“…Alkali, potassium permanganate, acetylation, silane treatment, benzoylation, acetone treatment, and acrylation are some of the commonly applied methods reported in literature. Such treatments aim to reduce or modify the available polar groups and to make them more hydrophobic to be compatible with polymeric matrix material to form the reliable composites (Aguiar et al, 2010;Bilba & Arsène, 2008;Candido et al, 2012;La Mantia and Morealle, 2011;Lopez et al, 2012;Mahesha et al, 2018;Motaung et al, 2015 Verma, 2012;Wirawan et al, 2011;Zhao et al, 2008). Table 2 shows tensile properties of raw and-treated bagasse fibers (Ramleea etal., 2019;Vilay et al, 2008).…”

Natural fiber composites expected to be in great demand in the coming years due to increased consumer awareness to reduce the waste and environmental pollution. Bagasse fibers available in plenty as an agro-residue and bio composites derived from such renewable resources offer potential for scale-up and value addition. This review provides an insight on current research trends on development and characterization of bagasse-based composites. Various chemical treatment methods and processing techniques used to improve the mechanical, thermal, acoustic, and aging properties of sugarcane bagasse reinforced composites are summarized in the review.

“…This may be due to the reduction of GO and the coupling between -O-H on the GO and -O-CH 3 in KH-560. according to the standard test methods (ASTM D 638-08 Type I [33] and ASTM D 790-03 [34]). For the tensile strength test, the composite samples were cut into a dumbbell-like shape and the dimension was determined according to type I.…”

“…The thermal stability of the samples was studied by thermogravimetric analysis (TGA) on a thermogravimetric apparatus (NETZSCH TG209, Selb, Germany) in an N 2 atmosphere at the heating rate of 10 • C·min −1 . The tensile and bending strength of the modified GE/EP, CB/EP, and Ag/EP composites were tested on a universal testing machine (SHIMADZU AGS-J, Kyoto, Japan) according to the standard test methods (ASTM D 638-08 Type I [33] and ASTM D 790-03 [34]).…”

et al. 2018

The dispersity of graphene (GE) in the matrix has an important influence on the thermal, mechanical, and electrical properties of its derived composites. In this paper, surface modification with a silane coupling agent and a double injection method were used to improve the dispersity of GE in epoxy resin (EP). The thermal, mechanical, and electrical properties of modified graphene/epoxy resin composites (modified GE/EP) were investigated by the thermogravimetric analysis, a four-probe method, and the tensile and bending strength. The results reveal that these properties of the composites can be improved significantly by using the modified GE as the filler. The surface of the modified GE/EP composite was smooth when the curing temperature was 75 °C. The weight loss of the modified GE/EP composite was lower than that of pure EP. The tensile and bending strength of modified GE/EP-0.07 (0.07 wt % modified GE) reached 74.65 and 106.21 MPa, respectively. In addition, the resistivity of modified GE/EP-0.1 (0.1 wt % modified GE) decreased to 52 Ω·cm, which was lower than that of CB/EP-1 (1 wt % carbon black, 95 Ω·cm) and Ag/EP-50 (50 wt % Ag particles, 102 Ω·cm). It is worth noting that the percolation threshold of the modified GE/EP composites was 0.025 vol % modified GE. These results show that the modified GE/EP composites have a potential application in conductive ink when the modified GE is used as the conductive filler.

“…[ 158,159 ] The bast fibers extracted from Grewia Serrulata trees could provide reinforcement to unsaturated polyester resin. [ 160 ] The tensile strength and tensile modulus of composites was higher than untreated samples by 53% and 8%, respectively, after acetylation treatment on fibers. The fractography of the samples indicated that the bonding between the fibers and the matrix was obviously improved after treatment.…”

Surface/interfacial engineering is an essential technique to explore the fiber materials properties and fulfil new functionalities. An extensive scope of current physical and chemical treating methods is reviewed here together with a variety of real‐world applications. Moreover, a new surface/interface engineering approach is also introduced: self‐assembly via π–π stacking, which has great potential for the surface modification of fiber materials due to its nondestructive working principle. A new fiber family member, metal‐oxide framework (MOF) fiber shows promising candidacy for fiber based wearable electronics. The understanding of surface/interfacial engineering techniques on fiber materials is advanced here and it is expected to guide the rational design of future fiber based wearable electronics.
