摘要
Abstract
The expandable graphite prepared by chemical oxidizing process was mixed with CuO and Fe3O4, respectively,and then expanded at 900 ℃.The expanded volumes of the doped exfoliated graphite (EGs) were tested,and the IR screening characteristics of the doped EGs were tested by a static screening testing system.Results show that the expanded volume of CuO doped EG decreases from 245 mL · g-1 to 130 mL · g-1 ,and the correspongding shielding efficiency decreases from 78.4％ to 48.3％.The expanded volume of Fe3O4 doped EG decreases to 190 mL · g-1 ,and its shielding efficiency decreases to 73.7％.The IR shielding efficiencies of the two doped EGs are both inferior to that of the EG.关键词
