Reactive compatibilization effect of graphene oxide reinforced butyl rubber nanocomposites

The increasing concerns about solid waste disposal have led to the development of innovative strategies for repurposing waste materials. This paper describes a simple solution casting process for recycling postconsumed footwear leather fiber (PCF) into a biocomposite film reinforced with graphene oxide (GO) and polyvinylpyrrolidone (PVP). PVP was utilized as a compatibilizer to strengthen the interfacial bonding of GO and leather fiber via π–π interactions. UV–visible spectroscopy, Fourier transform infrared spectroscopy, X-ray diffraction, thermogravimetric analysis, and scanning electron microscopy were used to examine the material dispersibility bonding between GO and PCF, structural properties, thermal properties, and surface morphology of the biocomposite films, respectively. Compared to pure PCF film, the oxygen transmission rate of the prepared biocomposite films is elevated by 64% as well as the biodegradability rate is intensified up to 60%. In addition, the film’s tensile strengths are raised by 216%, while their elongation at break is increased by 164.64% as compared with PCF. The versatility of these eco-friendly and biodegradable composite films extends to its possible applications in packaging and interior design. The outcomes of the research reveal the viability of manufacturing affordable and sustainable biocomposites through the utilization of waste leather from consumed footwear.

<div class="section abstract"><div class="htmlview paragraph">Rubber is one of the most used materials currently selected to produce automotive parts, but, for specific applications, some improvement is required in its properties through the addition of some components to the rubber compound formulation. Because of that, mechanical, thermal, and chemical properties are enhanced in order to meet strict requirements of the vast range of application of the rubber compounds. In addition to improving material properties, the combination of different substances, also aims to improve processability and reduce the costs of the final product. Recently, the use of nanofillers has been very explored because of their distinctive properties and characteristics. Among the nanofillers under study, graphene is known for its high-barrier property, thermal and electrical conductivities, and good mechanical properties. A large number of researches on rubber/graphene compounds preparation methods and applications can be found in literature and results are promising, including for rubbers largely used in automotive industry, such as acrylonitrile butadiene rubber (NBR), natural rubber (NR) styrene butadiene (SBR), butyl rubber (IIR), and ethylene-propylene-diene (EPDM). The observed improvements obtained with the addition of graphene in rubbers can have a good impact on durability and performance of a lot of different rubber automotive parts, such seals, hoses, tires, and anti-vibration parts. This work is an overview about rubber-graphene compounds, bringing aspects of preparation methods and some final characteristics that can be valuable for automotive industry, such as mechanical and chemical resistance, and barrier property.</div></div>
