High dielectric constant polyaniline/epoxy composites via in situ polymerization for embedded capacitor applications

Synthesis, characterization, and comparative study of conducting polyaniline/lead titanate and polyaniline–dodecylbenzenesulfonic acid/lead titanate composites

“…This is due to (110), the plane of the perovskite structure, and the peak at 2y 5 56.48 with a d-spacing of 1.637 Å corresponds to (222), the plane of the pyrochlore structure of PbTiO 3 . 34 These results confirm that the nature of polycrystalline oxide is also observed in these composites similarly to the cases of PANI-V 2 O 5 35 and PANI-MoO 3 . 36 The increased crystallinity in the case of composites is basically due to the incorporation of PbTiO 3 into the polymer matrix, and this is supported by the previous results.…”

Improvement of insulation effectiveness of natural rubber by adding hydroxyl-functionalized barium titanate nanoparticles

“…Surface functionalization of the nanoparticles is a convenient approach to improve dispersion of the nanoparticles within the nanocomposite structure since it allows reinforcing the interfacial interaction between the polymeric matrix and the nanoparticles [17]. Surface modification of the nanoparticle fillers produces a surface coating layer that increases the electric field strength at breakdown and lowers the dielectric loss [22]. Yu et al [23] reported that the addition of surface modified BaTiO 3 particles in poly(vinylidene fluoride) enhances the dielectric properties and reduces dielectric loss, even at high filler loading.…”

Enhancement of Electrical and Mechanical Properties of SU-8 Photocrosslinked Coatings Containing Polypyrrole-graphene Oxide Nanoparticles

“…The observed higher tan δ value of the SU-8/PPy-GOs than that of pure SU-8, Fig. 4(C), is associated with the free charge motion difference, indicating an interfacial polarization occurring in the SU-8/PPy-GOs [26].…”
