Graphene Based VOC Absorbing Sponge

Brief description: Graphene Based VOC Absorbing Sponge is a VOC absorbing material with super-high absorbing rate and speed, and excellent cycle performance. 

Features:

-Super hydrophobic, water contact angle>150o, no water absorption from air

-high adsorption rate, absorbing toluene gas: over 70 times of its own weight (For comparison, 7 times for carbon fiber, 0.5 times for activated carbon)

-Fast adsorption, reaching 64.8 times of itself weight within 30 minutes in adsorbing toluene gas

-Easy desorption, by means of heating, negative pressure, etc., desorption rate of over 98%

-High cycle efficiency, over 95% absorption rate/96% desorption rate after 100 times desorption
