“…Two sharp peaks appeared in the Raman spectrum: D peak at 1.295 and G peak at 1,580 cm −1 . D peak originates from the vibration of the carbon atom presented in the sp 3 orbital, indicating the structural defects in the carbon plane and the disordered structural of the region; G peak corresponds to the first-order scattering of the E 2g phonon in-plane vibration of the carbon atom presented in the sp 2 orbital [24,25]. The I D /I G ratio of original GO is 1.10, while that of deposited GO is 0.92.…”

This article discusses about the significance of graphene oxide (GO) deposition on the surface of a titanium plate by electrophoretic deposition (EPD) method to improve the adhesive strength of Ti/polyetheretherketone (PEEK) interfacial adhesive. Firstly, the anodic EPD method was applied to a water dispersion solution of GO, and then the morphology and the properties of titanium plate surface were characterized by scanning electron microscopy and contact angle measurements before and after GO deposition. Furthermore, the changes in the properties of GO after heating at 390°C were characterized by Raman and Fourier transform infrared spectroscopies. According to the results of single lap tensile shear test, the adhesion strength of Ti/PEEK interface after the anodization and deposition of GO was 34.94 MPa, an increase of 29.2% compared with 27.04 MPa of sample with only anodization. Also, the adhesion strengths were 58.1 and 76.5% higher compared with the samples of only GO deposited (22.1 MPa) and pure titanium (19.8 MPa), respectively. POLYM.

“…2,3 Improvement in the ability to easily and rapidly tailor properties of such materials would have significant impact on many engineering applications, such as transportation, structures, etc. 4 It has been widely appreciated that it is crucial in matrix-filler nanocomposites for the interfacial bonding to be strong enough to effectively transfer stress from the matrix to the filler.…”

The design of graphene/polymer nanocomposites with improved mechanical properties requires characterization of the interfacial interactions between different types of graphene sheets and different polymers. Here, we explore the interactions in a graphene oxide (GO)/polymer nanocomposite and test the effect of thermal reduction of GO on adhesion. We demonstrate a versatile peeling test and applied it on a wide range of nanosheet fillers and polymers, which has great potential for expedited development of enhanced nanocomposites.We tested the interactions of GO and rGO nanofillers with widely used polymers, including poly(methyl methacrylate), polystyrene, acrylic, polyvinyl alcohol, polyetherimide, and polyimide. Our results show the effect of thermal reduction of GO on the interactions in polymer nanocomposites and rank the interfacial preferences of GO and rGO for different polymers.

“…As shown in Fig. b, the presence of graphene resulted in a slight decrease in the TSM and WA of the films, probably due to the impermeability and hydrophobic nature of carbon‐based nanofillers . In addition, the WA value of the SPI/G/PDCNTs film decreased by up to 41.2% with respect to the neat SPI film, suggesting the significant improvement in the water uptake properties of the SPI matrix.…”

The demands for strong integrated biopolymer materials have substantially increased across various industries. In this study, a biomimic strategy was proposed to prepare the poly(dopamine)‐functionalized carbon nanotubes (PDCNTs) via mussel‐inspired chemistry. The graphene dispersion was prepared in aqueous bovine serum albumin solution by ultrasonic treatment through a facile and green approach. Inspired by the excellent integration of mechanical properties and hierarchical nano/microscale structure of natural nacre, we fabricated soy isolate protein (SPI)‐based nanocomposite film with 2D graphene nanosheets and 1D surface‐functionalized PDCNTs through a layer‐by‐layer assembly process. The morphology and thickness of graphene nanosheets were analyzed by atomic force microscopy. The successful surface modification of PDCNTs was confirmed by X‐ray photoelectron spectroscopy and transmission electron microscopy. The cross‐linking hierarchical structure of the SPI hybrid film was observed in scanning electron microscopy images. A combination of multiple interfacial interactions and enhanced adhesion between the PDCNTs‐graphene conjugation and SPI matrix resulted in a remarkable improvement in the mechanical properties of the SPI‐based nanocomposites. When compared with the unmodified film, the tensile strength and elongation at break of the hybrid film were simultaneously increased by 158.93 and 78.67%, respectively. As a result of the enhanced tortuosity effect, the water vapor permeability was significantly reduced by 33.65%. In addition, the resultant film also possessed favorable water resistance, thermal stability, and ultraviolet–visible light barrier behavior. This work provided a novel bio‐inspired interfacial toughening strategy for constructing high performance biopolymer nanocomposites. POLYM.
