Epitaxial multiferroic BaTiO₃-BiFeO₃ composite thin films exhibit a correlation between the magnetoelectric (ME) voltage coefficient αME and the oxygen partial pressure during growth. The ME coefficient αME reaches high values up to 43 V/(cm·Oe) at 300 K and at 0.25 mbar oxygen growth pressure. The temperature dependence of αME of the composite films is opposite that of recently-reported BaTiO₃...

History and theory of plasma polymerization is reviewed below. The deposition process of metal/plasma polymer composite films and their properties are shortly discussed. The experimental part of the paper describes the preparation procedure and the properties of composite TiOx/hydrocarbon plasma polymer films. The composite films have been prepared by a simultaneous sputtering in argon from two...

This study investigates the preparation of PbSe-ZnSe composite thin films by simultaneous hot-wall deposition (HWD) from multiple resources. The XRD result reveals that the solubility limit of Pb in ZnSe is quite narrow, less than 1 mol%, with obvious phase-separation in the composite thin films. A nanoscale elemental mapping of the film containing 5 mol% PbSe indicates that isolated PbSe nanoc...

in this research, the mechanical properties of seven types of nanofilm with differing amounts of silver and silver-clay particles were studied. the elasticity of modulus, tensile strength, toughness, elongation at break, tear strength and color of nanofilms were compared with those of ordinary ldpe film. results showed that the inclusion of nano particles increased the modulus of elasticity, te...

       Food packaging extensively uses plastic films and containers of petroleum-based polymers for their excellent functional properties and competitive price. Plastic packaging has become a central focus of waste reduction efforts, particularly in aesthetic terms of damage to flora and fauna. Presently, consumers require greater quality and longer shelf lives for their foodstuffs, while they ...

This work reports a novel and general synthesis of aligned carbon nanotube/polymer composite films with high optical transparency, robust flexibility, and excellent conductivity. These composite films show many potential applications such as flexible conductors for optoelectronic devices.

Flexible poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate)/polypyrrole/paper (PEDOT:PSS/PPy/paper) thermoelectric (TE) nanocomposite films were prepared by a two-step method: first, PPy/paper nanocomposite films were prepared by an in situ chemical polymerization process, and second, PEDOT:PSS/PPy/paper TE composite films were fabricated by coating the as-prepared PPy/paper nanocomposite ...

An innovative approach was performed to prepare novel pullulan/starch blended edible films by direct incorporation of multiple probiotic bacterial strains. Various starches different in origin were blended into the pullulan solutions with different ratios. The physical and mechanical properties of the films were investigated in the presence and absence of probiotic cells. An increase in the sta...

Polymer matrix composite materials that can emit radiation in the far-infrared region of the spectrum are receiving increasing attention due to their ability to significantly influence biological processes. This study reports on the far-infrared emissivity property of composite films based on far-infrared ceramic powder. X-ray fluorescence spectrometry, Fourier transform infrared spectroscopy, ...
