“…To further confirm the modification of MoS2 by CTAB, XRD was performed for CTAB-MoS2 and pristine MoS2, and the corresponding reflection plane are shown in Figure 2b. For pristine MoS2, an intense reflection peak at 2θ = 14.48° (corresponding to the interlayer distance of 0.62 nm) was observed, which was ascribed to the (002) reflection plane [18]. In contrast, the (002) peak of CTAB-MoS2 shifted to a lower 2θ (~7.5°).…”

“…The CTAB-embedded MoS 2 nanosheets were prepared by a facile hydrothermal route as reported in our earlier work [18]. Typically,~1.2 g of Na 2 MoO 4 ·2H 2 O and 3.2 g of CH 4 N 2 S were dissolved in 60 mL of distilled water.…”

“…The 2-D layered MoS 2 possesses high modulus of~300 GPa and has proven to be a very efficient filler in reinforcing polymer matrices [10,11]. In recent times, MoS 2 has been used as a reinforcement filler in polymer matrices such as polyethylene, poly(vinylalcohol), epoxy, polystyrene, methyl methacrylate, chitosan, polyurethane, nylon, polyamide, methylcellulose, and so forth, and significant enhancements in mechanical, thermal, tribological, and fire resistance properties have been recorded with small weight fractions of MoS 2 [9,[11][12][13][14][15][16][17][18][19][20]. Among the 2-D reinforcing filler, graphene has been widely used and has found wide acceptance in the scientific and industrial realms [21].…”

“…Hence, the preparation of mono-or multilayer MoS 2 and its functionalization is crucial to realize the full reinforcing potential. Many prior reports used functionalized MoS 2 nanosheets to reinforce the polymer matrix, and it has been observed that suitably tuned MoS 2 nanosheets could endow significant enhancement in mechanical, thermal, and other properties [11][12][13][14][15][16][17][18]. Feng et al used dodecanethiol as an antioxidant and surface modifier to produce defect-free MoS 2 by direct ultrasonication of bulk MoS 2 and prepared the polyethylene nanocomposites by incorporating defect-free modified MoS 2 [9].…”

Molybdenum disulfide (MoS 2 ) was functionalized by cetyltrimethylammonium bromide (CTAB) through a one-pot hydrothermal technique, and subsequently, linear low-density polyethylene (LLDPE) composites were prepared. The attachment of alkyl chains of CTAB onto the MoS 2 surface was confirmed by Fourier transform infrared spectroscopy (FTIR). The enhanced mechanical properties of the composites relative to neat LLDPE revealed good compatibility between MoS 2 and LLDPE. The improvement in thermomechanical properties further substantiated good interaction between MoS 2 and LLDPE. The thermal stability of the prepared composites showed a small decrease in onset degradation temperature. Nevertheless, the char residue formation was found to be promoted in the presence of MoS 2 .

“…The fundamental properties of the material gets altered by adding nanofillers, namely, silica, alumina, titania etc, to acquire the required electrical, thermal, and mechanical properties . One dimensional nanofillers such as carbon nanotubes and 2D nanofillers like graphene reinforces well with polymer matrices and they are conductive, which limits its usage as insulant in large power apparatus such as electric motors, cables, capacitors and to use as an electric field grading material .…”

The surface discharge inception voltage (SDIV) of epoxy MoS2 nanocomposite is high under DC voltage compared to AC voltages. It is also observed that SDIV increases up to 0.5 wt% of MoS2 added epoxy resin and above which a marginal reduction in SDIV is observed. Surface charge accumulation is less with epoxy nanocomposite compared with epoxy resin. With increase in percentage of MoS2, complete reduction in charge retention time is observed. Surface roughness measurement with the surface discharge caused damage zone with epoxy nanocomposites indicate that surface roughness is less when the percentage of MoS2 is increased and above certain weight percentage, the surface roughness is almost same. Epoxy nanocomposites show a marginal increase in contact angle with increase in weight percentage of molybdenum disulfide. LIBS studies indicate that the crater depth and the plasma temperarure measured is low for epoxy nanocomposites with 0.5 wt% MoS2. POLYM.

In this paper, a series of graphitic carbon nitride (g-C 3 N 4 ) was synthesized under different thermal oxidation etching temperatures and epoxy/g-C 3 N 4 composites were prepared via solution blending. The morphology and structure of g-C 3 N 4 were investigated by transmission electron microscope, X-ray diffraction (XRD), Fourier transform infrared spectroscopy, and X-ray photoelectron spectroscopy. The tensile fracture morphology and structure of epoxy resin (EP) composites were demonstrated by scanning electron microscopy and XRD, respectively. Mechanical properties of EP composites were characterized by tensile testing, and the thermal performances were investigated by dynamic mechanical thermal analysis and thermal gravimetric analysis. The results revealed that the active groups on g-C 3 N 4 sheets increased under thermal oxidation etching and the C to N ratio of g-C 3 N 4 decreased from 0.94 to 0.76 with the increasing etching temperature. Noticeably, the tensile strength of EP composites was enhanced by 58% with the addition of C 3 N 4 -NS-500 and the thermal properties were also improved significantly, including T 0.5 (the decomposition temperature at the mass loss of 50%) increased by 21.5 C and glass transition temperature improved by 8 C. © 2020 Wiley Periodicals, Inc.
