合成了一种含功能化石墨烯的双噻唑聚合物(SDS-GNS)及其配合物SDS-GNS-Cu2+,利用红外光谱、X射线衍射分析等对其结构进行了表征;通过综合热分析得出SDS-GNS和SDS-GNS-Cu2+的失重速率分别为4.8%/℃和5.7%/℃,说明聚合物SDS-GNS和配合物SDS-GNS-Cu2+具有较好的热稳定性;通过常温测定聚合物SDS-GNS和配合物SDS-GNSCu2+的电化学特性,采用交流阻抗拟合方法,获得SDS-GNS和SDS-GNS-Cu2+的电导率分别为2.03×10-6S/cm和2.32×10-6S/cm。

Synthesis of a functionalized graphene containing bis-thiazole polymer (SDS-GNS) and its complex SDS-GNS-Cu2 +, the use of infrared spectroscopy, X-ray diffraction analysis of its structure were characterized by comprehensive thermal analysis was The weight loss rates of SDS-GNS and SDS-GNS-Cu2 + were 4.8% / ℃ and 5.7% / ℃, respectively, indicating that polymer SDS-GNS and complex SDS-GNS-Cu2 + had good thermal stability. The electrochemical properties of SDS-GNS and SDS-GNSCu2 + were investigated by AC impedance fitting method. The conductivity of SDS-GNS and SDS-GNS-Cu2 + were 2.03 × 10-6 S / cm and 2.32 × 10- 6S / cm.
