The pristine graphene produced by liquid exfoliation of graphite in mixed solvent and its application to determination of dopamine.

本文报道了在异丙醇（IPA）-水混合溶剂中借助焦磷酸钠（Na4P2O7·10H2O）辅助，通过液相剥离法制备原始石墨烯（PG）的方法。超声剥离并离心收集上清液后，PG分散液浓度可达0.565 mg/mL，较无盐IPA/水体系显著提高，接近或高于部分高沸点混合溶剂体系。滴涂所得PG膜电导率达7.095×10^4 S/m。将PG修饰于玻...
