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.

XF210 WS2 dispersion was prepared by liquid-phase exfoliation method, resulting in a 2H phase. According to different application requirements, various solvents such as water ethanol, DMF, NMP, etc. can be selected as dispersion media.

Product Features

Single crystal and high purity: The liquid-phase exfoliation method can prepare single crystal tungsten disulfide nanosheets with a pure 2H phase structure.

Good dispersibility: The dispersion of tungsten disulfide nanosheets obtained by liquid-phase exfoliation method has good dispersibility and can stably exist in various solvents, such as water ethanol, DMF, NMP, etc.

Multifunctionality: Tungsten disulfide nanosheets have enhanced electronic, optoelectronic, sensing, and catalytic properties, making them suitable for fields such as electrochemical energy storage, electrochemical catalysis, device manufacturing, and biological research.

Low friction coefficient and high compressive strength: As a lubricant, tungsten disulfide has better performance than molybdenum disulfide, with lower friction coefficient and higher compressive strength.


Application Fields

Semiconductor materials: Tungsten disulfide nanosheets are widely used in the semiconductor field due to their unique electronic properties.

Electrochemical energy storage: In batteries and fuel cells, tungsten disulfide nanosheets can be used as electrode materials to improve energy density and cycling stability.

Catalyst: Due to its high specific surface area and active sites, tungsten disulfide nanosheets exhibit excellent catalytic performance in catalytic reactions.

Biological detection and medical applications: In the biomedical field, tungsten disulfide nanosheets can be used for biological imaging, drug delivery, and biosensors.

Great squeaker balls - dogs favorite but not for aggressive chewers.
We have a chocolate Labrador retriever and a golden retriever who love balls. Tennis balls don’t last. We’ve been very happy with the ChuckIt quality. We especially love the bucket of orange balls those last until we lose them. We’ve tried to other products from ChuckIt and they’ve always been excellent. Squeaker toys are a special favorite in our home. However most don’t last because our dogs are moderately aggressive chewers. They haven’t destroyed these… yet. HOWEVER, we have a ball-obsessed, very aggressive chewer grand dog Sadie (“Ball Is Life”) who visits frequently. She goes nuts over anything that squeaks. She’s not satisfied until all squeakers are dead. And she destroy this ball in about 2 minutes. It’s fine when she supervised and we’re playing fetch. But when left on her own, she’ll find these balls and destroy them. We had 6 and in 2 days were down to four. I will still give it 5 stars because nothing is indestructible. And Sadie is an exceptionally aggressive chewer. On durability, these are above average maybe 7/10. But be warned, aggressive chewers will destroy them.

Durable except squeaker only works for a few minutes
My pups loves these balls mostly for the squeaker. Company dose not glue the squeaker in place inside of the ball so after a few chews from pup the squeaker pops out n bounces around the inside of the ball. Than after awhile the end pops out n that's a good thing for me due to I'm able to glue the squeaker back in place then glue end back also. Now the squeaker works again. Easy fix yet company should have done this before my pups played with them. Scary, what if my pups chew the ball n by chance chocks on the squeaker? I now take the ball apart when they 1st arrive n glue the squeaker n end in place the day before they play with them. Company should just glue the squeaker in place before they sell them to keep our pups safe from chance of chocking.

My dog’s all-time favorite toy!!
My boxer mix LOVES LOVES LOVES the Chuck it ball! It is seriously his favorite toy. I think he likes how much give it has when he chomps on it, kind of like a dog stress ball. It does squeak when chewed but the squeak typically goes away in about a week likely due to saliva getting inside the ball. It bounces really well, my dog loves to catch it mid-bounce. Nice smooth rubber, easy to clean. It is very durable, we’ve never had one that broke. We usually only have to buy more when they go missing. The size is similar to a tennis ball. I’ve also noticed there is a difference between the mostly blue chuck it ball and the mostly orange one. The orange one is harder than the blue. My dog can tell the difference and only likes these blue ones.
