水可分散性石墨烯-聚苯胺复合物合成初探

摘要

以氧化石墨烯（GO）为模板，利用其巨大的比表面积，将苯胺单体吸附在GO的表面，制备了氧化石墨烯一聚苯胺（G—PANI）复合材料，由于GO表面聚苯胺颗粒比溶液中的聚苯胺颗粒尺寸小，引起紫外可见光谱吸收峰的蓝移。实验证明，由于GO与水具有较强的亲和力，造成G—PANI在水中具有较好的分散性。%The graphene oxided can be used as a template to absorb aniline onto its surface by virtue of its huge spe- cific surface area to prepare complex material of graphene and polyaniline （ G - PANI）. The size of PANI from GO surface was less than that from solutions, resulted in the blue shift of UV spectra. It was demonstrated that the affinity between GO and water led to well dispersing of G - PANI in water.
