Functional polymer films (FPFs) have drawn increasing interests recently for their promising applications. Unfortunately, it still remains a challenge to fabricate large-area FPFs by a facile, continuous and environmentally friendly method. Herein, via coextrusion blow film molding, sandwiched...

The presence of silicon oxyphosphide in the heavily phosphorus-doped n + -type polycrystalline silicon film (poly Si) of TOPCon solar cell has been mainly revealed through a depth-profile X-ray photoelectron spectroscopy (XPS) characterization of chemical components. X-ray diffraction (XRD)...

Pt nanoparticle-dispersed tungsten trioxide (Pt-WO3) gasochromic switchable films are fabricated from a precursor solution containing oxalic acid at room temperature without any heat treatment. The color of the fabricated Pt-WO3 films changed between transparent and deep blue states after being...

The rapid development of terahertz technology is accompanied by serious electromagnetic pollution, it is extremely imminent to prepare high efficiency terahertz absorbers. However, currently terahertz absorbers mostly concentrate on complex structural absorption-based metamaterials and thicker...

This work focused on the development of active film used for food packaging based on Poly (lactic acid) (PLA) reinforced with olive wood flour (OWF). The biofilm was produced by solvent casting with different wood flour contents, where the OW0, OW1, OW3, OW5, and OW10 biofilms were chosen (0, 1,...

Grain size is a critical factor determining materials properties but is challenging to be modulated in nanoscale. Here, we found the grain size can be enhanced from ~23 nm to ~557 nm for Cu but slightly from ~30 nm to ~145 nm for Cu 96 W 4 with the substrate temperature from 298 to 773 K using...

The electric field manipulation of a magnetic order is a key feature of advanced information technologies and the development of room-temperature multiferroic magnetoelectrics remains an important task. In this work, we report novel single-phase magnetoelectric (ME) films consisting of a (Co...

The polyvinylidene fluoride (PVDF)-Ba 0.8 Sr 0.2 TiO 3 (BST) nanocomposite facile thick films of thickness ~100 μm have been synthesized by tape-casting technique. Only 5 wt % of Ba 0.8 Sr 0.2 TiO 3 (BST) nanoparticles are incorporated in the PVDF matrix. An electric field of 22 kV/mm (for...

The pure and silver nitrate-doped polyvinyl alcohol films were synthesized using Dip Coating method. The effect of different concentration of silver nitrate (AgNO 3 ) on the electrical and optical properties of Polyvinyl alcohol (PVA) films were investigated. The synthesized composite films were...

Transition metal dichalcogenides (TMDs) with unique layered structure and interesting electronic properties, which has the narrower band-gap and high electron-hole recombination rate, limiting its application in many optical devices. The combination of wide and narrow is an excellent strategy...
