Hybrid Carbon

The field of material science is continually evolving with first-class discoveries of new nanomaterials. The element carbon is ubiquitous in nature. Due to its valency, it can exist in various forms, also known as allotropes, like diamond, graphite, one-dimensional (1D) carbon nanotube (CNT), carbon fiber (CF) and two-dimensional (2D) graphene. Carbon nano fiber (CNF) is another such material that falls within the category of CF. With much smaller diameters (around hundreds of nanometers) and lengths in microns, CNFs have higher aspect (length to diameter) ratios than CNTs. Because of their unique properties like high electrical and thermal conductivity, CNFs can be applied to many matrices like elastomers, thermoplastics, ceramics and metals. Owing to their outstanding mechanical properties, they can be used as reinforcements that can enhance the tensile and compressive strain limits of the base material. Thus, in this short review, we take a look into the dexterous characteristics of CF and CNF, where they have been hybridized with different materials, and delve deeply into some of the recent applications and advancements of these hybrid fiber systems in the fields of sensing, tissue engineering and modification of renewable devices since favorable mechanical and electrical properties of the CFs and CNFs like high tensile strength and electrical conductivity lead to enhanced device performance.

AbstractThis short review summarizes our recent progress in fiber-shaped lithium-ion batteries and lithium-air batteries based on carbon nanotube hybrid fiber electrodes. The fiber architecture allows batteries to be deformable in all dimensions and bear various deformations such as bending, tying, twisting and even stretching. They are scaled up and further woven into breathable, flexible, stretchable and shape-memory textiles to effectively meet the requirements of modern electronics such as wearable products.

Strength And Toughness

AbstractReinforcement of cements with very fine fibers of carbon and steel in mono- and hybrid-forms has been investigated. While both carbon and steel fibers led to considerable improvements in strength and toughness, on a comparative basis, carbon fibers bring about a better improvement in the toughness or energy absorption, and the steel fibers impart higher tensile strengths to the base cement matrices. In the hybrid-fiber systems, the improvements lie somewhere in between those of the equivalent mono-fiber systems.

Joining Process

The aim is to analyze a junction produced by a Friction Stir Welding (FSW) joining process under multiaxial loading, employing a modified Arcan test that allows an angle variation of the loading in order to evaluate the failure of the FSW weldment as compared to the base material. A short review of the earlier studies and relevant theories about the FSW processes and fracture modes I and II under multiaxial loading are presented and were experimentally evaluated for an AA2024-T3 aluminum alloy sheets (t = 1.6 mm) processed by FSW. The results obtained can serve as a basis to compare the junctions made using FSW and conventional joint methods such as rivets (very common practice in the aeronautical industry).

The Cost

Attention to carbon fiber (CF) conditioned by their unique physicochemical, mechanical and electrical properties, which makes them in demand in various fields of activity. Today there are several kinds of carbon fibers, most of which (about 90%) are made of polyacrylonitrile (PAN). Despite the fact that carbon fibers are produced from several types of different precursors, their widespread commercial use is limited by the high cost of the product. Has, many research and engineering group seek to reduce the cost of production by using cheap carbon raw materials. A likely solution to this problem is the exploitation of coal, petroleum and coal tar as an effective progenitor for CF production. This review discusses neoteric accomplishment in CF synthesis using various carbon pitches. The possibility of obtaining carbon fibers based on resin with the addition of PAN is presented, and the prospects for their use in energy storage systems and various reinforced composite materials are described in detail.

Bone tissue engineering scaffold provides an effective treatment for bone defect repair. Biodegradable bone scaffold made of various synthetic and natural materials can be used as bone substitutes and grafts for defect site, which has great potential to support bone regeneration. Regulation of cell-scaffold material interactions is an important factor for modulating the cellular activity in bone tissue engineering scaffold applications. Thus, the hydrophilic, mechanical, and chemical properties of scaffold materials directly affect the results of bone regeneration and functional recovery. In this study, a poly-L-lysine (PLL) surface-modified poly(lactic-co-glycolic acid) (PLGA)/graphene oxide (GO) (PLL-PLGA/GO) hybrid fiber matrix was fabricated for bone tissue regeneration. Characterization of the resultant hybrid fiber matrices was done using scanning electron microscopy (SEM), contact angle, and a material testing machine. According to the results obtained from the test above, the PLL-PLGA/GO hybrid fiber matrices exhibited high wettability and mechanical strength. The special surface characteristics of PLL-PLGA/GO hybrid fiber matrices were more beneficial for protein adsorption and inhibit the proliferation of pathogens. Moreover, the enhanced regulation of MC3T3-E1 cell proliferation and differentiation was observed, when the resultant hybrid fiber matrices were combined with electrical stimulation (ES). The cellular response of MC3T3-E1 cells including cell adhesion, proliferation, alkaline phosphatase (ALP) activity, calcium deposition, and osteogenesis-related gene expression was significantly enhanced with the synergistic effect of resultant hybrid fiber matrices and ES. These data indicate that the PLL-PLGA/GO hybrid fiber matrices supported the cellular response in terms of cell proliferation and osteogenesis differentiation in the presence of electrical stimulation, which could be a potential treatment for bone defect.

AbstractPoly(butylene fumerate) (PBF) and poly(butylene fumerate)-co-(butylene maleate) (PBFcBM) have been synthesized from the ring opening and condensation reactions of maleic anhydride (MA) and 1,3-butanediol (BD). PBFcBM synthesized in this way contains greater than 85% maleate groups. Both PBF and PBFcBM have a glass transition temperature (Tg) below room temperature and therefore cannot be electrospun using the conventional electrospinning process as a non-porous film results. To facilitate production of nonwoven micro- and nano-fiber mats, a UV-source (λ=356 nm) was used in combination with a photoinitator loaded polymer solution to initiate the crosslinking reaction of the fumerate and maleate functional groups as the fibers were produced. The resulting non-woven fiber mats are potentially suitable scaffolds for tissue engineering and drug delivery application.
