Product Overview

Tungsten disulfide (WS2) is a type of transition metal sulfide (TMDC) with a graphene like layered structure, where the layers are stacked together by weak van der Waals forces. Single layer WS2 is composed of three layers of atoms, with the atomic planes of W and S arranged in a hexagonal array. The W atoms are sandwiched between the two layers of S atoms, forming an S-W-S atomic layer structure with a "sandwich" structure. Multi layer or block WS2 is composed of single layers stacked together. Depending on the stacking method of the single layers, WS2 has three crystal structures: 1T, 2H, and 3R.

The synthesis methods of WS2 are mainly divided into two categories: "top-down" stripping method and "bottom-up" method. The "top-down" exfoliation method includes micro mechanical exfoliation, liquid-phase exfoliation, and lithium-ion intercalation, mainly using physical means to exfoliate the bulk WS2 into a single-layer or few layer layered structure. The "bottom-up" method includes chemical vapor deposition, hydrothermal method, and high-temperature thermal decomposition method, mainly using chemical means to grow atoms and molecules into nanoscale thin films and granular WS2 under certain environmental conditions.

Product Features

Layered structure: composed of a layered structure similar to graphite, with weak bonding between layers.

Good lubrication performance: With a low coefficient of friction, it performs well in the lubrication field and can effectively reduce wear between mechanical components.

Excellent electrical performance: It is a semiconductor material with certain conductivity and potential applications in electronic devices.

Good stability: It is not prone to chemical reactions with other substances in the environment and can maintain its structure and properties at high temperatures.

Application Fields

Lubricant: WS ¡ãCis a solid lubricant widely used in equipment for high temperature, high pressure, high speed, high load, and transportation in chemically active media.

Petroleum catalyst: WS ¡ãCcan be effectively used as a catalyst for hydrogenation, desulfurization, polymerization, reforming, hydration, dehydration, and hydroxylation processes due to its excellent cracking performance, high catalytic activity, and long service life.

Energy storage electrode material: WS ¡ãCis a layered material with good thermochemical stability, lithium storage performance, and fast electron transfer rate, which can effectively improve the energy density and structural stability of electrode materials.

Additives for high-performance lubricants: Adding an appropriate amount of WS ¡ãCnanoparticles to the lubricant can greatly improve its lubrication performance, reduce friction coefficient, and increase oil film strength.

Exactly what I needed!
Color: Natural, Size: 6 Panels
My main use for this may be different than most people. I was taking care of some kittens and wanted to keep them away from sensitive areas of the living room (wires, home theater equipment, etc.). At first I stacked some boxes around, which was rather ugly and ineffective (made it harder for ME to get around more than anything else). I went online looking for a better solution and found this room divider. This did the trick! Finally I could have a stress-free time while the kittens were running around, and with something that actually improved the look of the room too. The divider itself is put together very well. The hinges actually fold both ways, so you get some versatile configuration options. It is lightweight and easy to move around, making it very easy to stash out of the way when not in use. I was so pleased that I went and bought 2 of the smaller 4-panel dividers as well, to use in a different area.

UNhappy Customer!
Color: Natural, Size: 6 Panels
Quite honestly I dont normally give poor reviews. I dont normally get poorly made products from Amazon but this time has changed things for me. I will order very little and will especially be mindful of anything made in China! This divider arrived in an intact but wet box. It took me nearly 20 minutes to get it to unfold. The two outside panels flipped out freely but for some reason I had to work to get the other panels to unfold. When it did open, the second panel was clearly damaged. I proceeded to prepare it for return, taped it up securely, requested and received a return label and traveled to the UPS store to return. Wouldn't you know it...UPS shipping charges were $154.00!!! More than I paid for this inferior product. So, if I return on my dollar and hope it makes it to the appointed destination and receive $151.99 for the return cost, I'm out $154.00 and no product to show for it! Its amazing how sellers come up with ways to unload their junk and then prevent satisfied customers by making them pay for the return shipping costs. I opted to keep the junk and consider it a lesson learned. What a scam!
