Hello, I need some help on how to make automotive ceramic coatings that use sio2/tio2/graphene.
I need the product to be give incredible shine. Willing to work with a chemist and pay for advice or whatever you may desire to do in my company we can work something out.
Bonus: if you know how to make automotive products like compounds/polishes/wax/sprays that would be helpful. Thank you
Dear Bozen,
Automotive ceramic coatings that use sio2/tio2/graphene. Is A novel nanohybrid composite of TiO2, SiO2, reduced graphene oxide (TiO2@Si:Fe:rGO) is fabricated by the sol–gel method. The properties of the coated film were examined by structural and self-cleaning analyses using simulated discoloration/soiling and roofing tests. The coated substrate is excellent resistance to simulated acid rain and significantly preserved the substrate from soiling in roofing tests. The surface modality of the ceramics can be observed and characterized under scanning electron microscopy (SEM). The group of silica coating + Titanium+ graphene oxide attains the highest shear bonding strength used specially to dentin.
Refer these methods:
Prabhu[4] given below, prepared the reduced graphene oxide (rGO)/TiO2 composite self-cleaning material according to the solvothermal method and improved the visible light absorption efficiency of the composite self-cleaning materials, which exhibited the good photocatalytic efficiency and super-hydrophilic performance under light irradiation.
Synthetic process:
Sol-gel processed silica layer was applied on the PC substrates prior to TiO2 coating. A silica sol was prepared by adding 1.5 mL TEOS in 4 mL ethanol and this mixture hydrolysed by adding 3 mL of double distilled water with 1 mL of nitric acid. Stir overnight and spin-coated on UV-treated PC substrates at 2000 rpm. This silica coating can annealed at 100 °C for 2 h A crack-free surface morphology and low surface roughness compared to the coatings prepared from the higher vol% of SiO2 in TiO2. The water drops on this coating acquires a contact angle less than 10° after UV irradiation for 30 min. For further, graphne addition refer [4] no which may be quite useful for you.
