“…Combining metal nanoparticles and polymers enhances the optical properties and alters the mechanical behavior of the polymer composite [1]. Employing a high refractive index material in optical applications frequently requires higher optical transparencies [1][2][3][4]. Polymers with high refractive index have fascinated several research groups due to their potential applications in cutting-edge optoelectronic devices such as organic light emitting diode devices [5], high performance substrates for advanced display devices [6], antireflective coatings for advanced optical applications [7] and micro lens components for charge coupled devices or complementary metal oxide semiconductor [8].…”

We report the synthesis and characterization of Poly Methyl-Meth-Acrylate (PMMA)/Poly vinylalcohol (PVA) polymeric blend doped with different concentrations of Copper oxide (CuO) nanoparticles (NPs). The (PMMA-PVA)/CuO nanocomposite hybrid thin films (wt. % = 0%, 2%, 4%, 8%, and 16%) of CuO NPs are deposited on glass substrates via dip-coating technique. The transmittance (T%), reflectance (R%), the absorption coefficient (α), the optical constants [refractive index (n), extinction coefficient (k)], optical dielectric functions [ɛ',ɛ''] are investigated and interpreted. Tauc, Urbach, Spitzer-Fan, and Drude models are employed to calculate the optical bandgap energy (Eg) and the optoelectronic parameters of the nanocomposite thin films. The refractive index and optical bandgap energy of of (PMMA-PVA) polymeric thin film are found to be (1.5 to 1.85) and 4.101 eV, respectively. Incorporation of specific concentrations of CuO-NPs in (PMMA-PVA) polymeric thin films leads to a noticeable decrease in the optical bandgap energy and to an increase of the refractive index. Moreover, Fourier Transform Infrared Spectroscopy (FTIR) transmittance spectra are measured and analyzed for undoped and doped polymeric thin films to pinpoint the major vibrational modes in the spectral range (500 and 4000 cm-1), as well as, the nature of network bonding in both systems. Thermal stability of thin films is investigated by performing thermogravimetric analysis (TGA). The TGA thermograms confirm that both doped polymeric thin films are thermally stable at temperatures below 110°C which enables them to be attractive for a wide range of optical and optoelectronic applications. Our results indicate that optical, vibrational and thermal properties of both polymeric thin films can be tuned for specific applications by the appropriate corporation of particular concentrations of CuO-NPs.

Highly flexible and visibly transparent yellow–green fluorescent poly(vinyl alcohol) (PVA) based nanocomposite (NC) films with rubidium zincate (Rb2ZnO2) nano impregnates were developed through aqueous solution casting. The introduced rubidium zincate nanofillers impart UV shielding properties to PVA host, through UV to visible (fluorescent yellow–green) photon cutting. The rubidium zincate nanofiller impregnated PVA systems were also characterized for their structural, morphological, optical, and electrical behaviors by various analytical tools. The Fourier Transform Infrared (FTIR) and X‐ray diffraction (XRD) studies shed light on the changes in gross structural properties of PVA. WhileScanning Electron Microscopic (SEM) profiles support uniform filler dispersions, which aid high visible transparencies. Further, the UV–visible spectral measurements depict the changes in electronic band structure that validates novel fluorescent emission properties, established through fluorescent emission studies. The NC films show excellent visible transparency (72–84%), near hydrophobic surface wettabilities (ϴ = 82°–93°) and enhanced charge conduction, in addition to high flexibilities and UV photons induced fluorescent emission ( λEmi=585 nm). The yellow–green luminescent, Rb2ZnO2 nanofillers reinforced PVA NC films are effective spectral manipulators, which may be used as competent packaging materials for photonic display devices and to extend the short wavelength limit of solar cells. © 2018 Wiley Periodicals, Inc.

Poly(vinyl alcohol) (PVA) has been considered as an important commercial synthetic thermoplastic polymer. PVA is a low cost, reasonably processable, optically transmitting, heat stable, and mechanically robust plastic. PVA-based nanomaterials usually comprise of the nanocomposites (PVA/graphene, PVA/carbon nanotube, PVA/nanodiamond, PVA/metal nanoparticle) and nanofibers. The structural, optical, mechanical, and electrical properties of the PVA-based nanomaterials have been enhanced with nanofiller addition or nanostructuring. This review offers fundamentals and advanced aspects of poly(vinyl alcohol) and the derived nanomaterials. It highlights recent advances in PVA nanocomposites and nanofibers for potential applications. The PVA-based nanomaterials have been successfully employed in fuel cells, sensors, batteries, membranes, electronics, and drug delivery relevances. The challenges and opportunities to strengthen the research fields of PVA-based nanomaterials have also been presented.
