The effect of epoxy-silicone copolymer content on the thermal and mechanical properties of cured epoxy resin modified with siloxane
In this research, a bisphenol-A type epoxy resin (DGEBA) was modified with epoxy-block-silicone copolymers and hydroxyl-terminated silicone oligomers by physical blending and a chemical reaction, respectively. The chemical structure of the siloxane-bridged epoxy resin terminated by –OHs was characterized by Fourier transform infrared spectroscopy (FTIR), 1H-NMR and an epoxy equivalent weight (E...

(ChemSusChem)Synthesis and Properties of a Bio-based Epoxy Resin with High Epoxy Value and Low Viscosity
A bio-based epoxy resin (denoted TEIA) with high epoxy value (1.16) and low viscosity (0.92 Pa s, 258C) was synthesized from itaconic acid and its chemical structure was confirmed by 1H NMR and 13C NMR spectroscopy. Its curing reaction with poly(propylene glycol) bis(2-aminopropyl ether) (D230) and methyl hexahydrophthalic anhydride (MHHPA) was investigated. For comparison, the commonly used dig...

Grafting of epoxy chains onto graphene oxide for epoxy composites with improved mechanical and thermal properties
Epoxy composites filled with both graphene oxide (GO) and diglycidyl
ether of bisphenol-A functionalized GO (DGEBA-f-GO) sheets were prepared at
different filler loading levels. The correlations between surface modification,
morphology, dispersion/exfoliation and interfacial interaction of sheets and
the corresponding mechanical and thermal properties of the composites were
systematically investig...

Synthesis and characterization of a liquid crystalline epoxy containing azomethine mesogen for modification of epoxy resin
A novel liquid crystalline epoxy monomer, 1,1'-bis [4-(2,3-epoxypropoxyphenyleneininomethyl)1-2,2'dimethylbiphenylene (BMPE) was synthesized and characterized by infrared (IR) and Nuclear magnetic resonance (NMR) spectroscopy. The effect of BMPE content on mechanical and thermal properties of its blends with Diglycidyl Ether of Biphenol A (DGEBA) was investigated. BMPE presented a Schlieren textur...

Enhanced interfacial interaction of epoxy nanocomposites with activated graphene nanosheets
关键字：graphene composites
The interfacial properties of epoxy nanocomposites reinforced by thermally exfoliated graphene nanosheets (TEG) and activated thermally exfoliated graphene nanosheets (a-TEG) were compared. The specific surface area (SSA) of a-TEG with well-defined micro-mesopore size distribution was 1000 m2/g, which was much higher that of TEG (550 m2/g). The interfacial interaction between a-TEG and e...
