“…Uniform dispersion of nanosized metal oxide in the polymer matrix introduces more conducting paths and that leads to higher conductivity. These results are in good agreement with recently reported work . It can be concluded that the fabricated PVCin/NiO nanocomposite exhibits remarkable electrical and magnetic properties, which may find application in various electromagnetic shielding, high‐frequency electric devices.…”

A poly(vinyl cinnamate) (PVCin) composite was synthesized by a simple one step in situ polymerization of vinyl cinnamate with nickel oxide (NiO) nanoparticles. The structural, morphological and thermal properties of the nanocomposite were characterized using Fourier transform (FT)‐Raman, FT infrared (FTIR) and UV spectroscopies, X‐ray diffraction (XRD), high‐resolution transmission electron microscopy (HRTEM), field emission scanning electron microscopy (FESEM), differential scanning calorimetry and vibrating sample magnetometry (VSM) measurements. FT‐Raman, FTIR and UV spectroscopy results revealed the characteristic absorption and shifts of peaks of the polymer matrix, the shifts being attributed to the interaction of NiO nanoparticles with the polymer chains. The structural and morphological analysis using XRD, HRTEM and FESEM showed the uniform arrangement of nanoparticles within the polymer chains. VSM showed the ferromagnetic nature of the composite with an increasing saturation of magnetism. The glass transition temperature (Tg) of the composite was higher than that of pure PVCin and Tg of the composite increased with increasing nanoparticle content. The electrical resistivity of the nanocomposite was studied from AC and DC conductivity measurements. AC and dielectric properties were markedly enhanced in the whole range of frequency due to the presence of NiO nanoparticles. DC conductivity of the nanocomposite was much higher than that of PVCin and the conductivity of the nanocomposite increased with increasing content of NiO nanoparticles. © 2016 Society of Chemical Industry

“…Both pristine HNTs and modified HNTs showed strong peaks at 3697 and 3615 cm −1 , respectively, which correspond to the stretching vibration of Al-OH groups in the inner surface; at 1028 and 909 cm −1 , peaks corresponded to Si-O stretching and Al-OH bending vibrations, respectively [57]. Meanwhile, minor peaks at 2932, 2359, 1680, and 1540 cm −1 , corresponding to C-H stretching vibration, carbonyl group [58], hydrogen bonding of COOH groups [59], N-H bending vibration [60], and C-N stretching vibration [61], respectively, could be seen in the gelatin-modified HNTs spectrum rather than in the spectrum of pristine HNTs.…”

The study involved research related to the selection of the material with improved functional properties that can be used for dental prostheses. An innovative system of nanofillers, that differ in shape, by means of gelatin-modified halloysite nanotubes (HNTs-g) along with silane-coupled aluminum trihydrate (ATH-sil) was prepared, in order to observe a synergistic improvement of acrylic material (methyl methacrylate with methyl methacrylate monomer (MM/mMM)). Selected mechanical properties of manufactured nanocomposites, along with utilitarian properties, like hardness, buffer solution absorption, and abrasion resistance, along with a fall test from the height of finished products have been discussed. Moreover, the study of the biofilm formation on the surface of dental prostheses confirmed the occurrence of a synergistic improvement of properties and the legitimacy of using modified mineral nanofillers in the form of a hybrid system.

“…Researchers also have used conductive fillers like carbon black, graphene nanoplatelets along with CNT so that they support the conductive network of each other, and thus, offer better conductivity . Few articles are also reported based on CNT and PANI hybrid filler system wherein CNT is proposed to form conductive bridges between sparse PANI particles, thereby, lowering the percolation threshold .…”

Carbon nanotubes and polyaniline filled hybrid epoxy composites: Assessing the viscoelastic behavior and mechanical properties

et al. 2018

In the current work, polyaniline (PANI) and epoxy (EP) composites were prepared and the effect of carbon nanotubes (CNT) addition to EP/PANI (5%) composite on mechanical and viscoelastic properties was studied. PANI was synthesized using p‐toluenesulfonic acid (PTSA) as dopant and characterized through UV–vis and FTIR spectroscopy. Viscosity of uncured EP and composites was studied as a function of shear rate and found to increase with fillers concentration. Dynamic mechanical analysis revealed that PANI increased the storage modulus wherein glass transition temperature (Tg) almost remains constant. Addition of 0.1% CNT to EP/PANI (5%) composite further raised the modulus whereas 0.4% CNT had no significant effect on storage modulus due to agglomeration. However, peak intensity of tan δ curve and Tg were improved for both CNT concentrations. Mechanical properties like tensile, flexural, and impact strength remained unaltered at low PANI (5%) content while at high loading these properties deteriorated significantly. 0.1% CNT has marginal effect on mechanical strength of EP/PANI (5%) system while 0.4% CNT notably reduced the properties. Morphological studies showed that PANI had good dispersion in matrix at lower loading (5%) while it forms uniformly distributed aggregates at higher contents. PANI dispersion was not affected by inclusion of CNT. POLYM. COMPOS., 40:E1143–E1150, 2019. © 2018 Society of Plastics Engineers
