“…for epoxy nanocomposites reinforced with graphene nanoplatelets (up to 3 wt % filler). In the rubbery region (150°C onwards), the effect of the rigid filler is more pronounced, and storage modulus increases with increasing GrNP content due to a more pronounced effect in the restriction of chain mobility at high temperatures . Also, functionalization increased stiffness in the rubbery region, which could be an indicative of better adhesion when functional groups compatible with epoxy resins are present in the surface of GrNPs.…”

Thermoset resins are widely used for composite applications due to their excellent mechanical properties. To further enhance their performance, nanofillers such as graphite nanoplatelets (GrNP) have been used, and extra improvement may arrive from surface treating these fillers. This study aims to evaluate the influence of GrNP content and treatment with (3‐glycidyloxypropyl)trimethoxysilane and (3‐aminopropyl)triethoxysilane on curing behavior and mechanical and dynamic mechanical properties of GrNP/epoxy composites. Composites reinforced with 0.25 wt % GrNP displayed increased tensile strength by 11.8% compared to the neat resin. Addition of 0.5 wt % GrNP increased the glass transition temperature in 10°C compared to the neat polymer. Silane treated fillers showed an improvement in tensile strength and dynamic‐mechanical properties compared to the neat resin and non‐treated GrNP/epoxy composites at similar filler content. © 2018 Wiley Periodicals, Inc.

Lignocellulosic fibers have been one of the most used reinforcements for different types of composites. In this context, grape stalks—often discarded in landfills—can be a potential reinforcement for composites. The present study aimed to incorporate in natura and alkali treated grape stalks into the polystyrene (PS) matrix. Initially, the grape stalks were treated with NaOH and 10, 20, and 30 wt % of stalks were added into the PS matrix. The alkaline treatment of the grape stalk fibers promoted the removal of hemicellulose and the partial removal of lignin, thus increasing the surface roughness and crystallinity index of the fibers. An improvement in the mechanical and dynamic‐mechanical properties and an increase in the maximum degradation temperature of the composites were observed. In conclusion, the use of grape stalks is a promising alternative for reinforcing composites, and, in addition, a more proper destination can be given to this type of residue. © 2019 Wiley Periodicals, Inc.

“…Green polymeric composites composed of polymers reinforced with cellulose derivative not only address environmental issues but also improve the mechanical and electrical properties and the biodegradability of the polymeric materials, owing to the biodegradability, high mechanical properties, low density, and availability of cellulose. They are also much less abrasive than inorganic mineral counterparts to processing machinery, are less dangerous for production employees in case of inhalation, result in promising thermal and acoustic properties, are easily incinerated, and are capable of producing composites with lower specific weight . The biodegradable properties of green polymeric composites imply the degradation of a polymer in natural environment that includes changes to the chemical structure, the loss of mechanical and structural properties, and conversion into other compounds that are beneficial to the environment .…”

Owing to their abundance, high strength and stiffness, and low weight and biodegradability, nanocellulose (NC) is regarded as a promising candidate for the preparation of green composites. The high reinforcing effect assigned to the mechanical percolation phenomenon of NC is due to the stiff continuous networks of cellulosic nanoparticles linked via hydrogen bonding. Compared to nanocrystalline cellulose, NC fibers result in more significant improvement to the modulus, stiffness, and strength as aspect ratio NC fiber is higher compared to NC crystal. Indeed, in the case of biopolymer composites, the reinforcement effect of NC is attributed to the NC‐polymer interactions and the reinforcing effect occurring through effective stress transfer at the NC‐polymer interface. The NC‐reinforced composites tend to become more brittle as the concentration of the reinforcing particles increase up to the saturated level, due to the reduction in surface adhesion between filler and matrix. Due to its promising mechanical and structural stability, NC composites have been used widely in many industrial applications such as food packaging, electronic applications, and tissue engineering.
