“…The polymer matrix composites (PMCs) are commonly used in construction, automotive, and aerospace mainly because of high strength to weight ratio [1][2][3]. In PMCs, thermosetting epoxy is the most commonly used matrix [4][5][6][7].…”

Abstract:The topographical features of fractured tensile, flexural, K1C, and impact specimens of 1.0 wt% Multi-Layer Graphene (MLG)/nanoclay-epoxy (EP) nanocomposites have been investigated. The topographical features studied include maximum roughness height (Rmax or Rz), root mean square value (Rq), roughness average (Ra), and waviness (Wa). Due to deflection and bifurcation of the cracks by nanofillers, specific fracture patterns are observed. Although these fracture patterns seem aesthetically appealing, however, if delved deeper, they can further be used to estimate the influence of nanofiller on the mechanical properties. By a meticulous examination of topographical features of fractured patterns, various important aspects related to fillers can be approximated such as dispersion state, interfacial interactions, presence of agglomerates, and overall influence of the incorporation of filler on the mechanical properties of nanocomposites. In addition, treating the nanocomposites with surfaces of specific topography can help improve the mechanical properties of nanocomposites.

“…Namun begitu, daya Van Der Waals yang kuat antara kepingan grafin membuatkan GNps cenderung untuk bergumpal pada polimer matriks dan seterusnya mengakibatkan tumpuan tegasan (Guo et al 2013). Penggumpalan tersebut boleh dielakkan dengan menggunakan pelarut organik dan memilih kaedah penyebaran yang sesuai (Atif & Inam 2016).…”

“…However, this is not sufficient for applications requiring high energy capacity. Single layer graphene has a high theoretical lithium storage capacity of 744 mAh·g −1 , but graphene has a tendency to stack due to van der Waals interactions between graphene layers [24]. The incorporation of TMO NPs inhibits the aggregation of graphene layers [25].…”

Single layer graphite, known as graphene, is an important material because of its unique two-dimensional structure, high conductivity, excellent electron mobility and high surface area. To explore the more prospective properties of graphene, graphene hybrids have been synthesised, where graphene has been integrated with other important nanoparticles (NPs). These graphene–NP hybrid structures are particularly interesting because after hybridisation they not only display the individual properties of graphene and the NPs, but also they exhibit further synergistic properties. Reduced graphene oxide (rGO), a graphene-like material, can be easily prepared by reduction of graphene oxide (GO) and therefore offers the possibility to fabricate a large variety of graphene–transition metal oxide (TMO) NP hybrids. These hybrid materials are promising alternatives to reduce the drawbacks of using only TMO NPs in various applications, such as anode materials in lithium ion batteries (LIBs), sensors, photocatalysts, removal of organic pollutants, etc. Recent studies have shown that a single graphene sheet (GS) has extraordinary electronic transport properties. One possible route to connecting those properties for application in electronics would be to prepare graphene-wrapped TMO NPs. In this critical review, we discuss the development of graphene–TMO hybrids with the detailed account of their synthesis. In addition, attention is given to the wide range of applications. This review covers the details of graphene–TMO hybrid materials and ends with a summary where an outlook on future perspectives to improve the properties of the hybrid materials in view of applications are outlined.
