Epoxy composites with functionalized molybdenum disulfide nanoplatelet additives

Abstract

As a typical layered inorganic analogue of graphene, molybdenum disulfide (MoS2) has gained intensive attention and become a research hotspot due to its unique two dimensional nanostructure and excellent properties.

Polyaniline nanorod adsorbed on reduced graphene oxide nanosheet for enhanced dielectric, viscoelastic and thermal properties of epoxy nanocomposites

“…Figure 9(A) shows the morphology of the tensile fractured surface of pure epoxy that exhibits a relatively smooth fractured surface with some river like impression indicating its brittle nature. [ 51 ] However, with the incorporation of P@G, the surface becomes rougher which is evident from the SEM images of E/P@G3 (Figure 9(B)) and E/P@G9 (Figure 9(C)). E/P@G3 shows that P@G is uniformly dispersed in the epoxy matrix which might have resulted in improved interfacial interactions between the filler and epoxy matrix.…”

Thermomechanical Properties of Carbon Fabric Reinforced Epoxy Laminates with h-BN and MoS2 Fillers

“…This was attributed to the restriction for epoxy chain mobility due to the presence of MoS 2 . Zhao et al 28 reported an increment in the Tg by 11°C and decrement in the E′ by 105 MPa for 0.7% silane functionalized MoS 2 reinforced epoxy resin composite.…”

“…In this regard, several researchers paid attention to improve the thermal stability, storage modulus (E′), Tg, and toughness of the epoxy matrix by incorporating the fillers. The commonly used fillers are alumina (Al 2 O 3 ) 17 , boron carbide (B 4 C) 18 , silicon dioxide (SiO 2 ) 19 , nanoclay 20,21 , graphene [22][23][24] , boron nitride (BN) 25,26 , molybdenum disulfide (MoS 2 ) 27,28 . The thermomechanical properties improvement depends on the type, size, shape, and quality of the filler dispersion.…”

Improving Fracture Toughness of Tetrafunctional Epoxy with Functionalized 2D Molybdenum Disulfide Nanosheets

“…A few studies have reported using functionalized MoS 2 for thermosetting polymers such as epoxy [41]. Chhetri et al used the hydrothermal method for synthesizing CTAB functionalized MoS 2 platelets leading to the formation of microparticles by self-assembly of nanosheets.…”

“…However, this study did not evaluate the bulk properties of the epoxy nanocomposites. Zhao et al focused on improving the tensile properties of low-temperature bifunctional epoxy using 3-mercaptopropyltriethoxysilane functionalized MoS 2 nanosheets [41]. The three-step method of intercalation, exfoliation followed by chemical modification using silane functional molecules was employed.…”
