“…Recent studies revealed that addition of glass fibre up to 30 wt.% exhibits better mechanical strength, hence 30% of glass fibre was kept constant to developed novel composite. Graphene oxide was synthesis by modified hummer's method [25]. Abutilon indicium leaf extract was used to reduce the graphene oxide to avoid the usage of harmful chemicals such as hydrazine hydride, which cause several health issues.…”

“…The peak arises near 2854 cm −1 is related to C-H stretching vibration. These hydroxyl groups might absorb water molecules and phenolic functional group from the carboxylic group of green extract [25]. C=O stretching vibration of carboxyl groups was detected at 1672 cm −1 .The presence of carboxylic group help in increasing the interaction between the polymer materials that helps in better adhesion.…”

Bio-reduction of composite materials is the modern approach to facilitate the researchers to avoid toxic chemical exposure during reduction process. In this study, the green reduction of graphene oxide using Abutilon indicum (Tamil name: Thuthi) plant leaves extracted from various solvents were used as green filler material (0.3, 0.6 and 1 wt.%) in glass fibre epoxy composite. Compression moulding process was adopted to fabricate bio-reduced graphene oxide (BGO) filler incorporated polymer matrix composite. Tensile, flexural, toughness, impact test and fracture surface morphology analysis have been conducted over developed composite. Flame retardancy behaviour was studied based on UL94 standard. Outcome of the study revealed that Abutilon indicum act as the better reducing agent to reduce graphene oxide. XRD, FTIR results depicts the proper distortion of graphite flask. Addition of BGO in polymer matrix improvises the tensile, flexural and impact strength of matrix material up to 28%, 55% and 80%. Herein addition of 0.6 wt.% of BGO showcase better fracture toughness and flexural strength, further increment in BGO show negative effect in strength. Occurrence of delamination failure was notified in fracture surface morphology.

“…Magnesium (Mg) and its alloys holds various outstanding properties, such as low density, high thermal conductivity, high damping resistance and better shielding characteristics [1], these properties make Mg as a prime material in various fields of application such as automobile, workstation parts, aerospace components and mobile phones [2][3]. However, Mg and its alloys are highly chemical reactive and likely to agonize severe corrosion in almost all industrial environments during service, that extremely limits their possible application in industrial practice [4][5][6][7][8].…”

ABSTRACT. In this study, zirconium oxide (ZrO)-cerium oxide (CeO) based composite coatings were fabricated using doctor blade method to protect pure magnesium from corrosion. The effects of ZrO and CeO on corrosion resistance of magnesium coatings were investigated using Tafel polarization method. Uniform deposition of composite coating without micro-voids was observed from scanning electron microscopy (SEM) analysis. The results exhibit that the addition of CeO show a higher corrosion resistance in comparison with the specimen coated without CeO in the electrolyte and bare Mg, and also it reduces the corrosion rate of Mg up to 3.67 x 10-5 mpy. Surface morphology of the so developed composite coating result a minimum corrosion on the surface. The usage of ZrO/CeO as coating material is a promising anticorrosive measure for Mg and its alloys due to its elevated corrosion resistance and durability.

“…Surface modification can effectively enhance the corrosion performance of Mg alloy and, at the same time, can impart different biological properties to the surface. 12−14 Different surface modification methods such as electrodeposition, 15 microarc oxidation (MAO), 16 ion implantation, 17 anodized oxidation, 18 chemical conversion coating, 19 and polymer coating 20 have been widely used. Among these methods, chemical conversion coating, especially Ca−P conversion coating, is one of the most widely used and effective methods, which can simultaneously enhance the biocompatibility and corrosion resistance of Mg alloys.…”

Magnesium (Mg) and its alloys have exhibited great potential for orthopedic applications; however, their poor corrosion resistance and potential cytotoxicity have hindered their further clinical applications. In this study, we prepared a calcium phosphate (Ca−P) coating with a micro−nanofibrous porous structure on the Mg alloy surface by a chemical conversion method. The morphology, composition, and corrosion performance of the coatings were investigated by scanning electron microscope (SEM), energy-dispersive spectrometer (EDS), X-ray diffraction (XRD), immersion tests, and electrochemical measurements. The effects of the preparation temperature of the Ca−P coatings were analyzed, and the results confirmed that the coating obtained at 60 °C had the densest structure and the best corrosion resistance. In addition, a systematic investigation into cell viability, ALP activity, and cell morphology confirmed that the Ca−P coating had excellent biocompatibility, which could effectively promote the proliferation, differentiation, and adhesion of osteoblasts. Hence, the Ca−P coating demonstrates great potential in the field of biodegradable Mg-based orthopedic implant materials.
