“…Some other articles [ 38 , 39 , 40 ] reported the usage of ethanol and the nanocomposites showed improved load transfer efficiency, as well as an improved glass transition temperature. Other solvents, like isopropanol [ 41 , 42 ], THF [ 43 , 44 ], butanone [ 45 , 46 ], acetone [ 47 , 48 ], and dichloromethane [ 49 ], have also been reported in the processing of epoxy/graphene nanocomposites. However, in all of these studies, the dosage of solvents had not been specified.…”

DMF is one the most commonly-used solvents for preparing graphene nanocomposites. Various processing variables for DMF are being used for the preparation of epoxy/graphene nanocomposites. Whilst the emphasis of all of these reported studies are on the improvements in mechanical, and other properties, of the epoxy/graphene nanocomposites, there is no study investigating how DMF affects the processing and how it is associated with the final properties of the nanocomposites. In this work, different dosages of DMF have been used to prepare nanocomposites. Mechanical testing, X-ray diffraction (XRD), dynamic mechanical analysis (DMA), thermogravimetric analysis (TGA), and scanning electron microscopy (SEM) have been used to analyze the effectiveness of DMF dosage on the properties of processed nanocomposites. Larger dosages of DMF are not always ideal for dispersing graphene as it promotes reaggregation of graphene during the processing.

“…In another recent study, an epoxy resin based on gallic acid and a formaldehyde resin were synthesized as matrix of a glass fiber composite material (Chen et al 2015). Additionally, Hou et al (2016) prepared bio-based epoxy resins from renewable gallic acid; the resulting bio-based nanocomposite and glass fiberreinforced composite was formulated with succinic anhydride as a curing agent.…”

An aromatic epoxy monomer, formed by glycidylation of gallic acid, was crosslinked by adopting different curing agents to obtain bio-based, crosslinked resins with suitable engineering properties. Specifically, triand tetra-glycidyl ether of gallic acid (GEGA) were obtained using a twostep synthesis. These bio-based monomers were cured in the following three epoxy formulations: a stiff cycloaliphatic primary amine, isophorone diamine, and a flexible polypropylene oxide amine (Jeffamine D-230). Next, the homopolymerization of GEGA was studied using an ionic initiator, N,N-dimethylbenzylamine, and a complex curing mechanism highlighted by calorimetric and mass spectra analysis. Calorimetric and rheological measurements were used to compare the curing behavior of the studied GEGA-based formulations. Mechanical properties of the gallic acid-based epoxy resins were comparable with those of standard epoxy resin formulations, based on di-glycidyl ether of bisphenol A. Thermogravimetric analysis of cured samples showed a relevant char content at high temperatures.

“…105 Coatings and composites are major downstream applications of epoxy resins, and different kinds of biobased epoxy resins were studied as resin matrix, such as 2,5-furandimethanol, 106 resorcinol, 107 and gallic acid. [108][109][110] Among them, the carbon nanotubes or graphene reinforced gallic acid-based epoxy resin was proved to possess better mechanical properties, excellent thermal conductivity and electrical conductivity. 109,110…”

Due to the rapid depletion of crude oil and serious environmental pollution, the synthesis of polymers from renewable resource is becoming more and more important. Up to now, a great variety of biomass and bio-based platform compounds have been taken to prepare the polymers. However, as two representative thermosetting resins, epoxy and benzoxazine resin derived from renewable feedstocks only obtain limited attention compared with the popular bio-based plastics, including PLA, PBAT and PHBV etc. The reason might be that the properties of previously reported thermosetting resins directly obtained from biomass are usually unsatisfied, and their application fields are limited. In this paper, the latest development on the synthesis of highperformance bio-based epoxy and polybenzoxazine resins are reviewed. In addition, to further broaden their applications, the functionalization strategies are also summarized. The objective of this work is to help us fully aware the present situation of bio-based thermosetting resins and then promote their faster development, especially practical application.
