چکیده

This study focuses on the preparation and characterization of nanocomposite system with bio-based epoxy resin (Super SAP 100/1000, contains 37% carbon content) natural clays including Georgian clay Brazilian clay. was surface modified using an ultrasound processing in presence Decalin. to organophilic bentonite quaternary ammonium salts. The resulting nano particles were characterized XRD TEM confirm particle size reduction uniform distribution. as-fabricated nanocomposites flexure, DMA, TMA TGA. flexure analysis showed that composites have significant improvement strength (23–38%) modulus (28–37%). Delayed thermal degradation observed from TGA which major temperatures improved 7°-25°C. DMA improvements storage moduli (4–6%) coefficient expansion (CTE) (6–64%), respectively. notable mechanical properties suggested effective dispersion high degree polymer interaction. bio based content present Super Sap 100/1000 acts as plasticizer extensive ductility polymer.

Clay-Epoxy Nanocomposites: Processing and Properties

The work described in this paper is focused on evaluating the effect of the processing method and nanoclay (montmorillonite) content on the tensile, compressive, and impact properties of clay-epoxy nanocomposites. Nanocomposites are synthesized by two methods: mechanical mixing and shear mixing. Both these methods are capable of producing bulk quantities of clay-epoxy nanocomposites. X-ray diff...

Mechanical and Thermal Properties of Chemically Modified Epoxy Resin

Diglycidyl ether of bisphenol-A (DGEBA), having number average molecular weight (Mn) 375, was modified by incorporating the hydroxyl terminated polybutadiene (HTPB) based prepolymer using isophorone diisocyanate as a coupling agent. To increase the compatibility between the epoxy resin and HTPB part, polar groups were introduced in the later to achieve physical and chemical interactions between...

Thermal Stability of Imidazolium Modified Clay and Tgddm-based Epoxy Nanocomposites

High performance epoxy resin (tetra-glycidyl-4,4’diamino-diphenyl methane-TGDDM) is brittle and is sensitive to moisture absorption and thermooxidative effects. An approach to mitigate polymer sensitivity towards moisture and thermal effects is to add clay. The addition of clay to resin systems (e.g. diglycidyl ether bisphenol A-DGEBA) has often yielded an overall improvement in properties of t...
