“…In the literature, there are several cases of porphyrins subjected to electrospun deposition in combination with electrospinnable polymers, so that their dispersion [26] and arrangement inside fibers as well as their photocatalytic [27] and sensing features [28,29] have been investigated extensively [30]. On the other hand, the best performances seem to be achieved when porphyrin occupies the outer part of the fiber [31] or when polymer fibers are very porous. Electrospun polymer fibers with a ternary composite combination (porphyrin, graphene oxide and nylon) are also manufactured [32] to be investigated towards more advanced applications.…”

Structural and functional properties of polymer composites based on carbon nanomaterials are so attractive that they have become a big challenge in chemical sensors investigation. In the present study, a thin nanofibrous layer, comprising two insulating polymers (polystyrene (PS) and polyhydroxibutyrate (PHB)), a known percentage of nanofillers of mesoporous graphitized carbon (MGC) and a free-base tetraphenylporphyrin, was deposited onto an Interdigitated Electrode (IDE) by electrospinning technology. The potentials of the working temperature to drive both the sensitivity and the selectivity of the chemical sensor were studied and described. The effects of the porphyrin combination with the composite graphene–polymer system appeared evident when nanofibrous layers, with and without porphyrin, were compared for their morphology and electrical and sensing parameters. Porphyrin fibers appeared smoother and thinner and were more resistive at lower temperature, but became much more conductive when temperature increased to 60–70 °C. Both adsorption and diffusion of chemicals seemed ruled by porphyrin according its combination inside the composite fiber, since the response rates dramatically increased (toluene and acetic acid). Finally, the opposite effect of the working temperature on the sensitivity of the porphyrin-doped fibers (i.e., increasing) and the porphyrin-free fibers (i.e., decreasing) seemed further confirmation of the key role of such a macromolecule in the VOC (volatile organic compound) adsorption.

In this paper, the PVA/HNTs composite nanofibers with well-enhanced mechanical properties were successfully prepared by electrospinning technique. The structure and properties of the composite nanofibers were characterized by TEM, XRD, FT-IR, and DSC. The results indicated that the highly oriented and dispersed HNTs wrapped in polymer matrix were achieved by inducing function during electrospinning processing. The mechanical properties of the PVA/HNTs composite nanofibers depended on HNTs content were investigated, which showed 72.4% increase in tensile strength at optimal filling content.

“…Such a polymer-nanoparticle composite has stipulated the flexibility, stability and the conformational ability for complicated structures while maintaining the nanoparticle traits. [1][2][3][4][5][6] The demanding qualities of compactness and portability of the electronic devices expedite the advancement of flexible electronics in various perspectives. This mechanism of fabricating flexible electronics has been regarded a low temperature process and involves facile processing methods and usage of Ultra Violet (UV) curable materials.…”

In this paper, UV shielding properties of the fibrous composite membranes of PVA and ZnO have been studied and analyzed. Two kinds of approches have been adopted to prepare the fibrous membrane and their corresponding effect on shielding properties have also been systematically studied. It has been observed that the pure PVA fibrous membrane with a wavelength longer than 230 nm could not be filtered which predicted that transparency of the pure PVA samples for both UVA and UVB radiations. In the case of DDM derived composite membrane, UV radiations in the range from 200 to 365 nm have been efficiently absorbed by the sample. The ISM-PVA/ZnO exhibit impressive UV shielding nature which effectively filtered the whole range of UV radiation especially for both UV-B (280-315 nm) and UV-A (315-400 nm). The transmittance results indicate a significant improvement of the UV absorbing property of ISM derived ZnO/PVA. Considering the simplicity of the fabrication of the composite materials, this work might become very useful for commercial exploitation.
