Abstract
一種石墨烯材料的數量表面積的定量方法，其包括以下步驟。將石墨烯材料與溶液混合以形成含有石墨烯材料的膠體溶液。霧化膠體溶液，以形成多個含有石墨烯材料的氣溶膠。對氣溶膠的尺寸進行篩選。對篩選後的氣溶膠進行計數，以得到篩選後的氣溶膠的數量值。使篩選後的氣溶膠的表面帶電，並量測表面帶電的氣溶膠的電流量。依據電流量及數量值計算石墨烯材料的數量表面積。
A quantitative method of number surface area of a graphene material includes the following steps. The graphene material is mixed with a solution to form a colloidal solution containing the graphene material. The colloidal solution is atomized to form a plurality of graphene-containing aerosols. The size of the aerosols is screened. The screened aerosols are counted to obtain a quantity value of the screened aerosols. A surface of the screened aerosols is charged and an amount of current on the surface charged aerosols is measured. Based on the amount of current and the quantity value of the screened aerosols to calculate the number surface area of the graphene material.
