“…This attributed to higher aspect ratio, better dispersion and interfacial stress transfer of rGO compared to xGnP. Good dispersion and interfacial stress transferring lead to a more uniform stress distribution and minimize the presence of the stress concentration center [29]. The effect of rGO and xGnP on tensile modulus and elongation at break are shown in Figures 6 and 7, respectively.…”

Abstract:The superlative mechanical properties of graphene-based materials make them the ideal filler materials for polymer composites reinforcement. Two types of graphene-based materials, graphene nanoplatelets (xGnP) and reduced graphene oxide (rGO), were used as nanofiller in poly(lactic acid) (PLA) polymer matrix, as well as plasticized PLA. The addition of rGO into PLA or plasticized PLA substantially enhanced the tensile strength without deteriorating elasticity, compared to xGnP nanocomposites. In addition, the investigation of the thermal properties has found that the presence of rGO in the system is very beneficial for improving thermal stability of the PLA or plasticized PLA. Scanning electron microscope (SEM) images of the rGO nanocomposites display homogenous and good uniformity morphology. Transmission electron microscopy (TEM) images revealed that the rGO remained intact as graphene sheet layers and were dispersed OPEN ACCESS Polymers 2014, 6 2233 well into the polymer matrix, and it was confirmed by X-ray diffraction (XRD) results, which shows no graphitic peak in the XRD pattern.

“…A large number of patents and articles about lactic acid polymers have been published in recent years (Jompang et al 2013;Padee et al 2013;Pivsa-Art et al 2013;Li et al 2014;Shi et al 2015). Although demand for PLA has expanded, its current production capacity of 450 million kg per year is dwarfed by the 200 billion kg of total plastics produced per year.…”

Lactic acid is a naturally occurring organic acid that can be used in a wide variety of industries, such as the cosmetic, pharmaceutical, chemical, food, and, most recently, the medical industries. It can be made by the fermentation of sugars obtained from renewable resources, which means that it is an eco-friendly product that has attracted a lot of attention in recent years. In 2010, the U.S. Department of Energy issued a report that listed lactic acid as a potential building block for the future. Bearing the importance of lactic acid in mind, this review summarizes information about lactic acid properties and applications, as well as its production and purification processes.

“…Due to its simpler protocol and equivalent conductivity upon reduction, the improved Hummers method is attractive for preparing GO on a large scale. Recently, Li [26] reported that GO prepared by the improved Hummers method could obtain a high grafting rate of poly (L-lactic acid) (30.8%) at a moderate condition. …”

Graphene oxide (GO) can be readily modified for particular applications due to the existence of abundant oxygen-containing functional groups. Graphene oxide-based materials (GOBMs), which are biocompatible and hydrophilic, have wide potential applications in biomedical engineering and biotechnology. In this review, the preparation and characterization of GO and its derivatives are discussed at first. Subsequently, the biocompatibility and tribological behavior of GOBMs are reviewed. Finally, the applications of GOBMs as lubricants in bio-tribological systems are discussed in detail.
