A well-dispersed phase of exfoliated graphene oxide (GO) nanosheets was initially prepared in water. This was concentrated by centrifugation and was mixed with a liquid epoxy resin. The remaining water was removed by evaporation, leaving a GO dispersion in epoxy resin. A stoichiometric amount of an anhydride curing agent was added to this epoxy-resin mixture containing the GO nanosheets, which ...

Full recovery of interfacial bond strength after complete fiber/matrix debonding is achieved with a microencapsulated solvent-based healing chemistry. The surface of a glass fiber is functionalized with microcapsules containing varying concentrations of reactive epoxy resin and ethyl phenylacetate (EPA) solvent. Microbond specimens consisting of a single fiber and a microdroplet of epoxy are te...

We wanted to examine the effect of antigen retrieval on epoxy sections where the tissue had been infiltrated by resin containing moderately increased amounts of accelerator. The concentration of accelerator DMP-30 (Tri(Dimethyl Amino Methyl) Phenol) was varied in the range of 0% to 4% in the infiltration step of the tissue processing. Some of the epoxy sections were fixed in osmium tetroxide, a...

Visibly highly transparent indium tin oxide (ITO)/epoxy nanocomposites were prepared by dispersing polyglycidyl methacrylate (PGMA) grafted ITO nanoparticles into a commercial epoxy resin. The oleic acid stabilized, highly crystalline, and near monodisperse ITO nanoparticles were synthesized via a nonaqueous synthetic route with multigram batch quantities. An azido-phosphate ligand was synthesi...

The epoxy resin market is faced with an ever increasing demand for a “designer” range of properties for the epoxy end-use products. Therefore, it is necessary to obtain a complete mechanism and accurate kinetic model that has predictive capabilities. This dissertation addresses the issue in two sections. The first section is an analysis of systematic theoretical studies on the mechanisms of fou...

The current essay analyzes the anti-corrosion properties of epoxy primers including anti-corrosion pigment calcium hydrogen orthophosphate and hydrophobic nano silica with various percentages optimized by Taguchi experimental design. The impact of influential factors such as the percentage of anti-corrosion pigments, percentage of nano silica and pigment to binder ratio on anti-corrosion proper...

AIM To compare and evaluate few physical properties of epoxy resin, resin-modified gypsum and conventional type-IV gypsum die material. MATERIALS AND METHODS In the present study, dimensional accuracy, surface detail reproduction and transverse strength of three die materials like epoxy resin (Diemet-E), resin-modified gypsum (Synarock) and conventional type-IV gypsum (Ultrarock) are analyzed...
