The reinforcing effect of graphene nanosheets on the cryogenic mechanical properties of epoxy resins
The reinforcing effect of graphene in enhancing the cryogenic tensile and impact properties of epoxy composites is examined at a weight fraction of 0.05–0.50%. The micro-structure and cryogenic mechanical properties of the graphene/epoxy composites are investigated using scanning electron microscopy, transmission electron microscopy, small-angle X-ray scattering and mechanical testing tech...

Studies on the Thermal Properties of Epoxy Resins Modified with Two Kinds of Silanes
Dimethyldiethoxysilane (DMDES) and diphenyldimethoxysilane (DPDMS)-containing epoxy resins were synthesized by dehydration polycondensation. The chemical structures were determined by FT-IR, 1H NMR, and 13C NMR. The cured samples, with 4, 4''''-diaminodiphenylmethane (DDM) as curing agent, were investigated by differential scanning calorimetry (DSC), dynamic mechanical analysis (DMA), thermograv...

Mechanical and thermal properties and morphology of epoxy resins modified by a silicon compound
A silicon compound (GAPSO) was synthesized to modify the diglycidyl ether of bisphenol-A (DGEBA). The chemical structure of GAPSO was confirmed using FT-IR, 29Si NMR and GPC. The mechanical and thermal properties and morphologies of the cured epoxy resins were investigated by impact testing, tensile testing, differential scanning calorimetry and environmental scanning electron microscopy. The impa...

The preparation and properties study of methoxy functionalized silicone modified epoxy resins
ABSTRACT: In this work, a series of siloxane epoxy resins (E3074) were synthesized through reaction of poly(methylphenylsiloxane) (DC-3074) with epoxy resin. The chemical structure of the resultant epoxy resin was determined by FTIR, GPC, and epoxy equivalent weight (EEW) tests. The mechanical measurements indicated that the tensile strength of E3074 was lower than that of neat epoxy&nbs...

58. Synthesis of CdS nanocomposites using macroporous ion-exchange resins
The preparation and characterization of nanocomposites composed of CdS nanocrystals in cross-linked polystyrene matrix were reported. The used matrix was commercial macroporous ion-exchange resins. Characterizations using transmission electron microscopy (TEM) and X-ray diffraction (XRD) show the nano-sized CdS crystals with an average size of about 9 nm. These nano-sized crystals can sh...

Effect of chemical structure on the water sorption of amine-cured epoxy resins
In this investigation, water sorption behaviour of six epoxy systems with different chemical structure of amines and epoxies were monitored at five temperatures ranging from 35 to 75 °C. The sorption process was analyzed by gravimetric measurements, positron annihilation lifetime spectroscopy (PALS), and attenuated total reflection Fourier transform infrared spectroscopy (ATR-IR). PALS me...
