基本信息
| General description【一般描述】 | We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Green Chemistry. This product has been enhanced for energy efficiency. Click here for more information. |
| Application【应用】 | This product is a thixotropic ink based on graphene oxide (GO) nanosheets. It is suitable for various direct ink write (aka robocasting) printing technologies. The ink offers a stable dispersion of GO, high viscosity, good printability, and long shelf life. Freeze-dried and annealed patterns provide low electrical resistivity and high surface area. The ink is suitable for applications such as batteries, supercapacitors, electrocatalysis, etc. |
| Preparation Note【制备说明】 | Before Printing: Bring the ink to room temeprature, best to mix the ink in a planetary mixer before usage. Printing: Recommended 3D printing nozzle diameter size is 400 micron. Post printing: After 3D printing, this ink can be directly freeze-dried in liquid nitrogen and vacuum to obtain free- standing graphene oxide aerogel. This ink can also be processed by adding gelling agents to enable a covalent bond established between the graphene oxide sheets. Gelation agents such as ammonium carbonate, ammonium hydroxide, resorcinol formaldehyde have all been reported to be sufficient. After gelation, the wet GO gels printed parts are washed in acetone to remove water from the pores. Supercritical CO2 can then be used to dry the GO gels. Curing: Parts that are printed with gelling agent can be cured in sealed glass vials at 85 ℃. The dried aerogels are generally reduced to graphene aerogels by thermal treatment at 1050 ℃ under inert atmosphere. Other chemical reduction methods include hydrazine reduction, dried aerogels can also be reduced using hydroiodic acid, followed by washing in ethanol, water and then freeze drying. |
