“…If the dispersion is good, it is easy to form a continual conductive network with the same filler content. 2 In addition, as shown in Figure 9, EMI shielding effectiveness (SE) tended to increase with increasing frequency in all samples. This means that the higher frequency has the shorter wavelength of the electromagnetic wave and it becomes closer to the fiber size in the resin.…”

“…1–6 According to the rule of mixture, physical properties were increased by increasing the fiber content with a matrix such as polyamide (PA), polypropylene (PP), polycarbonate (PC) and polyethylene (PE) which are mainly used in automotive industry. 1–4 For higher efficiency of reinforcing, the surface treatment onto the fiber surface was applied by grafting graphene oxide onto fiber surface in PA6/CF composite. 5 Furthermore, the sizing materials such as epoxy, phenoxy and polyimide and the level of sizing materials on fiber surface were compared in PC/CF composite.…”

In the present study, the difference of long carbon fiber reinforced thermoplastic (C-LFT) depending on the type of polymer resins at the same carbon fiber content (30 wt.%) was compared. The different types of C-LFT were made using five polymer resins such as polyamide 6, polyamide 6,6, polycarbonate, high density polyethylene and polypropylene. Tensile test, flexural test, and unnotched Izod impact test were carried out and the cause of difference in the mechanical properties was considered by analyzing the adhesion characteristics. Fracture appearance and work of adhesion between the fiber and the resin were observed. In addition, the difference and its cause in electromagnetic interference shielding effectiveness (EMI SE) was investigated. From the results, the polyamide 6 is most appropriate to the carbon fiber among the samples in the aspects of interfacial shear strength and fiber dispersion.

“…Carbon fiber is one of the most useful materials used in automotive, sports and aerospace applications due to its high corrosion resistance, mechanical properties, and excellent coefficient of thermal expansion [ 11 , 12 ]. The incorporation of carbon fiber up to 20 wt.% in polypropylene (PP)/high-density polyethylene (HDPE) composites showed 60%, 18%, and 23% enhancement in impact, tensile and flexural properties of matrices, respectively [ 13 ]. Agglomeration is a major factor that reduces the compatibility of carbon fiber with resins at higher fiber substitution, resulting in reduced overall mechanical properties of the composites [ 12 ].…”

This research focused on enhancement of mechanical properties in carbon fiber (CF)-filler-reinforced linear low-density polyethylene (PE) matrix composites. A hand layup method using an oven was used as the fabrication method. Improvement in adhesion was achieved by oxygen plasma treatment to the PE matrix. CF and PE were initially mixed by normal stirring, ultrasonication and mechanical stirring before being filtered and dried for fabrication. Better tensile results were observed with a plasma-treated polyethylene (PEP)/10 wt.% CF combination, with a maximum tensile strength of 21.5 MPa and improvement in the properties of up to 12.57% compared to non-plasma PE with the same CF addition. The addition of carbon fibers at 13 and 15 wt.% resulted in a reduction in the tensile strength properties to 18.2 MPa and 17.7 MPa, respectively. This reduction in tensile strength was due to agglomeration of CF with plasma- and non-plasma-treated PE. The fabrication condition of 180 °C temperature for 20 min showed better tensile properties than other conditions. The SEM results following tensile testing revealed enhanced CF filler adherence with plasma PE results, as well as fewer surface deformations. A higher flexural strength of 25.87 MPa was observed for the plasma treated PE/7 wt.% CF combination.

“…When the employed reinforcing agent is nanosized, its high aspect ratio promotes a very fine dispersion in the binary system, along with a high surface area of interaction with the two polymers. Therefore, nanofillers [ 10 ] are replacing conventional fillers [ 11 ] in the reinforcement of PE/PP binary systems. However, these novel co-factors are expensive; thus, the mass production of biphasic polyolefin systems reinforced with targeted fillers is very limited [ 12 ].…”

Non-Isothermal Crystallization Behavior and Thermal Properties of Polyethylene Tuned by Polypropylene and Reinforced with Reduced Graphene Oxide

et al. 2020

This research work is the first to report thermal stability, heat deformation resistance, and crystallization behavior of a Polyethylene (PE)-based biphasic polyolefin system reinforced with Reduced Graphene Oxide (RGO), which was obtained through Graphene Oxide (GO) chemical reduction. Polypropylene (PP) represented the polymeric dispersed phase. A strategic PE/PP/RGO manufacturing procedure was employed to thermodynamically localize RGO at the PE/PP interface, as confirmed by Transmission Electron Microscopy (TEM), bringing a uniform micro phase dispersion into the macro phase. In addition, studies of PE non-isothermal crystallization kinetics indicated that the morphology tunable micro phase and the nanolayered RGO promoted a nucleation-controlled PE crystallization, which was supported by Polarized Light Optical Microscopy (PLOM). This, together with fine morphology, justified the remarkable enhancement registered for the ternary system’s thermal stability and heat deformation resistance. Different filler loads were employed, with weight fractions of 2% and 4%. It was observed that the former, being better exfoliated and more homogeneously distributed at the PE/PP interface than the latter, led to a more improved PE crystallization, alongside a greater ternary system’s thermal properties. Moreover, the thermal stability of PE/PP reinforced with 2% of RGO was even higher than that of virgin PP, while their heat deformation resistance values were found to be similar. Therefore, this unique outcome provides industries, such as the energy and automotive sectors, with the opportunity to substitute PP-rich products with those mostly comprised of a cheaper, more abundant, yet performant PE.
