Facile and green preparation of biobased graphene oxide/furan resin nanocomposites with enhanced thermal and mechanical properties

Abstract

Ƚ Electronic supplementary information availble. The photographs of cured samples of neat furan resin and its GO nanocomposites (Fig.S1).See A facile and green approach was developed to prepare biobased graphene oxide (GO)/furan resin nanocomposites by directly transferring GO from water dispersion into furan resin. The structure of nanocomposites was characterized by Fourier infrared spectroscopy (FTIR), X-ray diffraction (XRD) and scanning electron microscopy (SEM). A good dispersion of GO within furan resin was observed. Performance investigation revealed there was a significant improvement in thermal, mechanical and chemical resistance properties of biobased GO/furan resin nanocomposites when a low content of GO was introduced into neat furan resin. The nanocomposite with a low content of 0.05 wt % GO showed better improvement in tensile strength and Young's modulus of 72% and 282%, respectively. Thermal analysis of the nanocomposites also illustrated an enhancement in thermal stability. The obtained biobased GO/furan resin showed good chemical resistance.

High performance multiscale glass fibre epoxy composites integrated with cellulose nanocrystals for advanced structural applications

“…Albeit, the spectra of CNC/EP exhibit a similar diffraction pattern, but for a tiny broad shoulder hump at 22.5°observed for the 2.0 % CNC nanocomposite, corresponding to a sharp crystalline peak of CNC. This implies that CNCs were possibly well dispersed in epoxy and more importantly the parent crystal structure of cellulose I is well preserved in the nanocomposites [29]. In summary, the rheology, FTIR, mechanical properties, SEM and XRD studies provide evidence of interactions between CNCs and epoxy matrix.…”

Influence of a carbon-based tribofilm induced by the friction temperature on the tribological properties of impregnated graphite sliding against a cemented carbide

“…Furan has several characteristic adsorption peaks. The O-H stretching vibration is clearly observed at about 3,400 cm −1 , and the absorption bands at 1,625 cm −1 and 1,080 cm −1 are, respectively, due to the C=C and C-O-C stretching vibrations of furan resin [24,25]. In addition, there is an obvious XPS spectrum peak at 283.20 eV due to C-C/C=C.…”

Preparation and Characterization of Furan–Matrix Composites Blended with Modified Hollow Glass Microsphere

“…In addition, the loss factor tan δ in DMA is defined as the loss modulus/storage modulus ratio, indicating high sensitivity to the solid structural transformation of material. T g was calculated based on the tan δ loss factor peaks [11]. The temperature dependence of tan δ with respect to various composites is presented in Figure 8.…”

“…Furfural, which is the raw material of furan resin, can be readily obtained from the agricultural residues containing pentose [10]. Furan resin is extensively used within the foundry industry and as wood adhesives [11,12], which exhibits great performance at flame retardancy, unlike most organic materials [13,14]. Furthermore, furan resin contains a non-toxic furfuryl group; therefore, the emission of contaminants can be avoided during its synthesis and application [15].…”
