“…. XRD studies revealed that the 1 wt% nanoclays show better exfoliation within the matrix, and the cured DGEBA/ECO/C30B (8:2:0.1) system does not exhibit any diffraction peak in their spectra . It concluded that the nanocomposites synthesized using mechanical mixing followed by ultrasonication indicate that the nanoclays exfoliated within the DGEBA/ECO system.…”

The present study highlights the structure and property relationships of epoxidized castor oil (ECO) toughened Diglycidyl Ether of Bisphenol A (DGEBA) epoxy nanocomposites. Toughened epoxy systems have been prepared by an addition of 10-40 wt% ECO to the DGEBA epoxy resin. Nanocomposites were prepared by mixing small amounts of Cloisite 30B (C30B) clay and 3-aminopropyltriethoxysilane to the DGEBA/ECO blends. The chemical structure of toughened systems was confirmed using proton nuclear magnetic resonance and fourier transform infrared spectroscopy. The triethylenetetraamine-cured DGEBA/ECO/C30B (8:2:0.1) nanocomposites exhibited tensile strength (50 MPa), tensile modulus (1.7 GPa), flexural strength (120 MPa), flexural modulus (3.02 GPa), and elongation (19%). The fracture toughness (critical intensity factor, K IC ) and fracture energy (critical energy release rate, G IC ) of DGEBA/ECO/C30B (8:2:0.1) system found to be higher than the other systems (2.5 MPa.m 1/2 and 1.8 kJ/m 2 for K IC and G IC , respectively). The thermal stability and heat of reaction of DGEBA/ECO blends increase with the addition of C30B clays that were analyzed using thermogravimetric analysis and differential scanning calorimetry. Rheological characterizations of uncured samples revealed a pronounced effect of the C30B clay on the DGEBA/ECO blend systems that exhibited a shear-thickening behavior. On the other hand, the dynamic mechanical properties also revealed that the addition of C30B clays to the DGEBA/ECO blend a significant enhancements in viscoelastic and cross linking density behavior. Scanning electron microscope analysis was used to study the fractured morphology of DGEBA, DGEBA/ECO, and its nanocomposite systems.

“…Regarding the tensile properties, a 74.6 times higher Young's modulus was reported for the 60:40 (modified oil-DCDP) composite containing 40 wt.% of glass fibers. Ray et al investigated the behavior of a blend of an epoxy resin and maleated castor oil co-reacted with an amine and filled with 10 wt% of fly ash [112].…”

Polymeric materials from renewable resources have attracted a lot of attention in recent years. The development and utilization of vegetable oils for polymeric materials are currently in the spotlight of the polymer and chemical industry, as they are the largest renewable platform due to their universal wide availability, ingrained biodegradability, low cost, and excellent environmental aspects (i.e., low ecotoxicity and low toxicity toward humans). These excellent natural characteristics are now being taken advantage of in research and development, with vegetable oil derived polymers/polymeric materials/composites being used in numerous applications including paints and coatings, adhesives, and nanocomposites. The aim of this review paper is to give a fundamental description of the various vegetable oil applications in polymer materials and its recent developments. Particular emphasis will be placed on study and main application of triglyceride based additive for polymer and to give the reader an insight into the main developments is discussed.

This study deals with the synthesis of vegetable oil (VO)-derived formulated resins with high bio-based content (30–77%) as potential renewable alternatives to conventional fossil-based vinyl ester (VE) and unsaturated polyester (UP) resins. First, epoxy acrylate was synthesized from a commercial epoxy resin via acrylation with acrylic acid. Then, acrylated epoxidized sesame oil (AESSO) and maleated castor oil (MCO) were synthesized and spectrally characterized. Afterward, networks of VE, AESSO, and MCO or their binary blends were prepared. The curing trend of the resins was investigated by differential scanning calorimetry. According to thermal and thermomechanical analysis, all of the VO-based networks possessed slightly inferior properties compared to those of VE. However, the adhesion strength of the VO-based alloying systems was higher than that of their petroleum-based counterpart based on T-peel and lap shear tests. Overall, it was concluded that the bio-resourced alloys could be considered as good alternatives to VE and UP resins, and the novel bio-resin formulations may be designed for adhesives, the polymer–matrix composites, and surface coating applications.
