“…To the best of our knowledge, the CNR/PVA composite nanofiber film fabricated by green electrospinning technique has not been reported so far. However, natural rubber and its modified derivatives have been incorporated into commercial polymers such as poly(caprolactone), acrylonitrile butadiene styrene, and poly(lactic acid) and then electrospun in solution to prepare nanofiber materials . The advantage of those works was to find new application for natural rubber in nanofiber research area with an increase in tensile modulus and elasticity.…”

Green electrospinning technique was employed to prepare chloroacetated natural rubber (CNR)/poly(vinyl alcohol) (PVA) nanofiber films by varying the addition of PVA in the range 2.5–55 wt % followed by encapsulation of 2.5 wt % fumed silica (FS). In this study, the risk of using organic solvents was eliminated using CNR in latex. The encapsulated electrospun fiber mats showed a fairly homogenous composition with enhanced water absorption ability of 703.54% ± 33.95%. The FS improved the interfacial adhesion and contributed to enhancing the intermolecular interaction between the two polymers. The mean diameter of the nanofibers decreased from 64.0 ± 19.0 to 41.0 ± 13.0 nm and significant improvement in the hydrolytic and enzymatic degradation rate was observed implying that FS can facilitate the degradation rate. Furthermore, loading of PVA and encapsulation of FS resulted in an improved stiffness of CNR at room temperature and storage modulus increased to 2.48 and 2.12 MPa, respectively. © 2018 Wiley Periodicals, Inc.

“…This work reports the production of a new biomaterial based on electrospun PLA/NR blends which combine the properties of a very well-established polymer as PLA with those of NR, which has been cited as an interesting biomaterial due to its recently discovered biological properties [22] [23]. In this approach, important properties of PLA as solubility in common solvents, biodegradability, good mechanical properties, and biocompatibility [24] [25] are combined with those of natural rubber (NR) as recently demonstrated applications in stimulating wound healing, angiogenesis, and tissue regeneration [22] [23].…”

The electrospinning method is chosen due to its capability of providing membranes with a very large surface area which can offer ideal space for cell adhesion and proliferation, also the porous structures can provide windows for oxygen and nutrients transfer when the scaffolds are used in tissue engineering applications.…”

This article reports the production of electrospun fibers from blends of poly(lactic acid) (PLA) and epoxidized natural rubber (ENR) solutions. The produced fibers were characterized by scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR), differential scanning calorimetry (DSC), thermogravimetric analysis (TGA) and dynamic mechanical analysis (DMA). SEM images showed the reduction in fiber size with ENR content of up to 25% in the mixture PLA/ENR. FTIR analysis revealed a possible interaction between carboxylic group of PLA and epoxi group of ENR. Thermal analysis showed the increase of the crystallinity fraction with ENR content and a decrease in thermal stability of eletrospun mats with the addition of ENR. The dynamic mechanical properties showed an enhancement of the stiffness of PLA/ENR blends with the increase of ENR content, which can support the production of interesting materials for tissue engineering based on renewable and biocompatible polymers. The reported properties indicate the possibility to use such fiber mats as potential materials in tissue engineering.

“…Only few attempts of electrospinning elastomers/rubbers are currently reported in literature, due to their poor spinning ability in conventional solvent systems, which is related to their viscoelastic behavior at room temperature and fiber formation mechanism during electrospinning. For example, only fibers based on polybutadiene rubber (BR) [7][8], synthethic cis-1,4-polyisoprene [9], blends of natural rubber (NR)/acrylonitrile butadiene styrene (ABS) [10] and of NR/polycaprolactone (PCL) [11] were successfully obtained by electrospinning technique. To the best of our knowledge, actually none of the papers reported in literature deals with sole natural rubber.…”

The interest towards natural rubber (NR) is progressively increasing due to its sustainable production and remarkable mechanical properties, presenting a wide application range in the automotive industry and civil engineering. In this paper we report, for the first time, the use of electrospinning technique to produce neat and graphene nanoplatelets (GNPs, 1 wt.%) loaded natural rubber fibers. Both randomly distributed and aligned fibers (average diameter size ~ 1 μm) mats were obtained, resulting uniform and defect-free. A detailed characterization of these fibers is reported, including field emission-scanning electron microscopy (FEG-SEM), X-Ray diffraction (XRD) and infrared spectroscopy (FTIR-ATR) techniques. It has been demonstrated that the electrospinning process is able to induce a strong orientation of the polymeric chains in the case of aligned fibers, with respect to the randomly oriented fibers and solvent cast films
