Shape: Cylinder

Size:  d:~1cm;h:~2.5cm

Specific surface area:~ 360 m2·g-1

Density: ~30 mg·cm-3

 

Product Features

 

Three dimensional porous structure: Nitrogen doped graphene sponge has a stable three-dimensional network structure, providing a huge specific surface area and rich pore structure, which is conducive to the adsorption of gases and liquids and the occurrence of catalytic reactions.

High conductivity: Nitrogen doping can improve the conductivity of graphene, making nitrogen doped graphene sponge potentially applicable in electronic devices, sensors, and other fields.

Excellent mechanical properties: Nitrogen doped graphene sponge exhibits good flexibility and elasticity, capable of withstanding certain compression and bending without fracture.


Application Fields

 

Energy storage: Nitrogen doped graphene sponge can be used in energy storage devices such as supercapacitors and lithium-ion batteries to improve energy density and cycling stability.

Environmental purification: By utilizing its high specific surface area and excellent adsorption performance, nitrogen doped graphene sponge can be used to adsorb and degrade harmful gases (such as formaldehyde, benzene compounds, etc.) in the air, achieving air purification.

Sensor: The high conductivity and fast response to resistance of nitrogen doped graphene sponge make it suitable for preparing electronic devices such as piezoresistive sensors for detecting physical quantities such as pressure and deformation.

Biomedical: In the field of biomedicine, nitrogen doped graphene sponge can be used in drug delivery systems, biosensors, and other applications, utilizing its excellent biocompatibility and special properties to achieve controlled drug release and accurate detection of biological signals.

Buy them!
Ok I was a little hesitant based off these reviews but I decided to try them anyways. OMG I am a chronic face picker and cause sooo much scarring. And I always do it right before summer which causes horrible dark spots that take years to fade. Well I had one that was in a particularly noticeable spot and omg after only 3 days…3 it looks so much better with these patches!!! Don’t get me wrong it isn’t gone but for 3 days that is unreal. I will be using until it’s gone for sure!

Subtle but works!!
Okay there are PRICEY for the small amount you receive. I believe they work for sure and will buy them again but which they would put a FEW MORE in a pack because they are not like miracle patched and you definitely need two packs to see a significant difference.

Did nothing for hyperpigmentation, worked well on active blemish
I use these for an active blemish and they work well for reducing inflammation and redness. They are marketed for hyperpigmentation, but they didn’t seem to have much of an effect on lingering redness from an old breakout after a few uses so I decided to use them on a whitehead that popped up on my chin. I bought two packages and had passed the return window so I figured couldn’t hurt. After a few hours with this patch on, the whitehead and surrounding redness virtually disappeared. They are almost invisible on the skin IF you can remove them from their clamshell packaging without scrunching up and wrinkling the edge of patch. BIG IF!!! Most of the time I mess up the edge of the patch making the wrinkled edge visible on my face. I wear them around the house so I don’t really care about that, but it’s worth mentioning. You have to remove them from the packaging VERY carefully to keep the patch smooth. I’ve been mostly unsuccessful at removing them without scrunching up an edge. Oh well. Peach Slices makes a similar product for acne, “deep blemish microdarts”. I haven’t tried those, nor do I plan to because the amount of product that you get for either kind of micro dart is not a good value to me. I wish these were less expensive. I do like the way the micro dart feels when you apply it- kind of a satisfying stinging sensation- like the ingredients are really penetrating. I would not call it painful. A moment of sting and it’s on there doing it’s job. It stays on well while doing basic daily activities (like doing the dishes, working at a desk). Can’t say how it would hold up to something more vigorous like a jog or bike ride or anything that would make you break a sweat. I like the product and the result on blemishes, but I can’t justify the cost. A warm compress and followed by a vitamin C serum on a blemish works just as well and it’s way more cost effective, albeit less convenient. Also, the ingredients in the product description are incomplete. See photo- they contain Butylene Glycol which is sometimes irritating to my skin. Luckily, these patches didn’t irritate me. Having to 3rd party check the ingredients for cosmetics from Amazon irritates me though 😒 If these are affordable for you for the occasional blemish, I would recommend. Did nothing for hyperpigmentation and way too expensive for me to combat a full breakout or even a daily random pimple. I’ll use the ones I have but would not purchase again.

Didn’t Work for Me
This purchase was a complete waste of time and money for me. The dots did absolutely nothing to reduce the color of a sun spot on my cheek. I used them according to the instructions for consecutive days. The dots are gone, but the spot on my skin remains as dark as before. Maybe they work better for pimple discoloration.
