Product Overview


The process of preparing graphene by CVD mainly includes three important influencing factors: substrate, precursor, and growth conditions. Among them, the substrate is an important condition for the growth of graphene. Currently, 8-10 transition metals (such as Fe, Ru,Co,Rh,Ir,Ni,Pd,Pt,Cu,Au), And alloys (such as Co Ni, Au Ni, Ni Mo, stainless steel). The mechanism of preparing graphene by CVD varies among different substrate materials, mainly divided into two preparation mechanisms: carburization and carbon deposition mechanism, which involves the infiltration of cracked carbon into the substrate at high temperatures and the formation of graphene on the surface during rapid cooling; The surface catalytic mechanism refers to the formation of graphene on the surface of carbon after cracking at high temperatures when it comes into contact with a specific metal (such as copper), and protects the sample from further deposition of thin films. Therefore, this mechanism is more likely to form single-layer graphene.

In practical applications, the synthesis method of CVD graphene film may vary depending on specific experimental requirements and conditions. Researchers typically optimize and adjust the synthesis process based on target performance and application scenarios. Meanwhile, new synthesis methods and technologies are constantly developing and exploring to improve the quality and performance of graphene films.

Usually, graphene is first grown on a metal substrate, then spin coated with PMMA and transferred onto substrates such as silicon oxide, quartz, glass, PET, or copper mesh.

Great face gems!
Color: Pink
I’ve been really happy with these pink face gems and self-adhesive hair jewels. The designs are super cute and sparkly, with hearts and stars that add a fun, festive touch to Valentine’s Day makeup, festivals, raves, or any playful look. They’re easy to use since they are self-adhesive, so there’s no extra glue needed and they go on smoothly without fuss. The gems stick well and stay in place through movement, dancing, or photos, and they feel comfortable on the skin and in the hair without itching or irritation. The pink shades are bright and eye-catching, making them perfect for girls and women who want a bit of bling. For the quality, sparkle, and fun factor, these rhinestone stickers offer excellent value for the money. If you’re looking for a quick way to elevate your makeup or costume with glittery accents, these jewels are a great choice.

Very comfortable. Good stickiness.
Color: Gold, Color: Gold
These face/body gems are decent quality. It comes with a generous amount of gems - 3 sheets of gems in various sizes. A couple of the gems arrived with defects - the gold paint had flaked off some parts to show black underneath. Most of the gems were in good condition though. These are very lightweight and comfortable to wear. I forgot I had them on at one point and was reminded when I looked in the mirror. The adhesive did not irritate my skin at all and I wore them for a few hours. I was also able to reposition the gems several times without them loosing their staying power. I had to be careful when removing the gems from the plastic sheet because sometimes the adhesive dot would stay stuck to the plastic sheet and the gem would come off without any adhesive attached. I was able to put it back down and get it to re-stick to the adhesive and then carefully remove them together in order to apply it on my skin. Overall I'd say these are worth the purchase.

Bling that is shiny and some of the prettiest pinks - perfect for Valentine's Day!
Color: Pink, Color: Pink
For just about 5 dollars you get 3 sheets of Pink Face Gems/Hair Jewels by VVPESCA. These gems come in the prettiest pinks and have an amazing shine to them. You get your traditional gems of different sizes, but also some that come in unique hearts and stars shapes. I tried sticking them on my face and they stuck very well! I was shocked that they did not come sliding off, even with make-up on. However, when I was ready to remove them, they did come off surprisingly easy and did not leave any sort of mark or irritation. I have not tried them in my hair just yet, but based off of the high quality, I think it would work equally as well. This set of bling comes with a tweezer tool to help remove the gems from their sheets and apply them precisely where you want them. It is more helpful than I realized, as I originally tried placing them on with my fingers and it just didn't cut it as well as the tweezers. I love this set of bling! These jewels are truly great for anytime, but they are especially cute for Valentine's day. I will be wearing some that day to add a little something special!

Cute, with effective self adhesive
Color: Gold, Color: Gold
These are super cute. I’ll start with the packaging: The kit comes all together in a plastic pouch. There are three sheets of gold stud stickers, and a separately packaged pair of application tweezers. The sheets are individually packaged with a thin cardboard backing to keep them from wrinkling, and they themselves are stuck onto a transparent sheet of plastic. They are secured with tiny plastic double sided stickers on the back, similar to double sided tape. Note: sometimes the stud pulls right off the sticker, but you can grab that bad boy gently with the tweezers, peel it off, and stick it right back on without losing any adhesive property. I decided to just experiment with them to see how they work. I was able to move the studs from one part of my face to another, testing out what different piercings might look like, and on the third location change I just left them there and they stayed perfectly fine without falling off. So don’t let the occasional sticker pulling away from the stud concern you; the self adhesive is actually pretty legit! I know I look like I haven’t slept in three years, but including a picture after I had already moved them around a few times so you can see how they managed to keep their stickiness. I plan to do an elaborate makeup look and utilize them for it tomorrow so I might come back and add cooler pictures of that as well!
