the important paint properties are modeled by using special cubic model. The corrosion behavior of these coatings was investigated using electrochemical ...

In this article, the effect of combined temperature-concentration and shear rate conditions on the rheology of double-walled carbon nanotubes (DWCNTs)/ RTM6-Epoxy suspension was investigated to determine the optimum processing conditions. The rheological behavior and cure kinetics of this nanocomposite are presented. Cure kinetics analysis of the epoxy resin and the epoxy resin filled with DWCN...

The focus of this work is the evaluation of the physical compatibility between an epoxy resin used as a matrix and an oxidized, unsized carbon fiber, and between this same epoxy resin and glassy carbon. For this purpose, carbon fibers, glassy carbon and epoxy resin have been assigned Hansen solubility (cohesion) parameters (HSP) by analysis of their interactions with a set of well-defined liqui...

Raman spectroscopy has become a powerful analytical tool providing detailed and specific information at a molecular level. This benefit together with rapidity and other features of the method yields an advantage of quasi real time monitoring and measuring the structure changes dynamics. There is no doubt that Raman spectroscopy can be ranked among powerful and useful research and analytical met...

Plasma nanocoating of allylamine were deposited on the surfaces of multi-walled carbon nanotubes (MWCNTs) to provide desirable functionalities and thus to tailor the surface characteristics of MWCNTs for improved dispersion and interfacial adhesion in epoxy matrices. Plasma nanocoated MWCNTs were characterized using scanning electron microscopy (SEM), high-resolution transmission electron micro...

Images of a hematite-based epoxy coating are obtained by scanning electron microscopy (SEM). At the scale of a few micrometers, they show aggregates of hematite nano-particles organized along thin curved channels. We first segment the images and analyze them using mathematical morphology. The heterogeneous dispersion of particles is quantified using the correlation function and the granulometry...
