An ultrahigh capacity supercapacitor is fabricated using a nano-layered MXene as an active electrode material, and Ni-foil used current collector. The high-quality Ti3C2Tx obtained from supernatant during etching washing processes improves the specific capacitance significantly. As another strategy, surface of engineered by coating chemical vapor deposition-grown graphene. graphene grown directly on collector, forming structure Ti3C2Tx/graphene/Ni. passivation collectors has high impact...
Among various available materials used in transparent and flexible devices, MXenes are attracting attention as a brand-new candidate this category. Ti3C2Tx MXene 2D material has exceptional properties, making it potential having numerous applications different areas. Because of its high conductivity, can be conducting electrodes (TCEs). In study, the etched by highly concentrated acid at 50 °C,were spin-coated on polyethylene terephthalate (PET) film annealed moderate temperatures up to 170...
A vacuum-coupling technique is suggested to fabricate a glass-based PDLC, without using roll-to-roll process, improve the optical properties.
We have studied liquid crystals (LCs) and acrylate-assisted thiol-ene compositions to synthesize dye based colorful polymer dispersed (PDLCs) without using a photo-initiator for smart-windows applications. A typical PDLC mixture was prepared by mixing LCs with UV-curable monomers, which included triethylene glycol diacrylate (TEGDA), trimethylolpropane diallyl ether (TMPDE, di-functional ene monomer), tris(3-mercaptopropionate) (TMPTMP, thiol as cross-linker), dichroic dye. The ratios of the...
The effect of Ti3C2T x MXene etched at different temperatures (25 °C, 50 and 80 °C) on the capacitance supercapacitors without use conducting carbon-black or a binder was studied. using concentrated HCl acid (12 M)/LiF used as an active electrode Ni-foil current collector. It observed that elevated etching temperature facilitates MAX phase exfoliation layers. However, this led to formation additional functional groups surface increased °C. specific -based from 581 F g-1 for 25 °C 657 those...
