Influence of graphene oxide and graphene nanosheet on the properties of polyvinylidene fluoride nanocomposites

Abstract

In this study, graphene oxide (GO) and graphene nanosheets (GN) were prepared using natural graphite as a reinforcing agent, and different filler contents (1, 2, 3, and 4 wt%) were used to produce nanocomposites based on polyvinylidene fluoride (PVDF). In particular, a meltblending method was used as a 10 wt% masterbatch was prepared and then diluted to get the final samples via compression molding. A complete characterization in terms of X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), and scanning electron microscopy (SEM) confirmed that GO and GN were of high structural quality. Then, the nanocomposites were characterized in terms of thermal, rheological, electrical, and mechanical performances. The thermal stability of neat PVDF (4008C) was found to increase with both fillers addition reaching at 3 wt% 445 and 4638C for GO and GN, respectively. For the same concentration, the PVDF Young's modulus was found to increase by 32% for GN, while only a 7% gain was observed for GO. Similarly, the rheological and electrical resistivity results showed that GN was more effective than GO in improving the performances of these nanocomposites, with an optimum $3 wt% for the conditions tested.

Mechanical properties prediction of polypropylene/short coir fibers composites using a self‐consistent approach

“…Nowadays, thermoplastics can be found in a wide range of applications and fields due to their relatively low cost and easy processing, especially by injection molding. But most commodity polymers, such as polypropylene (PP), have relatively low mechanical properties limiting their use to non‐structural applications . Nevertheless, the addition of short natural fibers in these matrices was shown to substantially improve their mechanical performance without compromising their processability.…”

A Review on the Production Methods and Applications of Graphene-Based Materials

“…The selected solvent must be compatible with the polymer resin and be volatile to facilitate the evaporation or distillation processes [ 105 , 108 ]. A wide range of polymers including epoxy [ 109 ], polyvinyl alcohol (PVA) [ 110 ], polyvinyl fluoride (PVF) [ 111 , 112 ], polyethylene (PE) [ 113 , 114 ], polypropylene [ 115 , 116 ], polymethylmethacrylate (PMMA) [ 117 , 118 ], polyurethane (PU) [ 119 , 120 ], polystyrene (PS) [ 121 , 122 ] have been explored and found to be suitable for graphene/polymer composite manufacturing via the solution mixing technique. Consequently, polymer resin can intercalate between the graphite layers more easily during the composite fabrication process, thus, resulting in a uniform distribution of graphene or modified graphene materials in the polymer resin [ 123 ].…”

Compatibilization of PA6/ABS blend by SEBS-g-MA: morphological, mechanical, thermal, and rheological properties

“…In general, the crystallinity of the composite is related to the dispersed phase, which can act as nucleating agents in a polymer matrix. The polymer molecular chains can crystallize by themselves through a self-nucleation effect (homogeneous nucleation) or by introducing a nucleating agent (heterogeneous nucleation) [26,39]. Semicrystalline polyamide 6 may have its melting and crystallization behavior changed by the presence of a second component in polymer blends.…”
