제목 | Preparation of Highly Nanoporous Carbon Materials with Honeycombed Structure using a Unidirectional Freeze-dried Polyamic Acid Precursor |
초록 | We performed uniaxial freeze-drying using a synthesized poly(amic acid) (PAA) derivative that is soluble in 1,4-dioxane. By virtue of the high carbonization yield and homogenous shrinking properties of PAA, we successfully manufactured carbon materials with a microcellular structure using the freeze-dried PAA precursor. The structured carbons showed an extremely high porosity of ca. 90.8%, a high specific surface area of 2038 m2/g, and a high micropore volume of 0.60 cm3/g. |
