A wearable, low-cost, highly repeatable piezoresistive sensor was fabricated by the synthesis of modified-graphite and polyurethane (PU) composites and polydimethylsiloxane (PDMS). Graphite sheets functionalized by using a silane coupling agent (KH550) were distributed in PU/N,N-dimethylformamide (DMF) solution, which were then molded to modified-graphite/PU (MG/PU) composite films. Experimenta...

Studies of polymeric ternary composite thin films incorporating inorganic materials are of immense importance for current technological applications. Polyimide (PI) composite thin films incorporating indium tin oxide (ITO) and poly (vinlylidene fluoride) (PVDF) at various weight ratios were processed using an in situ generation approach with the spin coating unit. The resultant product was oxid...

Lead zirconate titanate (PZT) thick films with uniformly dispersed submicrometer pores were successfully fabricated on platinized silicon substrates with various thicknesses ranging from 1 lm to over 100 lm by aerosol deposition. Mixed powders of PZT and polyvinylidene fluoride (PVDF) were deposited for initial fabrication of composite films. After burn-out of the PVDF phase from the composite ...

BACKGROUND In this work the chemical structure of dextran-iron oxide thin films was reported. The films were obtained by MAPLE technique from composite targets containing 10 wt. % dextran with 1 and 5 wt.% iron oxide nanoparticles (IONPs). The IONPs were synthesized by co-precipitation method. A KrF* excimer laser source (λ = 248 nm, τFWHM≅25 ns, ν = 10 Hz) was used for the growth of the hybrid...

OBJECTIVES/HYPOTHESIS The purpose of this study was to determine the usefulness of edible taste strips for measuring human gustatory function. STUDY DESIGN The physical properties of edible taste strips were examined to determine their potential for delivering threshold and suprathreshold amounts of taste stimuli to the oral cavity. Taste strips were then assayed by fluorescence to analyze th...

in view of the importance environmental pollution caused by plastic food packaging, in recent years there is a considerable interest in edible films and coating based on polysaccharides, proteins, lipids or combination of them. edible coatings also serve as carriers of food additives such as anti-browning and antimicrobials agents, colorants, flavor, nutrients and spices, so act as active packa...

Conducting polymer composite films comprised of polyaniline (PANI) and single wall carbon nanotubes (SWNT) was prepared by electrochemical codeposition during the electropolymerization in an aniline solution with suspending SWNT. The fabricated composite films are assessed with respect to their potential application as support materials in Pt electrocatalyst for electrochemical oxidation of met...

Flexible single-walled carbon nanotubes/polyaniline (SWNT/PANi) composite films with enhanced thermoelectric properties were prepared via a simple method. Furthermore, these paper-like composite films show good flexibility, which makes them possible to be widely applied in various flexible energy converter devices.
