“…Polymer composites with GO have attracted great interest due to their unique properties, which are derived from extended interactions between the GO and the matrix and their wide potential applications such as electromagnetic wave shielding and sensors [24][25][26][27][28][29][30][31][32]. For example, Cao et al [33] found that the tensile strength and young's modulus of GO composites increased by 78 and 73%, respectively, when compared with pure polystyrene.…”

This work investigated the mechanical properties of epoxy resin composites embedded with graphene oxide (GO) using a novel two-phase extraction method. The graphene oxide from water phase was transferred into epoxy resin forming homogeneous suspension. Hyperbranched polyamine-ester (HBPE) anchored graphene oxide (GO HBPE ) was prepared by modifying GO with HBPE using a neutralization reaction. Fourier transform-infrared spectroscopy (FTIR), Raman spectroscopy, X-ray diffraction (XRD), and transmission electron microscopy (TEM) showed that the HBPE was successfully grafted to the GO surface. The mechanical properties and dynamic mechanical analysis (DMA) of the composites demonstrated that GO HBPE played a critical role in mechanical reinforcement owing to the layered structure of GO, wrinkled topology, surface roughness and surface area ascending from various oxygen groups of GO itself, and the inarching of HBPE and the reaction among GO, HBPE, and epoxy resin. The transferred GO HBPE /epoxy resin composites showed 69.1% higher impact strength, 129.1% more tensile strength, 45.3% larger modulus, and 70.8% higher strain compared to that of cured neat epoxy resin. The glass transition temperature (Tg) of GO HBPE /epoxy resin composites was increased from 135 to 141°C and their damping capacity was also improved from 0.71 to 0.91. This study provides guidelines for the fabrication of strengthened polymer composites using phase transfer approach.

“…Reaction between electrodes and electrolyte solution occurred depend on the surface area [22]. Carbon have smaller surface area, which only reached 16.30 m 2 /g, while surface area of the carbon paste electrodes with PANI modifications reached 29.26 m 2 /g [23]. Therefore, MCPE electrode was more effective than CPE on the electron transfer process, so that it can be used as electrode development.…”

An enzymatic biosensor has been developed for detection of hydrogen peroxide with immobilized Horseradish peroxidase (HRP). HRP was immobilized by using glutaraldehyde (GA) that cross linked with modified polyaniline (PANI) as mediator to improve electron transfer. Modified carbon paste electrodes (MCPE) PANI was more effective during electron transfer compared to carbon paste electrodes (CPE). Cyclic voltammetry method (VC) was used to determine the electrochemical properties of the modified electrode substrate to produce redox reactions. The effect of pH and temperature were analyzed by cyclic voltammetry. The optimum performance of HRP/GA/PANI was at pH 7 and 50°C. Kinetics parameters HRP enzyme were determined in optimum condition. The Michaelis-Menten constant (Km) value and current maximum (I max ) have been obtained as 1.71 mM and 0.29 mA.

“…The electroconductive property of polyaniline is caused by protonation in strong acid media when oxidative polymerization occurs [13]. The nano-size and fiber form of the polyaniline particle also influence its electroconductiveness because they contributed to a larger surface area of the electrodes [14]. Therefore, nanofiber-polyaniline MCPE were used to study the GOx bioanode with immobilization using crosslinking with glutaraldehyde.…”
