Preparation Method Of Porous Ceramic Supported Graphene Film
Strong and permeable macro porous α al 2 o 3 membrane supports are made by colloidal filtration of 20 vol dispersions of α al 2 o 3 with an average particle size of 600 nm.
Preparation method of porous ceramic supported graphene film. Properties preparation and potential applications. Applying the mixture to at least one surface of a substrate. A rapidly increasing list of graphene production techniques have been developed to enable graphene s use in commercial applications. Disclosed is a method of preparing a porous graphene film comprising the steps of.
And then 3 g naoh was added to the solution followed by magnetic stirring and reflux for 1 h. The dope solution composition and the spinning conditions are summarized in table s1. Research on the preparation of polycaprolactone porous films with decoration of protein arrays via the emulsion based breath figure method. The go sil 1 al 2 o 3 composite hollow fibers were prepared according to the detailed parameters as listed in table 1 graphene oxide go was synthesized using an improved hummer s method graphite powder 3 g 325 mesh was stirred with a solution of concentrated h 2 so 4 12 ml k 2 s 2 o 8 2 5 g and p 2 o 5 2 5 g at 80 c for 4 5 h.
Shuangshuang chen su gao jiange jing qinghua lu. Mixing graphene oxide and a solvent to form a mixture. The mixture was cooled to room temperature and. And cooling the at least one surface of the substrate to form water droplets on the surface which depress into the mixture on the substrate to form pores on the substrate surface.
Intact compacts with very good surface quality were obtained at an optimum ph of 9 5 and dosage of 0 2 wt ammonium aurintricarboxylate aluminon based on dry alumina. Preparation of porous graphene pg the prepared graphite oxide go was dispersed into deionized water 750 ml to a final concentration of 0 6 mg ml. Firstly porous diatomite ceramics were cut to samples with dimension of 10 10 15 mm and then these samples were dipped into as prepared go suspension and kept respectively at normal pressure 1 atm for 1 h vacuum condition 1 100 par for 1 h and 48 h. Preparation of reduced go modified porous diatomite ceramics.
The porous graphene obtained by this method is a new 2d. Macromolecular chemistry and physics 2018 219 6 1700500. Subsequently the finally attained mixture was treated by centrifugation at 13 000 rpm for 10 min. Preparation of α alumina support hfms the porous α alumina support hfms support hfms were prepared using an extrusion spinning phase inversion method followed by a sintering process.
Porous cu ni foils were made by electroplating ni on cu foils and used as templates for chemical vapor deposition growth of porous graphene foam.
