“…The rheological behavior of the precursor will dictate the feasibility of the spinning process. The rheology behavior of the blend solution will change drastically from polymer blends, nanofiber/polymer, and nanoparticle/polymer . Rheology property of the blend solution is sensitive to the physical properties of the materials and also depends on the surface tension and miscibility of the two materials.…”

Continuous carbon nanofibers had been widely studied based on different processing methods and precursors. Especially, electrospinning was introduced as a versatile method for fabricating ultrathin fibers. However, as the limitation of precursor, pitch had not been well studied due to its viscosity and miscibility problem. A comprehensive study on the electrospinning of the blends [pitch and polyacrylonitrile (PAN)] was explored. Thermodynamic miscibility was studied by using differential scanning calorimeter. Fourier transfer infrared spectroscopy was used to show interaction and potential reaction between pitch and PAN molecules. Finally, smooth, continuous, and cylindrical carbon nanofibers were successfully fabricated by electrospinning technique. Based on Raman analysis result, the addition of pitch enhanced the carbon crystallite which improved the overall electrical conductivity and modulus of nanofibers.

“…al found the addition of ND on poly(lactic acid) (PLA) to increase dynamic mechanical properties on injection molded samples 26 . The influence of ND on PCL electrospinning fibers 27 and poly(LLA-co-CL) films 28 was also investigated by other authors. However, no published paper studying the incorporation of ND on P(3HB) or any of the PHA polymers was found.…”

Studies regarding biodegradable nanocomposites to be used as orthopedics devices have been intensified. This work aims to investigate the influence of ND dispersion on thermal and mechanical properties of a biocomposite of poly(3-hydroxybutyrate) (P(3HB)) reinforced with nanodiamonds (ND) intended to be used as orthopedics devices, with advantages as biodegradability. In order to improve its dispersion, P(3HB) has encapsulated ND in three different mass ratios: P(3HB):ND(16:1), (12:1) and (8:1). However, for all formulations, NDs are presented as agglomerates, in different intensities. In order to relate the distribution of ND within the polymer matrix and biocomposite properties, TGA, DSC, and DMA analysis were done. The formulation with higher content of ND, P(3HB):ND(8:1), presents larger aggregates; thus, decreasing its properties. With smaller and more distributed agglomerates, the 12:1 ratio composite displayed superior storage modulus and glass transition temperature, probably due to better polymer chain restriction.

“…Uniform ND-PVA nanofibers were obtained, and the related cell attachment results suggested their potential usefulness in biological applications (Salaam et al, 2014). ODA passivated, ND was electrospun with PCL for enhancing mechanical strength and adding photoluminescence to the end products (Cao et al, 2015). Ahn et al (2018) …”

“…Takimoto, Chano (Takimoto et al, 2010) introduced fluorescence to ND through a multistep covalent linking approach, and then the FND was introduced to HeLa cells which were imaged fluorescent successfully. FND was introduced with PCL to act as an optical probe for tissue engineering and sub-dermal imaging applications (Cao et al, 2015;Fox et al, 2016). Nanocomposites of ND-ODA with PLLA was formed with the purpose to monitor bone regrowth when replacing the implant in vivo (Zhang et al, 2011).…”

The biocompatibility of materials is the determining factor for them to be applied in biomedical areas. Nanodiamond (ND) has gained increasing interest in this area due to its biocompatibility, ease of surface functionalization and excellent mechanical performance. ND has been widely used to reinforce biopolymers, and the resultant biocomposites have found applications in bone tissue engineering, chemotherapeutic drug delivery, and wound healing. Fluorescent ND, when combined with biopolymers, is serving for bioimaging and sensing applications. Herein, we contribute a description of ND, recent trends in its adoption for biopolymers, functionalization methods, amalgamation techniques of ND with biopolymers, potential applications of these composites in the biomedical field and future perspectives.biocompatibility, biocomposites, biopolymers, nanodiamond, scaffold
