| 摘 要： | 采用静电自组装技术,通过交替沉积聚(二烯丙基二甲基氯化铵)(PDDA)(或硝酸银)和氧化石墨烯,制备氧化石墨烯/PDDA薄膜和氧化石墨烯/硝酸银复合薄膜。然后在600℃下通入氩气和氢气进行气氛还原得到石墨烯薄膜和石墨烯/银复合薄膜。采用AFM、SEM、XPS、UV-Vis以及四探针电阻仪等对薄膜结构及性质进行表征。结果表明,通过静电自组装法可以获得生长均匀的薄膜。对比于相同自组装次数的石墨烯薄膜,石墨烯/银复合薄膜具有更好的透光性和更低的薄膜方块电阻。在λ=500 nm时,四层石墨烯/银复合薄膜的透过率为85%左右,而石墨烯薄膜的透过率为72%左右;石墨烯薄膜的方阻为161.39 kΩ.□-1,而石墨烯/银复合薄膜的方阻为99.11 kΩ.□-1。

| Abstract: | By alternating deposition of poly(diallyldimethylammonium chloride)(PDDA) or silver nitrate,and graphene oxide(GO) sheets via electrostatic self-assembly process,two self-assembled multiplayer films(GO/PDDA film and GO/AgNO3 composite film) are successfully prepared.In order to make the films electrically active,a reduction treatment involving the thermal annealing in Ar/H2 atmosphere at 600 ℃ are conducted.The films are studied by means of AFM,SEM,XPS,UV-Vis and four-probe resistance measurement instrument.The results show that these two kinds of films are surface uniform.And the graphene/Ag film has better optical properties and electrical properties.The transmittance of four layers graphene/Ag film is 85%,better than that of graphene film(72%);the sheet resistance of graphene/Ag film is 99.11 kΩ·□-1,which is lower than that of graphene film(161.39 kΩ·□-1). |
