“…The surface contact angle diminishes from 42° to 10° as a result of increasing graphene. This decreasing trend conforms well to that related to graphene oxide content as proposed by Yang et al and Da et al [ 43 , 44 ]. Namely, when composed of more graphene, the nanofiber films have greater wettability.…”

“…The electromagnetic waves are attenuated by reflection, absorption, and multiple absorption, and multiple reflection. The physical characteristics, organizational structure, and shape of the shielding materials are associated with the electromagnetic shielding effectiveness [ 44 , 47 , 48 ]. Aluminum foils use the reflection mechanism to debilitate the energy of electromagnetic waves, and the adhered PVA/GR nanofiber films have a porous structure, which is able to debilitate the incident waves via the multi-reflection [ 49 ].…”

With the aim of achieving controllable mass production of electrospun nanofiber films, this study proposes and investigates the feasibility of using a custom-made linear electrode- electrospun device to produce conductive graphene (GR)-filled polyvinyl alcohol (PVA) nanofibers. The film morphology and diameter of nanofibers are observed and measured to examine the effects of viscosity and conductivity of the PVA/GR mixtures. Likewise, the influence of the content of graphene on the hydrophilicity, electrical conductivity, electromagnetic interference shielding effectiveness (EMSE), and thermal stability of the PVA/GR nanofiber films is investigated. The test results show that the PVA/GR mixture has greater viscosity and electric conductivity than pure PVA solution and can be electrospun into PVA/GR nanofiber films that have good morphology and diameter distribution. The diameter of the nanofibers is 100 nm and the yield is 2.24 g/h, suggesting that the process qualifies for use in large-scale production. Increasing the content of graphene yields finer nanofibers, a smaller surface contact angle, and higher hydrophilicity of the nanofiber films. The presence of graphene is proven to improve the thermal stability and strengthens the EMSE by 20 dB at 150–1500 MHz. Mass production is proven to be feasible by the test results showing that PVA/GR nanofiber films can be used in the medical hygiene field.

“…The introduction of these nanofillers did not reduce the transmittance considerably, and thus, the coatings produced can be considered highly transparent. These results are similar to the results found in the literature for GO [20][21][22] and imply that the VTES functionalization did not negatively affect the transmittance of the coating. On the other hand, although the coatings containing rGO and rGOvtes presented a lower relative transmittance (approx.…”

“…They determined that the bilayer compound exhibited higher hardness, indentation elastic modulus, and resistance to scratch than the pristine PMMA films. If in addition to having improved mechanical properties, the final coating is also transparent, then it is suitable for its use in optical devices, for instance as a touchscreen protective coating in the smartphone industry [20][21][22].…”

Custom-Made Chemically Modified Graphene Oxide to Improve the Anti-Scratch Resistance of Urethane-Acrylate Transparent Coatings

et al. 2019

In this work, a thermoset ultraviolet (UV)-cured polyurethane-acrylate resin was doped with different chemically-modified graphene obtained from a commercial graphene oxide (GO): as-received GO, chemically reduced GO (rGO), GO functionalized with vinyltriethoxysilane (VTES) (GOvtes), and GO functionalized with VTES and subsequently reduced with a chemical agent (rGOvtes). Modified graphene was introduced in the oligomer component via solvent-assisted process using acetone, which was recovered after completion of the process. Results indicate that the GO-doped oligomers produce cured coatings with improved anti-scratch resistance (above the resistance of conventional coatings), without surface defects and high transparency. The anti-scratch resistance was measured with atomic force microscopy (AFM). Additionally, results are presented in terms of Wolf–Wilburn scale, a straightforward method widely accepted and employed in the coating industry.

“…Twodimensional graphene oxide (GO), is an amphiphilic material which contains hydroxyl and carboxyl groups on the edges and epoxy and hydroxyl groups on the basal plane 9,10 and has been used with CNTs in the fabrication of transparent conducting lms. 11 Due to its amphiphilic nature, GO can easily disperse agglomerated CNTs onto their surface and form a stable aqueous suspension. 12 At the same time, GO sheets provide extra transport paths to some areas where the CNTs are disconnected.…”
