油墨是实现印刷功能的必备产品。功能性油墨是随着社会的发展、商品市场的扩大以及印刷工业的不断发展而发展起来的新型油墨,功能型油墨正逐渐取代传统油墨,它在印刷电子产品、包装防伪等方面发挥着重要的作用。石墨烯由于其丰富的理化性质,不仅可以复合成多种类的功能型油墨,更给功能型油墨的研发和应用带来了光明的前景。
1 石墨烯的结构、功能及制备
1.1 石墨烯的结构及功能
近年来,石墨烯[1]越来越受到科学界的重视,它具有优异的导电性和光学性能。石墨烯是由sp2杂化而成碳原子组成,它内部的碳原子单元排列呈六边形的蜂窝状;石墨烯是二维单原子层晶体[2],其中σ键与3个碳原子相连,而其π电子通过与碳原子的π电子相连而形成π电子离域,因π电子离域中自由移动的电子使石墨烯具有优异的导电性。……
