Abstract Ferroelectric thin films are playing a growing role as key elements in variety of devices. For various techniques ferroelectric film preparation, the sol-gel processing is one most promising. In comparison with different deposition techniques, we survey intrinsic advantages and recent improvements processing. this review paper, several interesting topics, including epitaxial growth grain-orientation, symmetric asymmetric P-E hysteresis loops, heterojunction effect interface between...
Land and energy play key roles in coal-based cities where the extensive exploitation use of coal resources have resulted resource abuse serious pollution. Here, we used substance flow analysis integrated nexus theory to establish a new model for life-cycle embedded with land–energy nexus. The includes mining, processing, product utilization, waste disposal. Then firstly apply analyze land consumption Huainan City which is typical city China from 1990–2020. results show that unit decreases...
Transparent ferroelectric strontium barium niobate (SBN) thin films were made on fused silica, silicon, and GaAs substrates by the sol-gel process. The microstructure of these was studied. Preferentially oriented SBN silica can be obtained applying a dc electric field during heat treatment. A heterojunction effect further confirmed demonstration photocurrent. optical, pyroelectric, ferroelectric, electro-optic properties measured. An optical refractive index 2.31 effective linear...
This paper explores the use of sodium alginate, polyvinyl alcohol and polyethylene glycol. Chemical cross-linking creates a high-toughness support structure, forming corrosion-resistant, electromagnetic shielding hydrogel.
Abstract Carbon nanotubes (CNTs) are widely utilized as conductive fillers due to their high conductivity, lightweight, and ease of modification. However, poor dispersion limits otherwise excellent performance. In this study, we successfully prepared a toughness, strong electromagnetic interference (EMI) shielding hydrogel by blending polyvinyl alcohol (PVA) with multi‐walled carbon (MWCNTs) modified anionic surfactant sodium dodecylbenzene sulfonate (SDBS) (3‐aminopropyl) triethoxysilane...
Abstract Electromagnetic interference (EMI) shielding materials with easy processing, high electrical conductivity, and excellent absorption loss are urgently needed in aerospace, military stealth portable electronic devices. In this study, a polyvinylidene fluoride/multi‐walled carbon nanotubes (PVDF/MWCNTs)‐3 wt% composite film prepared by simple solution mixing polyethylene terephthalate (PET) nonwoven scraping method was used as the substrate, PVDF/MWCNTs/graphene oxide@multi‐walled...
Several ferroelectric thin films with n-type or p-type conductivity, including undoped and doped lead zirconate titanate, barium strontium niobate, potassium as well were made on silicon single-crystal substrates by the sol-gel process. Self-biased heterojunction effects observed in both p-ferroelectric film n-silicon n-ferroelectric p-silicon measurement of current-voltage characteristics. It has been that either p-n junction n-p ferroelectric-semiconductor systems behave like a rectifying...
From 15 K to room temperature, dielectric and pyroelectric properties have been measured in six ferroelectric niobate single crystals with tungsten-bronze (TB) structure. Dielectric experiments show that the three kinds of ${\mathrm{Sr}}_{1\mathrm{\ensuremath{-}}\mathrm{x}}$${\mathrm{Ba}}_{\mathrm{x}}$${\mathrm{Nb}}_{2}$${\mathrm{O}}_{6}$, ${\mathrm{Pb}}_{\mathrm{x}}$${\mathrm{Ba}}_{1\mathrm{\ensuremath{-}}\mathrm{x}}$${\mathrm{Nb}}_{2}$${\mathrm{O}}_{6}$,...
